AppImage: give appimagetool the version

appimagetool writes the desktop entry's X-AppImage-Version itself, from
the VERSION environment variable, and replaced the one the build had
added with "UNKNOWN" (#49). The build now exports VERSION instead.

+- **The Hunter's Dream** (thehuntersdream.com): sign in with Discord from the launcher (a code is
+  confirmed on the site); no BBSC.
+
+On Windows the module is `online\bbnet20.dll` (Seamless Hunt with BBSC; the launcher's *Online*
+section). The Linux folder package keeps it open as `online/libbbnet20.so`, and `BB_NET_MODULE`

+public server (`srv.shadps4.net`) accepts only shadPS4's own builds. Offline the module is never

+
+## Windows
+
+Since 0.7 bbport runs natively on Windows 10/11 (x86-64, a Vulkan 1.3 GPU with a current driver:
+AMD Adrenalin, NVIDIA GeForce, Intel Arc). The same code as on Linux: the game's x86-64 code runs
+directly, the runtime's POSIX layer is implemented on Win32 (`gpu/platform/win32`), and the
+game's memory is shared with Vulkan through `VK_EXT_external_memory_host`.
+
+**Package:** `Bloodborne-bbport-<version>-windows-x64.zip`. Unpack it anywhere (not into *Program Files*), start
+`Bloodborne.exe`, choose the game folder (the one with `eboot.bin`), press *Play*. Insert (or
+holding L3+R3) opens the port's menu in the game. Everything the port writes stays in that folder:
+`bbport.ini` (settings), `user\` (saves, shader cache), `out\` (prepared game files), `logs\` (one
+log per run: for a report send the newest one). `Bloodborne.exe --play` starts the game without
+the launcher window (through `bbport-run.exe`).
+
+**Launcher:** WPF in the Windows 11 style, following the system's light or dark theme, in five
+languages; the same settings as on Linux (sections with descriptions), monitor, controller and
+GPU choice, the log of the running game, *Stop*.
+
+**Upscalers:** FSR 3.1 and FSR 4 as on Linux. FSR 4.1.1: choose *Build from an AMD DLL…* and pick
+`amd_fidelityfx_upscaler_dx12.dll` 4.1.x; the recording runs on vkd3d-proton and DXVK from the
+package (`tools\fsr4cap\bin`), so any GPU with Vulkan can build the set (a minute or two, into
+`fsr4_411\`). FSR 4.1.2's models (INT8 for RDNA2/3, *Lite*): pick the driver's `amdxcffx64.dll`
+(Adrenalin 26.10.1 or newer, `C:\Windows\System32\DriverStore\FileRepository\u0*\`) together with
+the upscaler DLL. DLSS and DLSS Frame Generation (GeForce RTX): with `bin\bbport_dlss.dll` and
+NVIDIA's `nvngx_dlss.dll` / `nvngx_dlssg.dll` in the package.
+
+**NVIDIA:** at start the port adds a *prefer maximum performance* power profile for
+`bb-probe.exe` to the driver, unless you chose a mode in NVIDIA's Control Panel yourself
+(`BB_NV_POWER=0`: leave it alone); presentation uses FIFO (`BB_NVIDIA_MAILBOX=1`: Mailbox).
+
+**Online play:** the launcher's *Online* section, the same two pools as on Linux (Seamless Hunt
+with BBSC, The Hunter's Dream with Discord sign-in), UPnP and a connection check; the module is
+`online\bbnet20.dll`. **Mods:** the launcher's *Mods and patches* section, as on Linux.
+
+**Building:** in MSYS2's CLANG64 shell (`mingw-w64-clang-x86_64` toolchain, CMake, Ninja, Python,
+SDL3, glslang), or cross-built from Linux with llvm-mingw; the package
+is made by `packaging/windows/package.sh` (the launcher needs the .NET 9 SDK). DLSS:
+`DLSS_SDK_ROOT=<NVIDIA's DLSS SDK for Windows>` (`sdk/DLSS-windows`).

 ## Roadmap
 
-- The new memory and translation model on by default once it is stable and tested on NVIDIA;
-  the old model is removed after that.
+- NVIDIA on Windows: more reports from RTX cards in the heaviest views.
 - Textures as objects created at load time (less guessing by address, uploads outside the
   frame).
-- Shaders translated ahead of time, at install, not during play.
+- All of the game's shaders translated ahead of time (today: recipes from players' caches).
 - More CPU parallelism in GPU command processing (split the draw-recording stage further),
   scaling to all hardware threads — most important for the Steam Deck.
 - Async compute for the upscaler (the frame is GPU-bound at 4K).
 - XeSS (super resolution) and XeFG frame generation through a Wine helper sharing Vulkan
   memory (a memory-bridge prototype is in `tools/bridge_helper`); inputs exposed so that OptiScaler-style mapping works.
-- Frame generation (FSR 3.1 FG first), reactive and transparency masks for particles and fog.
+- Reactive and transparency masks for particles and fog.
 - Fix the races in AMD's FSR 4.1.1 shaders at output widths that are not multiples of 64
   (e.g. 1600×900), as already done for the left-edge race in FSR 4 v07 at 1080p.
 - Steam Deck validation of the AppImage; HDR output.

-модели памяти (см. ниже).
-
-> **Файлов игры в репозитории нет.** Нужен свой дамп Bloodborne с обновлением 1.09: любое издание
-> из магазина (CUSA00900 в США, CUSA03173 — европейское Game of the Year, ...): у них один и тот же
-> исполняемый файл.
-> Проект не связан с Sony Interactive Entertainment, FromSoftware и AMD.
-
-**Состояние: экспериментальный, играбельный.** Игра запускается, загружает сохранения и
-проходится (Сон Охотника и несколько локаций Ярнама) со звуком,
-геймпадом и сохранением. Полное прохождение не проверено; основательно проверена одна машина
-(Linux, AMD Radeon RX 7800 XT, Mesa/RADV).
-
-## Что сделано
-
-- **Нативное исполнение.** eboot заранее превращается в плоский образ памяти, в который как
-  нативный код прилинкованы libc и libSceFios2 из PS4. Никакой эмуляции процессора и
-  трансляции инструкций: код игры работает на полной скорости.
-- **Две модели памяти** (лаунчер → *Режим работы → Модель памяти и трансляции*; *Авто*, по
-  умолчанию, выбирает по видеокарте):
-  - **Старая модель памяти, как в 0.3, — по умолчанию на NVIDIA, Intel и других.** Копии памяти
-    игры в VRAM, записи отслеживаются защитой страниц. Со всеми исправлениями после 0.3
-    (векторы движения и апскейлер, мерцание при включённом DoF, повреждённый кэш шейдеров).
-  - **Новая модель памяти и трансляции — по умолчанию на AMD.** Память
-    игры находится в оперативной памяти, и GPU читает её на месте, как буферы игры для ПК; то,
-    что он читает часто, держится в видеопамяти и освобождается, когда перестаёт использоваться
-    (текстуры — через 20 с, буферы — через 60 с). Модуль памяти прослойки отслеживает записи CPU
-    в блоки с зеркалами для согласования данных; вся память, видимая GPU, не копируется.
-    Работа командного процессора PS4 переводится в команды Vulkan, а не
-    эмулируется на процессоре: записи в память (`WRITE_DATA`, DMA) выполняет видеочип в порядке
-    потока команд, метки (fences) пишет сам видеочип в конце конвейера, в той же точке потока,
-    что и командный процессор PS4.
-    На AMD память игры держится в sparse-буфере (арене); на NVIDIA, Intel и других — через модуль
-    памяти прослойки: привязывается на месте, копии в VRAM — отдельные буферы, без
-    sparse-перепривязок (на NVIDIA sparse binding держал видеочип секундами); `BB_LAYER_MEMORY=1/0`
-    — выбрать вручную. Проверено на RX 7800 XT. На NVIDIA её можно выбрать
-    вручную (*Новая*); у тестеров результат зависит от сцены, в части сцен медленнее старой
-    модели, поэтому там она пока не по умолчанию. На Intel не проверялась. Без лаунчера —
-    `BB_PC_MODEL=1/0` (не задано — по видеокарте, как *Авто*).
-
-  [Изменения в 0.5](docs/CHANGES_0.5.md); пререлизы: [pre4](docs/CHANGES_0.5-pre4.md),
-  [pre3](docs/CHANGES_0.5-pre3.md), [pre2](docs/CHANGES_0.5-pre2.md).
-
-  Неиспользуемые текстуры освобождаются в обоих режимах, поэтому видеопамять больше не растёт
-  с каждой локацией.
-- **Разблокированная частота кадров.** Патчи сообщества (`patches/Bloodborne.xml`) переводят
-  симуляцию на реальное время кадра; ~90 FPS в 4K с FSR 4 Balanced на RX 7800 XT, ~150 FPS в
-  1440p с FSR 4 Quality. Есть режимы 30/60/90 FPS.
-- **Временной апскейлинг под эту игру.** Буфера скоростей в Bloodborne нет, поэтому порт
-  считает векторы движения сам: движение камеры — по глубине и матрицам сцены, движение
-  объектов (персонажи, ткань, оружие) — по позициям вершин прошлого кадра. Сцена сдвигается
-  субпиксельным jitter (Halton) и рисуется в уменьшенном разрешении, апскейлер достраивает
-  вывод (720p для Steam Deck, 1080p, 1440p или 2160p), интерфейс рисуется сразу в выходном разрешении.
-  - **FSR 3.1** (FireBurn/FSR-Vulkan).
-  - **FSR 4 (INT8, модель v07)** на видеокартах с нужными возможностями шейдеров Vulkan,
-    включая RDNA2/3 (см. требования).
-  - **FSR 4.1.1**: DLL AMD 4.1.1 один раз записывается под vkd3d-proton, а её проходы
-    воспроизводятся нативно в Vulkan; результат **побитово совпадает** с DLL. Два варианта, как
-    в самой DLL: INT8 на любой видеокарте с нужными возможностями шейдеров и матрицы FP8 на
-    RDNA4 (RX 9000; выбирается сам). Ассеты собираются на твоей машине из одной твоей DLL
-    4.1.x: в лаунчере кнопка *FSR 4.1.1 из своей DLL AMD → Выбрать DLL…* (2–5 минут, на RDNA4
-    вдвое дольше; нужен свежий Proton), или `tools/fsr4cap`.
-  - Быстрее шейдеров самой AMD на RDNA3: финальные проходы FSR 4 и 4.1.1 переписаны с записью
-    через shared-память (в 3.5 и 2.3 раза быстрее, побитово так же); FSR 4 в 4K на RX 7800 XT
-    стоит ~4 мс вместо ~6.
-- **Многопоточная обработка GPU-команд.** Поток команд PS4 разбирается в одном потоке, а
-  привязка ресурсов и запись draw — в другом (двухстадийный конвейер), плюс отдельный поток
-  записи команд Vulkan и вспомогательные потоки для копий памяти. В начале проекта единственный
-  поток GPU ограничивал игру ~26 FPS; сейчас 90–150 FPS в зависимости от разрешения и сцены.
-- **Настройки в меню самой игры:** *Система → Изображение / Эффекты* (после *Экран/звук*) — их
-  строит и рисует сама игра: разрешение вывода, апскейлер, пресет, резкость, счётчик FPS,
-  детализация моделей и эффекты игры, на языке игры.
-- **Меню поверх игры** (Insert или L3+R3) в стиле диалогов игры: всё то же и расширенные
-  настройки; геймпад, клавиатура и мышь.
-- **Лаунчер на GTK4** и **AppImage** для Steam Deck.

-## Чем отличается от shadPS4
-
-| | shadPS4 | bbport |
-|---|---|---|
-| Охват | Универсальный эмулятор PS4, много игр | Одна игра: Bloodborne v1.09 |
-| Загрузка | Свой ELF-загрузчик и эмуляция ядра во время работы | eboot заранее превращается (`scripts/`) в образ с прилинкованными libc/Fios2 PS4; загрузчик на C отображает его и передаёт управление игре (загрузчик и рантайм — ~5 тыс. строк) |
-| Память | Вид памяти PS4 со стороны GPU хранится копиями в VRAM, синхронизация через отслеживание записей защитой страниц | По умолчанию та же модель (как в 0.3); в режиме *Новая модель памяти и трансляции*: память игры в оперативной памяти, GPU использует её на месте, часто читаемое — в VRAM, освобождается, когда не нужно |
-| Командный процессор | Эмулируется: записи в память, DMA и метки выполняет процессор во время разбора команд | По умолчанию так же; в новом режиме переводится в команды Vulkan, их выполняет видеочип в порядке потока, метки — после реального завершения работы |
-| Системные библиотеки | Широкий HLE ОС PS4 | Небольшой рантайм (`src/runtime_*.c`) ровно под то, что вызывает Bloodborne: память, потоки, синхронизация, файлы, звук (включая ATRAC9), геймпад, сохранения, AppContent |
-| GPU | Видеоядро и рекомпилятор шейдеров shadPS4 | То же ядро (вложено, GPL) с ~200 помеченными правками (`bbport:`) и новыми модулями: двухстадийный конвейер draw, мемоизация состояния прохода и наборов текстур, уменьшенные цели сцены, векторы движения, FSR 3.1/4/4.1.1, захват кадра, профайлер GPU |
-| Поток GPU | Один поток обрабатывает весь поток команд (узкое место в Bloodborne) | Разбор и запись draw идут в разных потоках; работа масштабируется под число потоков (в том числе Steam Deck) |
-| Апскейлинг | — | Временной (FSR 3.1, FSR 4, FSR 4.1.1) на собственных векторах движения и jitter игры |
-| Патчи игры | Патч-файлы применяет эмулятор | Те же патчи сообщества компилируются при запуске (`scripts/patches.py`); разрешение рендера, эффекты и FPS — из лаунчера |
-
-Без shadPS4 bbport бы не было: его рендерер и рекомпилятор шейдеров — основа графической части.
-
-### Wine + DXVK для одной игры
-
-- **Процессор.** Процессор PS4 — x86-64, поэтому код игры выполняется прямо на процессоре ПК, без
-  эмуляции и перевода инструкций.
-- **Системные библиотеки.** Как Wine подменяет Windows API, так рантайм bbport (`src/runtime_*.c`)
-  реализует ровно те функции ОС PS4, которые вызывает Bloodborne: память, потоки, файлы, звук,
-  геймпад, сохранения.
-- **Память.** В новом режиме — как у игры для ПК: данные игры в оперативной памяти, видеопамять
-  используется так, как её использует игра для ПК. Пока режим экспериментальный.
-- **Графика.** Поток команд видеочипа PS4 (PM4) — это записанные вызовы графического API игры:
-  его пишут 99 функций статически слинкованной libGnm, так что разбор потока и перевод самих
-  вызовов дают одно и то же. Шейдеры GCN переводятся в SPIR-V. В новом режиме работа командного
-  процессора (записи в память, DMA, метки) тоже переводится в команды Vulkan; метки пишет сам
-  видеочип. Дескрипторы ресурсов (текстур, буферов) транслятор читает на процессоре, как DXVK
-  читает привязки ресурсов: текстуру PS4 нужно перевести из раскладки PS4 в образ Vulkan до
-  отрисовки, поэтому процессор должен знать её дескриптор заранее — это трансляция, а не
-  эмуляция. Таблицы дескрипторов (дампы движка констант) читает только транслятор, поэтому их
-  выполняет процессор. Occlusion-запросы игры (~60 за кадр) — настоящие запросы Vulkan; предикация, `COPY_DATA`,
-  `COND_EXEC` тоже переводятся (проверка — `BB_PM4_SELFTEST=1`).
-  Подробно — [docs/EMULATION_REMOVAL_PLAN.ru.md](docs/EMULATION_REMOVAL_PLAN.ru.md), «Шаг 4».
-
-«Порт» здесь — сборка под одну игру, а не переписанный исходный код: исходного кода игры у
-проекта нет, и он его не содержит.
-
-## Требования
-
-- Linux x86-64, видеокарта с Vulkan 1.3. Проверено: AMD RX 7800 XT, Mesa 26 (RADV).
-  Режим *Новая модель памяти и трансляции* на NVIDIA пока не проверен.
-  FSR 4 / 4.1.1 требуют shader Float16, Int8/Int16, целочисленных dot-произведений,
-  linear compute derivatives и extended storage image formats; FSR 4.1.1 дополнительно
-  требует `VK_VALVE_shader_mixed_float_dot_product`. Неподдерживаемый вариант заменяется
-  на FSR 3.1 до первого кадра и недоступен в игровом меню.
-- Свой расшифрованный дамп игры: папка `CUSA03173` (eboot.bin, sce_module, ...), версия 1.09.
-  Дамп обновления — отдельная папка: скопируйте её поверх базовой игры с заменой файлов. Одна
-  базовая игра (1.00) падает при запуске (guest offset 0x20348b8); лаунчер и `run.sh` проверяют
-  исполняемый файл и пишут, чего не хватает (`BB_SKIP_GAME_CHECK=1` отключает проверку).
-  Другие издания (американское `CUSA00900`, азиатское `CUSA03023`, ...) запускают тот же
-  исполняемый файл 1.09. В некоторых дампах в него уже вшит патч 60 FPS от Lance McDonald, из-за которого игра
-  падает при открытии меню жестов: проверка тогда просит чистый eboot.bin (у bbport свои 60 FPS).
-- Для сборки: GCC, CMake, Ninja, Python 3, glslang, SDL3, заголовки Vulkan и библиотеки из
-  `shell.nix`. С [Nix](https://nixos.org) всё берётся из `shell.nix` автоматически.
-
-## Сборка и запуск
-
-```bash
-git clone --recursive https://github.com/deadinside28/bloodborne_pc.git bbport && cd bbport
-bash build.sh                        # собирает out/bb-probe и out/gpu/libbbgpu.so
-BB_GAME_DIR=/путь/к/CUSA03173 bash run.sh
-```
-
-или через лаунчер (выбрать папку игры, настройки, «Запустить»):
-
-```bash
-bash launcher/bb-launcher.sh         # launcher/install-desktop.sh добавит его в меню приложений
-```
-
-По умолчанию папка игры ищется рядом с репозиторием (`../CUSA03173`). Сохранения и кэш шейдеров
-— в `user/` (в лаунчере можно выбрать другую папку и импортировать сохранения из shadPS4,
-другого порта или выгруженные с PS4 без шифрования; текущие сначала копируются в
-`user/savedata-backups/`; `scripts/save_import.py`), настройки — в `bbport.ini`. Геймпад через
-SDL3 (если их несколько, нужный выбирается в лаунчере: *Управление → Контроллер*,
-`BB_GAMEPAD=<GUID или часть имени>`; если не выбран, управляет тот, на котором нажали кнопку или
-двинули стик). Клавиатура тоже работает, и при подключённом геймпаде
-(на Steam Deck он есть всегда); обе раскладки меняются в лаунчере (*Управление*). Имя персонажа
-вводится с клавиатуры в окне поверх игры. Тачпад: левая половина (Tab, Back/Select) открывает
-жесты, правая (Backspace) — личные вещи. На геймпаде без тачпада (Xbox) Back + крестовина
-влево / вправо нажимает левую / правую половину. В лаунчере (*Управление*) можно поменять стики
-местами и инвертировать камеру геймпада (`pad_swap_sticks`, `pad_invert_look_x`, `pad_invert_look_y` в bbport.ini). *Прямая камера мышью*
-(`mouse_camera=direct`): мышь поворачивает камеру сама, 1:1, без мёртвой зоны и кривой стика (код
-игры 1.09 перехватывается, пока окно держит мышь; при захвате цели мышь снова двигает стик). PSN нет: экран «Играть по сети / вне сети» пропускается,
-игра сразу открывает главное меню вне сети (патч игры; в лаунчере *Эффекты игры → Пропускать
-выбор «по сети / вне сети»*, `BB_SKIP_NETWORK_CHOICE=0` — показывать). При нескольких мониторах нужный выбирается в
-лаунчере: *Экран → Монитор* (`BB_DISPLAY=<номер или часть имени>`).
-
-**Смена разрешения и пресетов:** для вывода не 1080p (720p на Steam Deck, 1440p, 4K) вся игра
-рисуется в разрешении пресета, которое задаёт патч при запуске, — это самый быстрый путь.
-Смена вывода или пресета в игровом меню тогда требует «Применить и перезапустить игру».
-Настройка «Смена разрешения на лету» (лаунчер, игровое меню, `bbport.ini`
-`live_resolution=0|1|auto`; **по умолчанию выключена**) вместо этого оставляет игре 1080p и
-масштабирует её цели на ходу: 720p/1080p/1440p/4K и пресеты меняются без перезапуска. Это
-дороже: игра считает, что рисует 1080p, и рисует больше (например, мелких источников света
-примерно в 8 раз больше), часть целей копируется между размерами — включай только на мощных
-настольных видеокартах (`auto` включает её на дискретных GPU с 8+ ГБ, кроме NVIDIA старше
-Turing). Вывод 1080p и TAA всегда идут живым путём.
-
-**TAA:** отдельный пункт сглаживания в лаунчере и игровом меню, переключается на ходу.
-Работает в разрешении вывода без модели FSR; пресет FSR сохраняется для обратного
-переключения. Native AA у FSR выполняет реконструкцию поверх полного разрешения и
-может быть тяжелее выключенного сглаживания. TAA тоже добавляет обработку кадра.
-
-**Моды:** лаунчер подключает распакованные моды из отдельных папок (с `dvdroot_ps4/`, с лишней
-папкой-обёрткой или сразу с папками игры вроде `chr/`; регистр имён не важен), с переключателями
-и порядком загрузки. **Сторонние патчи:** XML-файлы в формате shadPS4 в папке `patches/` каталога
-данных, включаются в лаунчере. Подробнее — [моды и патчи](docs/MODS.md).
-**DLC:** дампы дополнений клади в `user/addcont/<title id>/<метка>/` (как в shadPS4, например
-`user/addcont/CUSA03173/SPEXPANSIONDLC03` для The Old Hunters): каждая такая папка сообщается
-игре как установленное дополнение.
-
-**Язык лаунчера:** русский, английский, бразильский португальский или упрощённый китайский (по умолчанию — как в системе).
-
-**Свободная камера и debug menu игры** (v1.09): включи соответствующие галочки в лаунчере
-или игровом меню и перезапусти игру. Для камеры используется
-[патч Lance McDonald из GoldHEN](https://github.com/GoldHEN/GoldHEN_Patch_Repository/blob/main/patches/xml/Bloodborne-Orbis.xml):
-удерживай Cross и нажимай L3 для переключения режимов (клавиатура: Space + Z).
-Камере шрифты не нужны; с патчем Enemy Control она несовместима.
-Для debug menu сначала установи `DbgFont14h.ccm` и `DbgFont14h.tpf` из
-[Debug Menu and XML Patch](https://www.nexusmods.com/bloodborne/mods/253) в
-`dvdroot_ps4/font/` внутри папки игры. Если файлов нет или они пустые, запуск остановится
-с объяснением. Меню открывается левым touchpad / Tab (с включённым debug menu левая половина
-больше не открывает жесты); правый touchpad — Backspace.
-Координаты касания передаются с SDL-геймпадов; Back/Select заменяет левый клик на геймпадах
-без сенсорной поверхности. Меню настроек порта по-прежнему открывается Insert / L3+R3.
-
-GPU-запросы occlusion пока возвращают искусственные счётчики пикселей
-(`PixelPipeStatDump`), а `IT_SET_PREDICATION` не реализован. Свободная камера позволяет
-проверять видимость, но не добавляет GPU occlusion culling.
-
-**Ассеты апскейлеров** (в репозитории их нет; FSR 3.1 они не нужны):
-
-```bash
-bash tools/fetch_fsr4_assets.sh      # FSR 4 v07 (MIT, собраны Q2RTX из исходников AMD)
-# FSR 4.1.1 — из своих DLL AMD (например, FSR4_LATEST у OptiScaler), нужен GE-Proton 10 или новее:
-bash tools/fsr4cap/build_assets.sh <amd_fidelityfx_upscaler_dx12.dll>
-```
-
-**FSR 4.1.1 из своей DLL.** Проще всего — в лаунчере: *Апскейлер → FSR 4.1.1 из своей DLL AMD →
-Выбрать DLL…* и указать `amd_fidelityfx_upscaler_dx12.dll` версии 4.1.x: из папки `FSR4_LATEST`
-OptiScaler или из игры с FSR 4.1. Этого одного файла достаточно: DLL AMD сама экспортирует
-FidelityFX API, загрузчик не нужен (через `amd_fidelityfx_loader_dx12.dll` записывалась бы только
-DLL без этих функций, и тогда лаунчер его спросит). DLL проверяется сразу, без долгой записи, и не подходят: официальная FSR 4.0.x
-(например, 4.0.3 из Pragmata — AMD включает её только на RDNA4, под Proton на других видеокартах
-она не запускается) и сборки сообщества (4.0.2b, 4.1.1b и подобные INT8-сборки OptiScaler:
-другая модель и число проходов). Дальше DLL запускается под Proton и записывается в 20
-разрешениях (ход виден в строке и во вкладке «Журнал»; на RDNA4 — второй раз, для варианта FP8), проходы переводятся в SPIR-V, и FSR 4.1.1
-сразу выбирается. Proton выбирается сам — первый, под которым DLL включает FSR 4.1: GE-Proton 10
-или новее, Proton-CachyOS, Proton Experimental (проверено: GE-Proton 11, Proton-CachyOS 11,
-Experimental от октября 2026; Proton 11.0 из Steam и GE-Proton 9 — нет). Он запускается в
-рантайме Steam, который требует (Steam ставит его при первом запуске любой игры с этим Proton),
-или через umu-launcher, если он установлен. На NixOS umu-launcher берётся из `nix-shell` (в первый
-раз скачивается, ~1,7 ГБ); AppImage запускает запись на самой системе, через systemd пользователя
-(`systemd-run --user`), так как системный `/nix` ей не виден. Запись на Steam Deck пока не проверена; если DLL не включит
-там FSR 4.1, собери на ПК и скопируй папку `fsr4_411`. То же из командной строки:
-`--build-fsr411 <DLL>` у лаунчера (и у AppImage).
-
-**DLSS (NVIDIA GeForce RTX).** SDK DLSS от NVIDIA не входит в репозиторий: скачай
-[github.com/NVIDIA/DLSS](https://github.com/NVIDIA/DLSS) (достаточно `include/` и
-`lib/Linux_x86_64`) и собери с `DLSS_SDK_ROOT=/путь/к/DLSS bash build.sh`. Тогда собирается и мост
-`out/libbbport_dlss.so` (`gpu/dlss_bridge`, единственный код, использующий SDK), а
-`libnvidia-ngx-dlss.so.<версия>` от NVIDIA копируется рядом с `out/bb-probe`; остальное даёт
-драйвер. Затем выбери *DLSS* в лаунчере или во внутриигровом меню: пресет задаёт разрешение
-рендера, Native AA — это DLAA. DLSS получает те же входы, что и FSR 3.1 (цвет сцены, глубину,
-векторы движения, jitter). Без библиотек, на других видеокартах или с `BB_DLSS=0` он недоступен,
-а выбранный DLSS заменяется на FSR 3.1.
-
-На Linux DLSS также нужен CUDA/UVM из драйвера NVIDIA. Если устройство не создаётся с
-расширениями DLSS, рендерер повторяет попытку без них и использует FSR 3.1. Если отсутствует
-`/dev/nvidia-uvm`, загрузи установленный модуль командой `sudo modprobe nvidia_uvm` и перезапусти
-игру. Пакет `nvidia-modprobe` из репозитория дистрибутива позволяет библиотекам NVIDIA загружать
-модуль по мере необходимости.
-Если при включённом Secure Boot команда `modprobe` сообщает `Key was rejected by service`,
-зарегистрируй ключ подписи модуля по [процедуре MOK своего дистрибутива](https://documentation.ubuntu.com/security/security-features/platform-protections/secure-boot/#mok-generation-and-signing-process).
-
-AppImage, собранный с `DLSS_SDK_ROOT`, содержит мост и библиотеку NVIDIA (лицензия RTX SDK от NVIDIA
-это разрешает в составе приложения; её текст — `NVIDIA-DLSS-LICENSE.txt` в пакете). Более новая
-`libnvidia-ngx-dlss.so.<версия>` (из `lib/Linux_x86_64/rel` в SDK) выбирается в лаунчере:
-*Апскейлер → DLSS: библиотека NVIDIA → Выбрать файл…*, как DLL для FSR 4.1.1; она копируется в
-`<user>/dlss/`, и игра берёт её первой. `nvngx_dlss.dll` из игр — библиотека для Windows: драйвер
-NVIDIA на Linux её не загружает.
-
-Скрипт из исходников берёт инструменты из системы (MinGW GCC, CMake, Ninja, Python 3,
-SPIRV-Tools, Git) или из Nix; в AppImage они уже собраны.
-
-**FP8 на RDNA4.** Когда vkd3d-proton даёт кооперативные матрицы FP8 (RDNA4), DLL запускает
-другой вариант своих проходов: другие шейдеры и веса, другие размеры диспатчей. Сборка
-записывает оба: INT8 в `fsr4_411/`, FP8 в `fsr4_411/fp8/`, а игра сама выбирает FP8, если у
-видеокарты есть матрицы FP8 (`VK_EXT_shader_float8`); в журнале — `Upscaler: FSR 4.1.1 replay,
-FP8 …`. `BB_FSR411_VARIANT=int8` — принудительно INT8. Проверено на RX 7800 XT через эмуляцию FP8
-на FP16 в vkd3d-proton (`BB_FSR4CAP_FP8=1` записывает его и там, `fp8emu/`): побитово как DLL;
-**на самой RDNA4 ещё не запускалось.**
-
-**AppImage** (Steam Deck): `bash build.sh && bash packaging/appimage.sh` →
-`dist/Bloodborne-bbport-x86_64.AppImage`; данные в `~/.local/share/bbport`, `--play` запускает
-игру без окна лаунчера (игровой режим). Модели FSR 4.1.1 в пакет не входят: собери их кнопкой
-лаунчера (см. выше), они лягут в `~/.local/share/bbport/fsr4_411` (`BB_PACKAGE_FSR411=1` кладёт
-локальную `fsr4_411` в AppImage для своих устройств). На Steam Deck выбирай вывод 1280×720 (игра 16:9, на
-экране 1280×800 будут узкие полосы).
-
-**Добавление AppImage в Steam** («Добавить стороннюю игру»): ничего настраивать не нужно,
-инструмент совместимости не важен. (Steam подгружает свой оверлей во все сторонние игры; AppImage
-убирает его до запуска своих программ, поэтому оверлея Steam в игре нет.) Если Steam запускает игры без FUSE (NixOS: FHS-песочница Steam; AppImage тогда завершается с
-*Cannot mount AppImage*), в параметрах запуска укажи
-
-```
-TMPDIR=$HOME/.cache APPIMAGE_EXTRACT_AND_RUN=1 NO_CLEANUP=1 %command%
-```
-
-Тогда AppImage при первом запуске распакуется (~2 ГБ, `~/.cache/appimage_extracted_*`, ~10 с),
-а дальше будет запускать эту копию; новая версия AppImage распакуется заново, старую копию можно
-удалить. Без `TMPDIR` распаковка шла бы в `/tmp` Steam, а он там в оперативной памяти.
-` --play` после `%command%` — запуск без лаунчера.
-
-**NVIDIA в AppImage:** пакет автоматически ищет установленный на машине 64-битный NVIDIA
-Vulkan-драйвер и подключает его вместе с комплектными AMD/Intel-драйверами. Используются
-библиотеки NVIDIA с этой машины, чтобы их версия совпадала с модулем ядра. На обычных Linux
-дистрибутивах они доступны в `/usr/lib*`; на NixOS внутренний `/nix/store` AppImage может скрывать
-драйвер хоста. В этом случае библиотеки NVIDIA нужно скопировать в доступную папку и указать
-`BB_NVIDIA_LIB_DIR=/путь/к/библиотекам` (манифест NVIDIA тоже должен быть доступен).
-С драйвером NVIDIA хоста AppImage передаёт и файлы EGL-вендоров хоста, NVIDIA первым
-(`__EGL_VENDOR_LIBRARY_FILENAMES`; без них ICD NVIDIA на некоторых системах не отдавал
-`vkCreateInstance`, #107; `BB_NVIDIA_EGL=0` — выключить). Явные `VK_DRIVER_FILES`/`VK_ICD_FILENAMES` сохраняются. Проверка драйвера внутри пакета:

-## Что будет дальше
-
-- Новая модель памяти и трансляции по умолчанию и на NVIDIA, когда она станет там не медленнее;
-  после этого старая модель удаляется.
-- Текстуры — объекты, которые создаются при загрузке (меньше угадывания по адресам, загрузка
-  вне кадра).
-- Шейдеры переводятся заранее, при установке, а не во время игры.
-- Больше параллельности CPU в обработке GPU-команд (дальнейшее разделение стадии записи draw)
-  с масштабированием на все потоки — важнее всего для Steam Deck.
-- Async compute для апскейлера (в 4K кадр упирается в GPU).
-- XeSS (суперразрешение) и генерация кадров XeFG через помощник под Wine с общей памятью Vulkan
-  (прототип моста памяти — `tools/bridge_helper`); входы апскейлера
-  в виде, совместимом с подходом OptiScaler.
-- Генерация кадров (сначала FSR 3.1 FG), маски реактивности и прозрачности для частиц и тумана.
-- Исправление гонок в шейдерах FSR 4.1.1 от AMD при ширине вывода, не кратной 64 (например,
-  1600×900) — так же, как уже исправлена гонка у левого края в FSR 4 v07 при 1080p.
-- Проверка AppImage на Steam Deck; вывод HDR.

                             Preamble
 
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
+  The GNU General Public License is a free, copyleft license for

+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
 your programs, too.
 
   When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
 
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
 
   For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
 
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
 
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
 
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
 
   The precise terms and conditions for copying, distribution and
 modification follow.
 
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+                       TERMS AND CONDITIONS
 
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
+  0. Definitions.
 
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
+  "This License" refers to version 3 of the GNU General Public License.
 
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
 
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
 
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
 
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
 
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
 
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
 
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
 
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
+  1. Source Code.
 
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
 
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
 
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
 
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
 
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
 
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
+  The Corresponding Source for a work in source code form is that
+same work.
 
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
+  2. Basic Permissions.
 
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
 
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
 
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
 this License.
 
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
 
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
+  13. Use with the GNU Affero General Public License.
 
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
 
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
+  14. Revised Versions of this License.
 
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.

+the GNU General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
 
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
 
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's

+to choose that version for the Program.

 ## Features
 
-- **Online play (beta)** through [The Hunter's Dream](https://thehuntersdream.com): messages,
-  bloodstains, ghosts, bells and summons, with bbhost's players and Windows players of bbport, or
-  with your group on [a server of your own](docs/SERVER.md).
-- **Upscaling:** AMD FSR 3.1, FSR 4 and FSR 4.1.1, **NVIDIA DLSS** on GeForce RTX, and
-  native-resolution TAA.
-- **Unlocked frame rate**, capped at your display's refresh rate up to 120 FPS (above that the
-  game's own movement timing breaks), or 30/60/90 FPS. Output from 720p to 4K.
-- **Launcher** with every setting in one window, in English, Spanish, Italian, French, German,
-  Portuguese, Russian and Simplified Chinese, like the in-game menu (Insert or L3+R3).
-- **Settings in the game's own System menu** as well (Display and Effects pages), in the game's
-  language.
-- **Two memory models:** the new one, where the GPU works with the game's memory as in a PC game
-  (the default on AMD), and the one of 0.3 (the default elsewhere); the launcher switches them.
-- **Xbox, Switch and keyboard button prompts**, picked by the controller in use, and a gestures
-  menu without the motion-control icons.
-- **Cheats and gameplay tweaks:** never die, stealth, silent steps, enemy control, camera
-  distance, ragdoll physics and more.
-- **Trophies:** a notice in the game, in the style of the PS4's, and a Trophies page in the
-  launcher with every trophy, from your own dump. Their names and descriptions need the PS4's
-  trophy key (shadPS4's TrophyKey), which you enter in the launcher; without it, only the icons.
-- **Game effects** on and off, **mods** and community **patches**, loaded without changing the
-  game files ([how](docs/MODS.en.md)).
-- **Add to Steam** in one click (native or Flatpak Steam), and **Discord Rich Presence** with the
-  area you are in and your co-op partners.
-- **AppImage:** one file with everything inside, for any distribution and the Steam Deck. It
-  updates itself: the launcher's **About** page checks this repository's releases and installs
-  a new AppImage over the old one, or any earlier release from 0.5-linux.1 on, to go back to one
-  that worked better.
+- **Multiplayer**: online messages, bloodstains, ghosts, bells and summons, on
+  [The Hunter's Dream](https://thehuntersdream.com) or a server of your own; **Seamless Co-op**
+  (experimental), co-op that lasts through deaths, lamps and areas, for up to 5 hunters; and
+  **local co-op** (split screen), 2 to 4 players on one PC, each with their own controller.
+- **In-game map** (Hunter's Atlas): a fullscreen map with where you are, lamps and items, and fast
+  travel to the lamps you've found.
+- **Frame rate unlocked** (up to 120 FPS recommended; the game's movement can break above it)
+  or capped at **30, 60 or 90**, and changed while you play from the in-game menu. Resolutions from
+  **720p to 4K**, and any **aspect ratio** (4:3 to 32:9 ultrawide, [how](docs/TROUBLESHOOTING.md#the-picture-is-stretched-on-an-ultrawide-screen)).
+- **Upscaling:** AMD **FSR 3.1** and **FSR 4**, NVIDIA **DLSS** (GeForce RTX) and TAA, and
+  **frame generation** (FSR 3.1, or DLSS on GeForce RTX 40 and newer).
+- **Any controller:** PlayStation, Xbox and Switch pads with their own **button prompts in the
+  game**, and **keyboard and mouse**, with keys you can rebind (bbport 0.7's Dark Souls
+  III-style layout, or the classic one of earlier Linux versions), movement keys that keep a
+  sprint through turns (the last of two opposite keys wins; `keyboard_movement=0.7` in
+  `bbport.ini` for bbport 0.7's ramped stick) and the mouse as a pointer in the game's menus.
+- **Exit to desktop** from the game's title and System menus.
+- **Cheats and gameplay tweaks:** never die, stealth, camera distance, ragdoll physics and more.
+- **Trophies and the platinum**, with a notice in the game like on the PS4.
+- **Add to Steam** in one click, and **Discord Rich Presence** with your area, your co-op
+  partners and a button to this repository.
+- **Launcher and in-game menu** (Insert, or hold L3 + R3) in English, Spanish, French, German, Italian,
+  Portuguese, Russian and Simplified Chinese.
+- **AppImage** ready for any distribution and the Steam Deck, which **updates itself** from the
+  launcher (and can go back to an earlier release).
+- **Mods and community patches**, without touching the game files ([how](docs/MODS.en.md)).
 
 ## Requirements
 
-- Linux x86-64 and a GPU with Vulkan 1.3: AMD or Intel with Mesa, or NVIDIA with NVIDIA's driver
-  (open kernel modules included). Mesa's NVK has not been tested.
-- DLSS needs a GeForce RTX (20 series or newer) and NVIDIA's driver; it does not work with NVK.
-- About 6 GB of free memory, 10 GB for 1440p or 4K output.
+- Linux x86-64 and a GPU with Vulkan 1.3: AMD or Intel with Mesa, or NVIDIA with NVIDIA's driver.
+- About 6 GB of free memory, 10 GB for 1440p or 4K.
 
 ## Getting started
 
-### AppImage
+1. Download `Bloodborne-bbport-x86_64.AppImage` from the
+   [latest release](https://github.com/ayozetr/bloodborne_linux/releases/latest).
+2. Make it executable and run it.
+3. Choose your game folder (the one with `eboot.bin`) and press **Play**.
 
-Build it with `bash build.sh && bash packaging/appimage-sharun.sh`, then run
-`dist/Bloodborne-bbport-x86_64.AppImage`. Choose your game folder (the one with `eboot.bin`) and
-press **Play**. Saves and settings go to `~/.local/share/bbport`.
+Saves and settings go to `~/.local/share/bbport`; **Setup → Saves** exports your saves into a
+.zip and imports them back, or from shadPS4, and can keep a copy of them from before each game
+(off by default). The Game of the Year edition already has The Old
+Hunters; with the base game, its DLC goes in **Setup → DLC folder** ([how](docs/COMPATIBILITY.md)).
 
-### From source
+## Online play
+
+In the launcher's **Multiplayer → Online** tab, turn on **Play online**, choose a server and press **Test**
+in the **Status** row (every line should get a check mark):
+
+- **Seamless Hunt** (the default): the community server of Seamless Co-op (BBSC), with players on
+  the Windows port. Make an account from the launcher with **Create** ([docs/ONLINE.md](docs/ONLINE.md#seamless-hunt)).
+- **The Hunter's Dream**: sign in with Discord. You play with bbhost's players
+  ([docs/ONLINE.md](docs/ONLINE.md#the-hunters-dream-with-bbhosts-players)).
+- **Your own server**: for your group, with Docker and Tailscale ([docs/SERVER.md](docs/SERVER.md)).
+- **Seamless Co-op (BBSC)**, in the same tab: every player needs it, and summons across areas need
+  its game server, which your own server can run ([docs/ONLINE.md](docs/ONLINE.md#seamless-co-op-bbsc)).
+
+With online play on, the game starts online by itself, as PLAY ONLINE on a PS4. If you turned off
+*Skip the “play online / offline” choice* and pick offline, choose **Log In** on the title screen later
+for online play; until then the co-op bells are greyed out.
+
+Everyone in a session needs update 1.09. Turn cheats off when you play with others. Ports,
+firewalls and the rest: [docs/ONLINE.md](docs/ONLINE.md).
+
+## Local co-op (experimental)
+
+Several games on one PC, one per player, each in its part of the screen with its own controller
+(the launcher's **Multiplayer → Local** tab): choose the players (2 to 4), the layout and each player's
+controller, then press **Play together**. Player 1 plays with the launcher's settings and saves;
+players 2 to 4 get their own saves and settings in `~/.local/share/bbport/coop/player<N>` (copied
+from player 1's the first time, about 400 MB each), without online play or Discord. One player can
+use the keyboard and mouse. Only player 1 has sound unless you turn that off. The windows can go
+to a monitor of their own (**Monitor**), and **Copy player 1's saves** gives another player the
+same characters (their own saves are backed up first). The windows are placed through X11, which
+works in a Wayland session too (XWayland).

-### Online play
+## On Windows
 
-1. In the launcher, open **Online**, turn on **Play online** and choose the co-op server:
-   - **The Hunter's Dream (with bbhost players)**: sign in with Discord, or create an account
-     with just a name and keep the recovery code it shows (it brings the account back on
-     another PC). [bbbridge](bbbridge/README.md) by MaskZeus runs with the game and talks to
-     The Hunter's Dream the way bbhost does, so you play with bbhost's players and with Windows
-     players of bbport on the same pool.
-   - **Your own server**: your group's shadNet server and your account on it
-     ([docs/SERVER.md](docs/SERVER.md), Docker and Tailscale; tested with a Linux and a Windows
-     player).
-2. **Test the connection**: every line should be green.
-3. Start the game and choose online at the title screen.
-
-**Seamless co-op (experimental)**: turn on **Seamless co-op (BBSC)** in the Online page and the
-session lives through deaths, lamps, areas, bosses and the Hunter's Dream, with up to 5 hunters.
-It is [BBSC](https://github.com/Classmg22/BBSC) by CLS_AMG, built for Linux here; every player of
-the session needs it (on Windows, BBSC's package for the Windows port). Summons across areas need
-BBSC's game server ([docs/ONLINE.md](docs/ONLINE.md#seamless-co-op-bbsc)).
-
-Everyone in a session needs game version 1.09 and the same pool. Turn cheats off when you play
-with others. shadPS4's public shadNet server no longer accepts bbport builds: it signs them out
-right after the login, and the launcher says so.
-
-With your own server, co-op connects the players directly over UDP. UPnP opens the port on the router by itself; with
-ufw or firewalld on, the launcher's **Online** page says so and gives the commands: pin the
-**Co-op port** (for example 3658), open it (`sudo ufw allow 3658/udp`), and for UPnP let the
-router's answers in (`sudo ufw allow from <router> proto udp`). [More in docs/ONLINE.md](docs/ONLINE.md).
-
-### DLSS
-
-On a PC with a GeForce RTX, run `bash tools/build_dlss.sh` once after `build.sh`. It downloads
-what it needs from the NVIDIA DLSS SDK and builds the bridge. Then choose **DLSS** as the
-upscaler.
-
-### Environment variables
-
-The launcher's **Settings → Developer → Extra variables** field (`NAME=value`, space-separated)
-passes environment variables to the game, the same ones `run.sh` takes from a terminal. Every one
-the port reads, what it does and which win over which: [docs/ENVIRONMENT.md](docs/ENVIRONMENT.md).
-
-### DLC
-
-The Game of the Year edition (`CUSA03173`) already includes The Old Hunters. With the base game
-(such as the US `CUSA00900`), dump your add-ons too: each one is a folder (`SPEXPANSIONDLC03`,
-`SPDLCMESSENGER00`…) with only `sce_sys` inside, because their data ships with the 1.09 update.
-Put them in one folder and pick it in the launcher (**Game → DLC folder**), or set
-`BB_DLC_DIR=/path/to/dlc` for `run.sh`; the launcher shows how many it found. Each folder must
-keep the add-on's name (its entitlement label, such as `SPEXPANSIONDLC03`). Copying them to
-`user/addcont/<title id>/`, shadPS4's layout, works too.
-
-### Add to Steam
-
-**Game → Add to Steam** puts Bloodborne in your Steam library; it starts with the launcher's
-settings. Steam has to be closed while the game is added, and the launcher offers to do that.
-Flatpak Steam runs games inside its sandbox, which has neither the game nor your drivers, so
-the shortcut starts the game outside it with `flatpak-spawn --host`. That needs the
-`org.freedesktop.Flatpak` permission for Steam, which the launcher asks for once: it lets Steam
-start programs on your system.
-
-### Button prompts
-
-The game shows PlayStation buttons. In the launcher, **Controls → Button prompts** switches them to
-Xbox, Nintendo Switch or keyboard ones; *Automatic* follows the controller in use, and the
-keyboard's when none is connected. Keyboard prompts show the keys bound in **Controls →
-Keyboard**. **Gestures menu without motion-control icons** cleans up the gestures menu. The
-prompts are put into your own game's menu files at each start, and nothing in the game folder
-changes.
+If you need a Windows version, I recommend
+[Supermedo's Windows port](https://github.com/Supermedo/bloodborne_pc) and
+[Awakenchan's LanternEngine](https://github.com/Awakenchan/LanternEngine).
 
 ## Support
 
-If this fork is useful to you and you would like to support it, you can on
-[Ko-fi](https://ko-fi.com/ayozetr). The port itself is deadinside28's work (see below).
+This fork is built on the port deadinside28 created, but it has a lot of hours of work behind it,
+and above all hours and hours of testing things and hunting down fixes so it runs as well as it
+can. I always try to fix every report as soon as possible, because I know how much this game means
+to some people. If it's useful to you and you'd like to support it, you can on

-# Changelog
-
-## 0.3.2 - 2026-10-12
-
-- **Fix: "Failed to acquire Bloodborne server information" after closing
-  bbbridge.** The file that sends the game's server traffic to bbbridge
-  (`host_overrides.custom.json` in bbport's user folder) now exists only while
-  bbbridge runs with the switch on The Hunter's Dream: it goes when bbbridge
-  closes, when the bridge stops, or when bbport is set back to shadNet - also
-  in the bbport launcher itself. One left behind by an older bbbridge
-  (including the Python 0.2.0) is cleaned up the next time bbbridge starts.
-- Troubleshooting notes in the README.
-
-## 0.3.1 - 2026-10-12
-
-- **Online switch** in place of the "Route bbport through bbbridge" box:
-  shadNet on the left, The Hunter's Dream (bbhost) on the right. A line under
-  it says which pool and account PLAY uses.
-- **shadNet comes back whole**: switching to shadNet restores bbport's own
-  server *and* shadNet account (name, password). The Hunter's Dream account is
-  bbport's online id only while switched to it. PLAY follows the switch; on
-  shadNet no Discord sign-in is needed.
-- **Set up by default**: once signed in with Discord, the switch goes to The
-  Hunter's Dream and the live map patch is added; turning either off sticks.
-- **bbport folder**: shows where it was found; bbbridge.exe right next to
-  Bloodborne.exe works too; asks when it had to guess, when a chosen folder is
-  gone, or when bbport is not found.
-- **Clear errors**: PLAY and "bbport settings..." say what is missing (sign-in,
-  game folder, shadNet account, launcher open, missing exe, Windows' error).
-  "bbport settings..." also works before the launcher has any settings.
-- **Lighter**: the window draws at full rate only while used (idle CPU about a
-  quarter of before).
-- **Steadier event poll**: it no longer stalls ~8 s about once a minute, so a
-  summon reaches the game without that delay.
-- Verified live: joining a bbhost host's world as a guest (Small Resonant Bell).
-
-## 0.3.0 - 2026-10-12
-
-- First C++ release: one window for the bridge, Discord sign-in, routing bbport,
-  the live map patch and starting the game.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

-# bbbridge (C++)
-
-Play **co-op with bbhost players** on **The Hunter's Dream** while using
-**bbport** (Supermedo's `bloodborne_pc` for Windows, DLSS / FSR 3.1 / FSR 4).
-
-bbbridge looks like a shadNet server to bbport and talks to The Hunter's Dream
-the way bbhost does: matching (rooms, bells, summons), the P2P traffic between
-the two clients (different packet framing, bbport's signaling handshake,
-The Hunter's Dream's STUN and relay), and the game's own server traffic
-(account token, play log for the live map). bbport itself is not modified.
-
-## Layout
-

-   ├─ bbbridge_config.json   settings (optional)
-   ├─ bbbridge_state.json    your account: token + recovery code - never share it

-
-
-## Using it
-
-1. Put the `bbbridge` folder inside bbport's folder (next to `Bloodborne.exe`)
-   and start `bbbridge.exe` (close the bbport launcher first). bbbridge uses
-   the bbport it sits in; anywhere else it asks which bbport to use
-   (**Change...** picks another one later).
-2. **Sign in with Discord**: the app shows a code and opens The Hunter's Dream;
-   sign in there with your Discord account and approve the code. Your account
-   there (the same one bbhost uses) becomes bbport's online id. No password is
-   stored; the account's token goes to `bbbridge_state.json`.
-3. The **Online** switch goes to **The Hunter's Dream (bbhost)** by itself
-   once you are signed in (and the live map patch is added; untick it if you
-   like).
-4. Press **PLAY**. The app starts the bridge if needed and launches the game
-   with bbport's saved settings. You can also start the game from the bbport
-   launcher - as long as bbbridge is open. Graphics, mods and cheats stay in
-   the bbport launcher (**bbport settings...**) or the in-game menu (Insert).
-
-Move the **Online** switch to **shadNet** to go back to bbport's own shadNet
-co-op pool: bbport gets its own server and shadNet account back (the ones it
-had before; a shadNet account is registered at
-[shadnet.shadps4.net](https://shadnet.shadps4.net) and entered in the bbport
-launcher's *Online co-op*). PLAY follows the switch: right, the bbhost pool
-with your Discord sign-in; left, bbport's own shadNet - no sign-in needed.
-Running bbhost and bbport with the same account at the same time is not
-supported.
-
-## Troubleshooting
-
-- **"Failed to acquire Bloodborne server information" with bbbridge closed**:
-  bbbridge 0.3.1 and older (and the Python 0.2.0) left
-  `user\host_overrides.custom.json` in bbport's folder (bbport's user folder),
-  which sends the game's server traffic to bbbridge even when it is not
-  running. Start bbbridge 0.3.2 or newer once (it removes the file when it is
-  not needed), or delete that file by hand. From 0.3.2 the file exists only
-  while bbbridge runs with the switch on The Hunter's Dream.
-- **Nobody comes when I ring a bell**: a Small Resonant Bell is answered only
-  by a host ringing the Beckoning Bell in the same area, near your level (and
-  the other way round). The live map at
-  [thehuntersdream.com/map](https://thehuntersdream.com/map) shows who is
-  ringing which bell where.
-
-## Building (Visual Studio 2022/2026)
-
-Workload **Desktop development with C++** (MSVC, Windows SDK, CMake tools).
-
-- Visual Studio: *File > Open > Folder...* this folder, pick the **x64 Release**
-  preset, *Build > Build All*. `bbbridge.exe` is copied here, the CLI and the
-  unit tests to `bin\`.
-- Command line (Developer PowerShell):
-  `cmake --preset x64-release` then `cmake --build --preset x64-release`
-
-## Tests
-
-- `bin\bbbridge-unit.exe` - framing, signaling, STUN, protobuf, account id.
-- `python tests\e2e\test_e2e.py` - the bridge exe against a fake bbhost
-  server, a fake STUN/relay server and fake game sockets (no internet).

-// DEAR IMGUI COMPILE-TIME OPTIONS
-// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
-// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
-//-----------------------------------------------------------------------------
-// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
-// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
-//-----------------------------------------------------------------------------
-// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
-// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
-// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
-// Call IMGUI_CHECKVERSION() from your .cpp file to verify that the data structures your files are using are matching the ones imgui.cpp is using.
-//-----------------------------------------------------------------------------

-// (minor and older changes stripped away, please see git history for details)
-//  2024-10-07: DirectX11: Changed default texture sampler to Clamp instead of Repeat/Wrap.
-//  2024-10-07: DirectX11: Expose selected render state in ImGui_ImplDX11_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
-//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-//  2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-//  2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
-//  2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
-//  2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX11_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
-//  2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
-//  2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-//  2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
-//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-//  2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
-//  2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
-//  2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
-//  2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
-//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2024-07-08: Inputs: Fixed ImGuiMod_Super being mapped to VK_APPS instead of VK_LWIN||VK_RWIN. (#7768)
-//  2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
-//  2023-09-25: Inputs: Synthesize key-down event on key-up for VK_SNAPSHOT / ImGuiKey_PrintScreen as Windows doesn't emit it (same behavior as GLFW/SDL).
-//  2023-09-07: Inputs: Added support for keyboard codepage conversion for when application is compiled in MBCS mode and using a non-Unicode window.
-//  2023-04-19: Added ImGui_ImplWin32_InitForOpenGL() to facilitate combining raw Win32/Winapi with OpenGL. (#3218)
-//  2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen. (#2702)
-//  2023-02-15: Inputs: Use WM_NCMOUSEMOVE / WM_NCMOUSELEAVE to track mouse position over non-client area (e.g. OS decorations) when app is not focused. (#6045, #6162)
-//  2023-02-02: Inputs: Flipping WM_MOUSEHWHEEL (horizontal mouse-wheel) value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
-//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-//  2022-09-28: Inputs: Convert WM_CHAR values with MultiByteToWideChar() when window class was registered as MBCS (not Unicode).
-//  2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-//  2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-//  2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-//  2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-//  2022-01-17: Inputs: always update key mods next and before a key event (not in NewFrame) to fix input queue with very low framerates.
-//  2022-01-12: Inputs: Update mouse inputs using WM_MOUSEMOVE/WM_MOUSELEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
-//  2022-01-12: Inputs: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
-//  2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-//  2021-12-16: Inputs: Fill VK_LCONTROL/VK_RCONTROL/VK_LSHIFT/VK_RSHIFT/VK_LMENU/VK_RMENU for completeness.
-//  2021-08-17: Calling io.AddFocusEvent() on WM_SETFOCUS/WM_KILLFOCUS messages.
-//  2021-08-02: Inputs: Fixed keyboard modifiers being reported when host window doesn't have focus.
-//  2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using TrackMouseEvent() to receive WM_MOUSELEAVE events).
-//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-//  2021-06-08: Fixed ImGui_ImplWin32_EnableDpiAwareness() and ImGui_ImplWin32_GetDpiScaleForMonitor() to handle Windows 8.1/10 features without a manifest (per-monitor DPI, and properly calls SetProcessDpiAwareness() on 8.1).
-//  2021-03-23: Inputs: Clearing keyboard down array when losing focus (WM_KILLFOCUS).
-//  2021-02-18: Added ImGui_ImplWin32_EnableAlphaCompositing(). Non Visual Studio users will need to link with dwmapi.lib (MinGW/gcc: use -ldwmapi).
-//  2021-02-17: Fixed ImGui_ImplWin32_EnableDpiAwareness() attempting to get SetProcessDpiAwareness from shcore.dll on Windows 8 whereas it is only supported on Windows 8.1.
-//  2021-01-25: Inputs: Dynamically loading XInput DLL.
-//  2020-12-04: Misc: Fixed setting of io.DisplaySize to invalid/uninitialized data when after hwnd has been closed.
-//  2020-03-03: Inputs: Calling AddInputCharacterUTF16() to support surrogate pairs leading to codepoint >= 0x10000 (for more complete CJK inputs)
-//  2020-02-17: Added ImGui_ImplWin32_EnableDpiAwareness(), ImGui_ImplWin32_GetDpiScaleForHwnd(), ImGui_ImplWin32_GetDpiScaleForMonitor() helper functions.
-//  2020-01-14: Inputs: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD/IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT.
-//  2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
-//  2019-05-11: Inputs: Don't filter value from WM_CHAR before calling AddInputCharacter().
-//  2019-01-17: Misc: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created in a different thread or parent.
-//  2019-01-17: Inputs: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages.
-//  2019-01-15: Inputs: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
-//  2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.

-//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-//  2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
-//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-//  2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
-//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-//  2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-//  2018-01-08: Inputs: Added mapping for ImGuiKey_Insert.
-//  2018-01-05: Inputs: Added WM_LBUTTONDBLCLK double-click handlers for window classes with the CS_DBLCLKS flag.
-//  2017-10-23: Inputs: Added WM_SYSKEYDOWN / WM_SYSKEYUP handlers so e.g. the VK_MENU key can be read.
-//  2017-10-23: Inputs: Using Win32 ::SetCapture/::GetCapture() to retrieve mouse positions outside the client area when dragging.
-//  2016-11-12: Inputs: Only call Win32 ::SetCursor(nullptr) when io.MouseDrawCursor is set.

-// dear imgui: Platform Backend for Windows (standard windows API for 32-bits AND 64-bits applications)
-// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
-
-// Implemented features:
-//  [X] Platform: Clipboard support (for Win32 this is actually part of core dear imgui)
-//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy VK_* values are obsolete since 1.87 and not supported since 1.91.5]
-//  [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.

-// stb_rect_pack.h - v1.01 - public domain - rectangle packing
-// Sean Barrett 2014

-// Before #including,
-//
-//    #define STB_RECT_PACK_IMPLEMENTATION
-//
-// in the file that you want to have the implementation.
-//
-// Not necessarily the awesomest packing method, but better than

-// this is meant to replace).
-//
-// Has only had a few tests run, may have issues.
-//
-// More docs to come.
-//
-// No memory allocations; uses qsort() and assert() from stdlib.
-// Can override those by defining STBRP_SORT and STBRP_ASSERT.
-//
-// This library currently uses the Skyline Bottom-Left algorithm.
-//
-// Please note: better rectangle packers are welcome! Please

-# bbport's changes to BBSC
-
-This folder holds [BBSC](https://github.com/Classmg22/BBSC) 0.0.1 by CLS_AMG (GPL-2.0-or-later),
-as published at commit 315f76c, with the changes below made for the Linux port of bbport. Changed
-lines in BBSC's own files are marked `bbport:` in comments.
-
-## 2026-10-15
-
-- **Linux build.** `CMakeLists.txt` builds `libbbsc.so`, which bb-probe loads into the game.
-  - New files `emulator/mod/linux/`:
-    - `bbsc_mod_linux.cpp`, which replaces `bbsc_mod.cpp`;
-    - `bbsc_hooks_linux.cpp`, which replaces the Windows hook code;
-    - `bbsc_win32.h`, the Win32 and Winsock names the mod uses.
-  - Linux branches (`#ifdef`) in `emulator/mod/bbsc_relay.cpp`, `bbsc_channel.cpp` and
-    `bbsc_http.cpp`.
-- **Logs and captures.** BBSC keeps 5 of each, and stops a capture at 64 MB.
-- **Data folder.** BBSC's files go in the game's user folder, not the working directory.
-- **Memory search on Linux.** `emulator/src/core/bbsc_memscan.cpp` reads the readable mappings
-  through `process_vm_readv`.
-- **F8 key.** The F8 unstuck key works on Linux through SDL (`emulator/src/core/bloodborne_re.cpp`).
-- **Saves.** `BBSC_SAVE_DIR` is set to bbport's save folder (`savedata/<user>/<title id>/SPRJ0005`).
-- **Translations.** BBSC's texts follow the game's language:
-  - `emulator/src/core/bbsc_i18n.{h,cpp}` and `bbsc_translations.inc`, generated from
-    `translations/*.json` by `translations/gen_translations.py`;
-  - in `emulator/src/core/bloodborne_re.cpp`, BBSC's texts are passed through them.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License

-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software

-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>

-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this

-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-

-# Bloodborne Seamless Co-op (BBSC)
-
-Play the whole of Bloodborne together. BBSC is a mod for the [shadPS4](https://github.com/shadps4-emu/shadPS4)
-emulator that keeps a co-op session alive through deaths, lamps, area changes, bosses and the Hunter's
-Dream - up to five hunters, each keeping their own character.
-
-**Downloads:** Nexus Mods (link coming with the release) · **Community:** [Discord](https://discord.gg/Df7BCmfWdt)
-
-> 0.0.1 is the first public test. Back up your saves before playing.
-
-## Features
-
-- One co-op session that lasts through deaths, lamps, area changes, bosses and the Hunter's Dream
-- Up to 5 hunters: the host and 4 guests
-- Guests follow the host between areas and lamps and respawn with the group
-- Everyone keeps their own levels, echoes and items
-- Shared progress (optional): the host's boss kills and shortcuts are added to the guest's world
-- Guests get boss rewards and enemy drops; items already picked up do not come back
-- Enemy scaling by the number of hunters
-- A co-op kit with no Insight cost: Hunt Bell, Kin Bell, Bloodlust Bell, Parting Blank, Duel Bell (PvP toggle)
-- Clear co-op messages in place of the vanilla "beckoner / resonance" lines
-- Public server, self-hosted servers (Radmin VPN, Tailscale, LAN, VPS) and split screen (Nucleus Co-op)
-- Runs in shadPS4 and in the BBport Windows build
-
-## Requirements
-
-- Your own Bloodborne **CUSA03173, version 01.09** - no game files are included
-- Windows (the server also runs on Linux)
-
-## Downloads
-
-| File | For |
-|---|---|
-| `BBSC-<version>-Play.zip` | Players: launcher + emulator + BBSC, connects to the public server |
-| `BBSC-<version>-Server.zip` | Hosting your own server (Windows) |
-| `BBSC-<version>-Nucleus.zip` | Split screen with the [Bloodborne Nucleus Co-op Handler](https://github.com/framilano/BloodborneNucleusCoopHandler) |
-| `BBSC-<version>-BBport.zip` | Test build for the [BBport Windows build](https://github.com/Supermedo/bloodborne_pc) - same server as shadPS4 players |
-
-## Quick start
-
-1. Unzip the Play package and keep its files together.
-2. Run `PLAY BBSC.cmd`. Your shadPS4 settings, patches and saves are used as they are.
-3. Launcher > Settings > Accounts > Create Account on Server.
-4. Host rings the Hunt Bell, guests ring the Kin Bell.
-
-## Repository layout
-
-| Folder | Contents |
-|---|---|
-| `emulator/` | The shadPS4 fork (shadp2p based). BBSC game code: `src/core/bloodborne_re.cpp`; the mod DLL: `mod/` |
-| `launcher/` | The Qt launcher fork (Mods and Accounts tabs) |
-| `server/` | Host package scripts and the BBSC game server (`bbsc_gameserver.py`) |
-| `tools/` | Game data readers and helper tools |
-| `docs/` | Architecture, world sync, networking, known limitations, changelog |
-
-## Building
-
-- Emulator: `build/build-shadp2p.cmd` (Windows, Visual Studio 2022, CMake, Ninja)
-- Mod DLL: `emulator/mod/build-mod.cmd`
-- Game server: Python 3, no extra packages (`server/gameserver/bbsc_gameserver.py --shadnet <address>`)
-
-## Reporting bugs
-
-Post in `#bug-reports` on the [Discord](https://discord.gg/Df7BCmfWdt) with the version, host or guest,
-what happened and when, and both logs: the BBSC log (`mods/CUSA03173/bbsc/logs/`) and the emulator log
-(`user/log/shad_log.txt` or `%APPDATA%\shadPS4\log\`).

-// BBSC mod: the P2P channel - BBSC's own packets over the game's own player-to-player connection,
-// for servers that run no BBSC relay (the public ones: The Hunter's Dream + shadNet).
-//
-// The players of a session already exchange P2P datagrams (the game's socket, vport 40). The
-// emulator's P2P transport (official shadPS4: core/net/p2p_transport.cpp; the shadp2p fork:
-// network/p2p_sockets.cpp) carries a source and destination vport in every frame and hands each
-// frame to the socket bound to that vport, so a second socket on a vport of our own sees only
-// BBSC's frames and the game never sees them.
-//
-//   - Peers: the game's import slots for sceNetSendto/sceNetRecvfrom are wrapped; every address
-//     the game sends to or receives from on a P2P vport is a player of our session (kept while
-//     the game talks to it, dropped 20 s after). sceNpSignalingGetConnectionStatus is wrapped too
-//     (ACTIVE connections give the peer's address).
-//   - Socket: our own DGRAM_P2P socket on ChannelVport, made through the emulator's sceNet
-//     functions (the originals from the same slots), non-blocking, read by our own thread.
-//   - Frames: the relay's frames unchanged (the "SHAD" 0x40 envelope with sender + session,
-//     bbsc_relay.cpp), one datagram each; the receive side is the relay's Dispatch.
-//
-// Import slots, CUSA03173 01.09 (tools\eboot-imports.py, BBSC offsets):
-//   0x053E4B00 sceNetSocket   0x053E4B38 sceNetBind   0x053E4B68 sceNetSetsockopt
-//   0x053E4F48 sceNetSendto   0x053E4F58 sceNetRecvfrom
-//   0x053E52D0 sceNpSignalingGetConnectionStatus
-// Switch SHADPS4_BBSC_P2P_CHANNEL (Mods tab, on). Datagrams can be lost: every BBSC packet was
-// made for the emulator's UDP signaling first and is re-sent or repeated by its sender.

-// BBSC mod: the game's HTTP calls. In the emulator build, core/libraries/network/http.cpp
-// changes Bloodborne's summon traffic on its way out (Wozzardman's seamless route plus BBSC's
-// connect-first and stale-record cleanup). A mod cannot reach that code, so the DLL does it one
-// step earlier: it swaps the eboot's import slots (GOT entries the emulator filled at load) of
-// the libSceHttp functions the game calls for its own wrappers, which change the request and pass
-// it on to the emulator's function.
-//
-// Import slots, CUSA03173 01.09 (tools/gamedata/eboot_imports.py, BBSC offsets):
-//   0x053E5618 sceHttpCreateConnectionWithURL   0x053E5620 sceHttpCreateRequestWithURL

-//   0x053E5668 sceHttpReadData
-//
-// What the wrappers do:
-//   - URLs: the entries of host_overrides.json (same file and format as the emulator's) are
-//     applied here too, so a stock emulator reaches the BBSC game server and summon broker.
-//   - /summon_messenger/*: header X-ShadPS4-Bloodborne-Seamless: 1 (the broker's seamless mode).
-//   - summon search/request (a host looking for signs): the host's placement header, as the
-//     emulator sent it, AND the same text to every other player through the BBSC relay - the game
-//     does not import sceHttpGetAllResponseHeaders, so the guest cannot read it from the broker's
-//     reply; the relay brings it instead (bbsc_relay.cpp -> BbscMod::OnHostPlacement).
-//   - summon create (a guest's sign): the AreaId becomes the host's map once a host's placement
-//     is known (connect-first), and the first seamless create of this run sends a forced delete
-//     for the same SessionId/UserId first (stale broker record after a crash).
-//   - a claim the broker delivered with a sign that never became a join, and a session that
-//     ended, re-arm that delete: the next sign starts clean (see "Stuck claims" below).
-// Not done: the emulator's 3 s "fast sign" re-posts. They replaced the game's own reply; extra
-// posts from here would take the broker's claim themselves and the game would never join.

-// BBSC as a mod: a DLL that bbsc-launch.exe injects into shadPS4.exe before it starts.
-//
-// The DLL runs in the emulator's process, where the game's memory sits at its guest addresses
-// (eboot at 0x800000000 in the shadp2p fork; the official shadPS4 nightly of 2026-10-09 loads it
-// at 0x9B00000 - FindEbootBase looks for it), so it needs nothing from the emulator:
-//   1. wait until the eboot is in memory and every byte patch site reads back as the bytes that
-//      must be there (all of them before writing any - another game or version is left alone);
-//   2. write the byte patches (core/bbsc_patch_tables.h, the same list as the emulator build);
-//   3. install every hook with the emulator build's own code, core/bloodborne_re.cpp, compiled
-//      into this DLL with BBSC_MOD; its emulator calls are answered here and in bbsc_hooks.cpp
-//      (hook trampolines) and bbsc_relay.cpp (BBSC's packets, through the game server);
-//   4. keep watching: a patch site the emulator wrote back is written again.
-// Session suspensions and the lamp role toggles come from bloodborne_re.cpp as in the emulator
-// build (SetPersistentSessionPatches / SetHostLampPatches below).
-//
-// Log: logs\bbsc-mod-<date>-<time>-<pid>.log next to the DLL (one per game window, so two
-// windows on one PC do not overwrite each other); capture files in captures\ next to it.

-BBSC - HOST SERVER PACKAGE
-==========================
-Lets you host BBSC (Bloodborne Seamless Co-op) for your friends: the shadNet server (accounts,
-matchmaking, co-op summons) and the BBSC game server (messages, bloodstains, server list).
-Every player, you included, also needs the BBSC game package (BBSC-<build>.zip: launcher +
-emulator + BBSC mod) and their own copy of Bloodborne. No game files are included here.
-
-WHAT YOU NEED
-  - Windows 10/11
-  - One network you and your friends are all on: Radmin VPN, Hamachi, Tailscale, ZeroTier,
-    or the same house (same router / Wi-Fi).
-    Not a privacy VPN (ProtonVPN, NordVPN...) - friends cannot reach you through those.
-
-FIRST TIME (HOST)
-  1. Unzip this folder somewhere permanent (e.g. C:\BBSC-Host). Do not run it from inside the zip.
-  2. Double-click START-HOST.cmd
-     - if this PC is on more than one network it asks which one your friends use
-       (START-HOST-OTHER-NETWORK.cmd asks again later)
-     - say Yes to the Windows prompt (installs the C++ runtime, opens the firewall for VPN
-       addresses and your own local network only - nothing is opened to the internet;
-       older BBSC firewall rules that only allowed Radmin are updated)
-     - it creates your own empty account database and your own registration key
-     - it points YOUR game at your servers too
-  3. Double-click GENERATE-CARD.cmd. It asks a name, uses the same address as START-HOST
-     (Enter) and makes cards\BBSC-card-<name>.json with the address and your registration key.
-     Send that file to your friends in a DM - it holds your key, never post it publicly.
-  4. Your account: BBSC launcher > Settings > Accounts, pick your card, type a name and
-     password, Create Account on Server. (Or NEW-ACCOUNT.cmd, for yourself or a friend.)
-
-YOUR FRIENDS
-  1. Drag your card onto JOIN-HOST.cmd (in the BBSC game package). It connects their game to
-     your servers and adds the card to their launcher.
-     (No card? Double-click JOIN-HOST and paste the address START-HOST showed.)
-  2. BBSC launcher > Settings > Accounts > pick the card > name + password >
-     Create Account on Server. Accounts from other hosts do not exist on your server.
-
-EVERY TIME (HOST)
-  Double-click START-HOST.cmd and keep the two small server windows open while you play.
-  Changed network (e.g. Radmin to Hamachi)? START-HOST-OTHER-NETWORK.cmd, then GENERATE-CARD
-  again and send the new card.
-
-playit.gg
-  Account creation works through a playit tunnel, but co-op needs ports 31313-31315, 20443 and
-  20444 with the same numbers on one address, which playit's free tunnels do not give. Use
-  Radmin VPN, Hamachi or Tailscale for playing.
-
-KEEP PRIVATE
-  server\shadnet.cfg (your registration key), server\db\ (everyone's accounts),
-  server\host-address.txt and cards\ (your key again) are yours.
-  Never share them or zip them up for someone else - give out a fresh copy of this package.
-
-LOGS
-  server\logs\ - send these with a bug report.
-
-CREDITS
-  See CREDITS.txt. shadNet server: shadPS4 team / Wozzardman (shadnet-p2p). Server list format
-  and game server groundwork: Fahad (fhody125), No Dream For The Hunter.
-
-SOURCE CODE (GPL-2.0-or-later)
-  shadnet.exe and shadnet-sample.exe are built from https://github.com/Wozzardman/shadnet-p2p
-  (commit 5a849a1). The emulator BBSC runs on is built from https://github.com/Wozzardman/shadp2p
-  with the BBSC changes. Source for the BBSC changes is available from CLS_AMG on request.

-# BBSC game server
-
-What makes Bloodborne believe it is online, without depending on anybody else's machine.
-
-> Need help with any of this, or with shadPS4 and Bloodborne on PC generally?
-> Join the **Bloodborne PC** Discord — it is the main community for running this game on PC.
-
-## Why this exists
-
-Before Bloodborne enables a single online feature it fetches:
-
-```
-https://ss4.scej-network.jp:20443/bb-eu/ss.info
-```
-
-That file is **base64-encoded XML**, and it is the **server list**. A `<gameurl2>` block names one
-URL per game API — login, notices, blood messages, ghosts, summoning, play logs — plus the timing
-and matching parameters the online systems run on. Everything the game does afterwards goes
-wherever that file says.
-
-Private servers work by redirecting that one URL. Previously it pointed at `thehuntersdream.com`,
-so their `ss.info` decided where *our* co-op went. On 2026-09-21 their backend stopped responding
-(TCP connected, no HTTP reply, on both 18671 and 20443) and co-op stopped working for us with it.
-
-Serving our own removes that dependency for good.
-
-## What it does
-
-| Endpoints | Where they go |
-| --- | --- |
-| the four `api_SummonData*` | the real shadnet server — this is where co-op actually happens |
-| everything else | this process, which answers empty-but-valid JSON so the game stops asking |
-
-Blood messages, ghosts, notices and channels are **not implemented**. They get well-formed empty
-replies, which is enough to keep the game happy; this does not pretend to provide them.
-
-Each player runs their own copy on `127.0.0.1`. Only the summon endpoints are shared, which is why
-the shadnet address is the one thing you have to set.
-
-## Running it
-
-```
-python bbsc_gameserver.py --shadnet 100.101.102.103
-```
-
-Then in `%APPDATA%\shadPS4\host_overrides.json`:
-
-```json
-{ "https://ss4.scej-network.jp:20443": "http://127.0.0.1:20443" }
-```
-
-Standard library only — no Flask — so a stock Python runs it. Leave the window open while playing;
-it logs every request it answers, which is the fastest way to see whether the game is really
-talking to us.
-
-| Option | Effect |
-| --- | --- |
-| `--shadnet ADDR` | **required** — the machine running `shadnet.exe` |
-| `--summon-interval N` | seconds between summon-sign checks (retail 35 / 30) |
-| `--level-range N` | co-op level window (retail ±20) |
-| `--host` / `--port` | where to listen (default `127.0.0.1:20443`) |
-| `--advertise ADDR` | address to write into `ss.info` when it differs from `--host` |
-| `--verbose` | log request headers and bodies |
-
-Defaults change nothing except the addresses. Retuning is opt-in.
-
-## Retail tuning values
-
-Taken from the real `ss.info`, recorded here because they are not visible anywhere in the game and
-several of them explain behaviour we spent a long time blaming on the emulator.
-
-| Tag | Retail | What it controls |
-| --- | --- | --- |
-| `SummonDataGetListInterval2` | 35 | seconds between checks for a summon sign |
-| `SummonDataCreateInterval2` | 30 | how often a host re-posts its sign |
-| `SummonDataGetListGuardTimer2` | 60 | guard timer on the sign list |
-| `SummonDataGetListGetMaxCount2` | 20 | most signs returned at once |
-| `SummonDataCoopMatchingLevelUpperAbs2` | 20 | co-op level window, upper |
-| `SummonDataCoopMatchingLevelLowerAbs2` | −20 | co-op level window, lower |
-| `SummonDataBloodMadHunterPercent2` | 5 | blood-mad hunter chance |
-| `ReloadServerStatusInfoInterval2` | 300 | how often the game re-reads `ss.info` |
-
-**`SummonDataGetListInterval2` is what "quick summoning" means.** A sign can take over half a
-minute to appear on retail settings, and no amount of work inside the game could have changed it —
-the value lives in this file.
-
-## Credit
-
-The `ss.info` format, the endpoint list and the JSON response shapes come from
-[NoDreamForHunter](https://github.com/fhody125-web) by **fhody125**, MIT licensed — see
-`LICENSE.NoDreamForHunter`. He handed over the project and a real `ss.info` when thehuntersdream
-went down, which is the only reason any of this was possible. `ss_info_template.xml` is his file
-with the shadnet address left as a placeholder.
-
-This script is a standalone reimplementation rather than a fork: no Flask dependency, and it can
-retune the summon parameters on the way out.
