AppImage: only what the port needs, and DLSS's files intact

quick-sharun's OpenGL and Vulkan deployment copies every libEGL*/libGLX* library and every ICD
manifest of the build host. Built on a PC with NVIDIA's driver, the AppImage carried that
driver's user-space libraries (one exact version, 615.71.09 in 0.4-linux.1) and manifests,
which load next to the player's own driver and cannot match another kernel module. They are
now removed before the AppImage is made; NVIDIA's driver always comes from the host, where
launcher/bbport_vulkan.py points Vulkan.

quick-sharun also strips and patches every library in the AppDir, DLSS's among them. NVIDIA's
DLSS library is signed: changed, NGX refused it (0xbad00012) and DLSS was unavailable in the
AppImage on an RTX 3060 that runs it from the repository. The DLSS files are now copied after
quick-sharun, as built.

DEPLOY_PYTHON copied the build host's whole site-packages (scipy, Qt bindings, matplotlib, ...:
431 MB). Only PyGObject, pycairo and Pillow stay, which is all the launcher imports. The
AppImage goes from 342 MB to 225 MB.

+# bbport — a native Linux port of Bloodborne
+
+> This is the README of the original project (deadinside28/bloodborne_pc), kept for its
+> technical details. The fork's own README is [README.md](README.md).
+
+**English** · [Русский](BBPORT.ru.md)
+
+bbport is the counterpart of Wine + DXVK for a single game: *Bloodborne* for PlayStation 4
+(CUSA03173, game version 1.09) on an x86-64 Linux PC. The game's original executable runs
+directly on the PC:
+
+- **as in Wine**, the game's x86-64 code runs on the CPU directly, and a runtime written for
+  this one game replaces the PS4 system libraries;
+- **as in DXVK**, the game's graphics are translated to Vulkan — by a renderer derived from
+  [shadPS4](https://github.com/shadps4-emu/shadPS4) and heavily extended for this game, including
+  temporal upscaling with AMD FSR 3.1, FSR 4 and FSR 4.1.1;
+- memory and the GPU's work are moving to the PC model: the launcher has an experimental
+  *New memory and translation model* mode; without it the game runs on the old
+  memory model, as in 0.3.
+
+One step remains to the full Wine + DXVK model: make the new mode the default and remove the old
+memory model (see below).
+
+> **No game files are included.** You need your own dump of Bloodborne (CUSA03173, v1.09).
+> This project is not affiliated with Sony Interactive Entertainment, FromSoftware or AMD.
+
+**Status: experimental, playable.** The game boots, loads saves and plays (the Hunter's Dream
+and several areas of Yharnam were played with it) with sound, gamepad and saving.
+A full play-through has not been verified, and only one machine (Linux, AMD Radeon RX 7800 XT,
+Mesa/RADV) has been tested thoroughly.
+
+## Highlights
+
+- **Native execution.** The eboot is converted offline into a flat memory image; PS4 libc and
+  libSceFios2 are linked into it as native code. No CPU emulation and no per-instruction
+  translation: the game code runs at full speed.
+- **Two modes** (launcher → *Mode*):
+  - **Switch off (the default) — as in 0.3.** The old memory model: VRAM copies of the game's
+    memory, writes tracked through page protection. With every fix made since 0.3 (motion
+    vectors and the upscaler, flicker with DoF on, a damaged shader cache).
+  - **New memory and translation model — experimental.** The game's memory lives
+    in system RAM and the GPU reads it where it is, as a PC game's buffers; data it reads often
+    is kept in VRAM and given back when unused (textures after 20 s, buffers after 60 s). The
+    layer's memory module tracks CPU writes to mirrored blocks to keep those copies coherent;
+    it does not copy the whole GPU-visible memory. The PS4 command processor's work
+    is translated into Vulkan commands rather than emulated on the CPU: memory writes
+    (`WRITE_DATA`, DMA) are done by the GPU in command-stream order, and fences are written by the
+    GPU itself at the end of the pipeline, at the same point of the stream as the PS4's command
+    processor writes them. **It may crash**; hardware testing has been performed on an
+    RX 7800 XT, and performance depends on the scene and settings. On AMD the game's memory is kept
+    in a sparse buffer (the arena). **On NVIDIA, Intel and others** it goes through the layer's
+    memory module: the game's memory is bound in place and VRAM copies are separate buffers, with
+    no sparse rebinding. This avoids the sparse-binding path associated with reported freezes
+    on a GTX 1660 Ti. On NVIDIA the module runs on a tester's GTX 1660 Ti, its speed is still
+    being checked; not tested on Intel. Without the launcher: `BB_PC_MODEL=1`; to choose the memory
+    path: `BB_GUEST_MEMORY=host|dmabuf`; the memory module: `BB_LAYER_MEMORY=1/0`.
+
+  [0.5-pre4 changes](docs/CHANGES_0.5-pre4.md): no stutter of the memory module (NVIDIA) while areas
+  stream in, shader compilation in the background, VRAM on 4–6 GB cards, damaged game extractions
+  reported, the settings menu as in 0.3. [0.5-pre3](docs/CHANGES_0.5-pre3.md): the memory module on
+  NVIDIA — VRAM copies, one VRAM budget with the texture cache, watched blocks. [0.5-pre2](docs/CHANGES_0.5-pre2.md): the memory
+  module, native GPU copy shader, portable GPU completion labels, and shader-cache migration.
+
+  Unused textures are freed in both modes, so VRAM no longer grows with every area visited.
+- **Unlocked frame rate.** Community patches (`patches/Bloodborne.xml`) make the simulation
+  use the real frame time; ~90 FPS at 4K with FSR 4 Balanced on an RX 7800 XT, ~150 FPS at
+  1440p with FSR 4 Quality. Also 30/60/90 FPS modes.
+- **Temporal upscaling built for this game.** Bloodborne has no velocity buffer, so bbport
+  computes motion vectors itself: camera motion from depth and the scene matrices, and object
+  motion (characters, cloth, weapons) from the vertex positions of the previous frame. The
+  scene is jittered sub-pixel (Halton) and rendered at a reduced resolution; the upscaler fills
+  the output (720p for the Steam Deck, 1080p, 1440p or 2160p) and the UI is drawn natively at the output resolution.
+  - **FSR 3.1** (FireBurn/FSR-Vulkan).
+  - **FSR 4 (INT8, model v07)** on GPUs exposing the required Vulkan shader features —
+    RDNA2/3 included (see Requirements).
+  - **FSR 4.1.1**: AMD's 4.1.1 DLL is recorded once under vkd3d-proton and its passes are
+    replayed natively on Vulkan; the output is **bit-exact** with the DLL. Two variants, as in
+    the DLL: INT8 on any GPU with the required shader features, and FP8 matrices on RDNA4 (RX
+    9000; picked automatically). The assets are built on your machine from one DLL of your own
+    (4.1.x): the launcher's *FSR 4.1.1 from your own AMD DLL → Choose DLL…* button (2–5 minutes,
+    twice that on RDNA4; needs a recent Proton), or `tools/fsr4cap`.
+  - Faster than AMD's own shaders on RDNA3: the final passes of FSR 4 and 4.1.1 were rewritten
+    to store through workgroup memory (3.5× and 2.3× faster, bit-exact); FSR 4 costs ~4 ms at
+    4K on an RX 7800 XT instead of ~6 ms.
+- **Multi-threaded GPU command processing.** The PS4 command stream is decoded on one thread
+  and draws are bound and recorded on another (two-stage pipeline), with a Vulkan recording
+  thread and helper threads for memory copies. Early on the single GPU thread capped the game
+  at ~26 FPS; now it runs at 90–150 FPS depending on resolution and scene.
+- **Settings inside the game's own menu:** *System → Display / Game effects / Game patches*
+  (after *Screen/Sound*), built and drawn by the game itself — output resolution, upscaler,
+  preset, sharpness, FPS counter, model detail and the effect patches, in the game's language.
+- **Overlay menu** (Insert or L3+R3), styled like the game's dialogs: everything above plus the
+  advanced settings, with gamepad, keyboard and mouse.
+- **GTK4 launcher** and an **AppImage** for the Steam Deck.
+
+## How it differs from shadPS4
+
+| | shadPS4 | bbport |
+|---|---|---|
+| Scope | General PS4 emulator, many games | One game: Bloodborne v1.09 |
+| Loading | Its own ELF loader and kernel emulation at run time | The eboot is converted offline (`scripts/`) into an image with PS4 libc/Fios2 linked in; a C loader maps it and jumps into the game (loader and runtime: ~5k lines) |
+| Memory | The GPU's view of PS4 memory is kept in VRAM copies, synchronized through page-protection write tracking | By default the same model (as in 0.3); in the *New memory and translation model* mode: the game's memory in system RAM, used by the GPU in place, frequently read data in VRAM, freed when unused |
+| Command processor | Emulated: memory writes, DMA and fences are done by the CPU while decoding | By default the same; in the new mode translated into Vulkan commands that the GPU runs in stream order, fences written after the work has really finished |
+| System libraries | Broad HLE of the PS4 OS | A small runtime (`src/runtime_*.c`) that implements exactly what Bloodborne calls: memory, threads, sync, files, audio (incl. ATRAC9), pad, saves, AppContent |
+| GPU | shadPS4 video core and shader recompiler | The same core (vendored, GPL) with ~200 marked changes (`bbport:`) plus new modules: two-stage draw pipeline, render-state and texture-set memoization, render-scale proxies, motion vectors, FSR 3.1/4/4.1.1, frame capture and GPU profiler |
+| GPU thread | One thread processes the whole command stream (the bottleneck in Bloodborne) | Decode and draw recording run on separate threads; the work scales with the hardware threads (Steam Deck included) |
+| Upscaling | — | Temporal (FSR 3.1, FSR 4, FSR 4.1.1) with the game's own motion vectors and jitter |
+| Game patches | Patch files applied by the emulator | The same community patches, compiled at start (`scripts/patches.py`); render resolution, effects and FPS from the launcher |
+
+Without shadPS4 there would be no bbport: its renderer and shader recompiler are the base of
+the graphics side.
+
+### Wine + DXVK for one game
+
+- **CPU.** The PS4 CPU is x86-64, so the game's code runs directly on the PC's CPU, with no
+  emulation and no instruction translation.
+- **System libraries.** As Wine replaces the Windows API, the bbport runtime (`src/runtime_*.c`)
+  implements exactly the PS4 OS functions Bloodborne calls: memory, threads, files, audio, pad,
+  saves.
+- **Memory.** In the new mode, as in a PC game: the game's data in system RAM, VRAM used the way
+  a PC game uses it. The mode is still experimental.
+- **Graphics.** The PS4 GPU's command stream (PM4) is a recording of the game's graphics API
+  calls: it is written by 99 functions of the statically linked libGnm, so decoding the stream
+  and translating the calls themselves come to the same thing. GCN shaders are translated to
+  SPIR-V. In the new mode the command processor's work (memory writes, DMA, fences) is
+  translated into Vulkan commands as well; fences are written by the GPU itself. Resource
+  descriptors (textures, buffers) are read by the translator on the CPU, as DXVK reads resource
+  bindings: a PS4 texture has to be converted from the PS4 tiling into a Vulkan image before the
+  draw runs, so the CPU must know its descriptor beforehand — translation, not emulation. The
+  descriptor tables (the constant engine's dumps) are read only by the translator, so the CPU
+  performs them. The game's occlusion queries (~60 a frame) are
+  Vulkan occlusion queries; predication, `COPY_DATA` and `COND_EXEC` are translated too (check:
+  `BB_PM4_SELFTEST=1`). Details:
+  [docs/EMULATION_REMOVAL_PLAN.ru.md](docs/EMULATION_REMOVAL_PLAN.ru.md), "Шаг 4" (Russian).
+
+"Port" here means a build for this one game, not a rewrite of its source code, which the project
+neither has nor includes.
+
+## Requirements
+
+- Linux x86-64, a Vulkan 1.3 GPU. Tested: AMD RX 7800 XT with Mesa 26 (RADV).
+  The *New memory and translation model* mode is not tested on NVIDIA yet.
+  FSR 4 / 4.1.1 require shader Float16, Int8/Int16, integer dot products, linear compute
+  derivatives and extended storage image formats; FSR 4.1.1 additionally requires
+  `VK_VALVE_shader_mixed_float_dot_product`. Unsupported choices fall back to FSR 3.1
+  before the first frame and are disabled in the in-game menu.
+- Your decrypted game dump: the `CUSA03173` folder (eboot.bin, sce_module, ...), version 1.09.
+  The US release (`CUSA00900`) runs too: its 1.09 executable is the same as this European
+  Game of the Year edition's.
+  A dumped update is a separate folder: copy it over the base game, replacing files. The base
+  game alone (1.00) crashes at start (guest offset 0x20348b8); the launcher and `run.sh` check
+  the executable and say what is missing (`BB_SKIP_GAME_CHECK=1` skips the check). Some dumps
+  ship the 1.09 eboot.bin with Lance McDonald's 60 fps patch baked in; that one crashes when the
+  gestures menu opens, and the check asks for a clean eboot.bin (bbport has its own 60 fps).
+- To build: GCC, CMake, Ninja, Python 3, glslang, SDL3, Vulkan headers and the libraries in
+  `shell.nix`. With [Nix](https://nixos.org) everything comes from `shell.nix` automatically.
+
+## Build and run
+
+```bash
+git clone --recursive https://github.com/deadinside28/bloodborne_pc.git bbport && cd bbport
+bash build.sh                        # builds out/bb-probe and out/gpu/libbbgpu.so
+BB_GAME_DIR=/path/to/CUSA03173 bash run.sh
+```
+
+or the launcher (pick the game folder, settings, *Start*):
+
+```bash
+bash launcher/bb-launcher.sh         # launcher/install-desktop.sh adds it to the app menu
+```
+
+By default the game folder is expected next to the repository (`../CUSA03173`). Saves and the
+shader cache go to `user/` (the launcher lets you choose another folder); settings to
+`bbport.ini`. A gamepad is used through SDL3 (the launcher's *Controls → Controller* picks one
+when several are connected; `BB_GAMEPAD=<GUID or part of the name>`). The keyboard works too,
+also next to a connected gamepad (the Steam Deck always has one); both are remapped in the
+launcher (*Controls*). The character name is typed on the keyboard in a box over the game.
+The touchpad: its left half (Tab, Back/Select) opens the gestures, the right half (Backspace)
+the key items. There is no PSN: the *Play online / offline* screen is skipped and the game opens
+its main menu offline (a game patch; the launcher's *Game effects → Skip the “play online / offline” choice*,
+`BB_SKIP_NETWORK_CHOICE=0` shows it). With several monitors, *Screen → Monitor* in the launcher
+(`BB_DISPLAY=<number or part of the name>`) picks the one for the game.
+
+Add-ons: `BB_DLC_DIR=/path/to/dlc` (the launcher's *DLC folder*) holds the dumped add-ons of
+the game, one folder each named by its entitlement label (`SPEXPANSIONDLC03/sce_sys/...`).
+Their data ships with the 1.09 update, so a folder with only `sce_sys` is enough. `run.sh` links
+it as `user/addcont/<title id>`, where the runtime finds add-ons (see **DLC** below); a real
+folder already there is kept. The GOTY edition (CUSA03173) needs none.
+
+**Resolution and preset changes:** for outputs other than 1080p (720p on the Steam Deck,
+1440p, 4K) the whole game renders at the preset's resolution, set by a patch at start — the
+fastest path. Changing the output or the preset in the in-game menu then needs *Apply and
+restart the game*. The *Live resolution changes* setting (launcher, in-game menu,
+`bbport.ini` `live_resolution=0|1|auto`; **off by default**) instead keeps the game at
+1080p internally and scales its render targets at run time, so 720p/1080p/1440p/4K and the
+presets switch without a restart. It costs more: the game then believes it renders 1080p
+and draws more (e.g. ~8× more small lights), and some targets are copied between sizes —
+use it on strong desktop GPUs only (`auto` turns it on for discrete GPUs with 8+ GB that are
+not pre-Turing NVIDIA). 1080p output and TAA always use the live path.
+
+**TAA:** a separate native-resolution temporal AA mode in the launcher and overlay,
+switchable live without an FSR model. The saved FSR preset is restored when returning
+to FSR. FSR Native AA adds reconstruction on top of full-resolution rendering and can
+be slower than disabling AA. TAA also adds work compared with no temporal AA.
+The RCAS switch and the 0–2 sharpness control also work with TAA. Sharpening runs after
+temporal accumulation and leaves its history and HUD unchanged.
+
+**Mods:** the launcher accepts separate loose-file mod folders (with `dvdroot_ps4/`, an extra
+wrapper folder, or the game folders such as `chr/` directly; file name case does not matter),
+with enable switches and load order. A sibling `CUSA03173-mods/` overlay also works.
+The original game is preserved; later mods override conflicting files.
+**Third-party patches:** shadPS4-format XML patch files in the data directory's `patches/`,
+switched on and off in the launcher. See [mods and patches](docs/MODS.md).
+**DLC:** put your add-on dumps in `user/addcont/<title id>/<entitlement label>/` (shadPS4's
+layout, e.g. `user/addcont/CUSA03173/SPEXPANSIONDLC03` for The Old Hunters): each folder there is
+reported to the game as an installed add-on.
+
+**Launcher language:** Russian, English, Brazilian Portuguese, Spanish, Italian, French, German or Simplified Chinese (follows the system language by default).
+**Game language:** the PS4 system language, *System language* in the launcher; by default it
+follows the desktop's locale (Japanese, English, French, Spanish, German, Italian or Russian,
+English for the rest). `run.sh` takes it as `BB_LANGUAGE` (PS4 code: 0 Japanese, 1 English,
+2 French, 3 Spanish, 4 German, 5 Italian, 8 Russian; without it, the desktop's locale as above).
+**Game region:** *Game region* in the launcher, `BB_REGION=eu|na` for `run.sh`: the regional text
+of a language, such as Spanish from Spain (`eu`) or Latin American Spanish (`na`). It sets the
+game's `USER_DEFINED_PARAM_1` (13 Europe, 2 the Americas) for the launch; by default the dump's
+`param.sfo` decides.
+
+**Free camera and game debug menu** (v1.09): enable the corresponding switches in the
+launcher or in-game menu and restart. Free camera uses Lance McDonald's
+[GoldHEN patch](https://github.com/GoldHEN/GoldHEN_Patch_Repository/blob/main/patches/xml/Bloodborne-Orbis.xml):
+hold Cross and press L3 to cycle modes (keyboard: hold Space and press Z). It needs no fonts
+and conflicts with *Enemy Control*.
+For the game debug menu, install `DbgFont14h.ccm` and `DbgFont14h.tpf` from
+[Debug Menu and XML Patch](https://www.nexusmods.com/bloodborne/mods/253) into the game's
+`dvdroot_ps4/font/` first. Startup rejects missing or empty font files instead of launching
+the unsafe patch. Open it with the left touchpad / Tab (with the debug menu on, the left half
+no longer opens the gestures); Backspace is the right touchpad.
+Touch coordinates are forwarded from SDL gamepads; Back/Select emulates a left click on
+pads without a touch surface. The port's settings menu remains Insert / L3+R3.
+
+GPU occlusion queries still use synthetic pixel counters (`PixelPipeStatDump`), and
+`IT_SET_PREDICATION` is unimplemented. Free camera allows visual investigation; it does
+not implement GPU occlusion culling.
+
+**Upscaler assets** (not included; FSR 3.1 needs none):
+
+```bash
+bash tools/fetch_fsr4_assets.sh      # FSR 4 v07 (MIT, built from AMD's source by Q2RTX)
+# FSR 4.1.1, from your own AMD DLLs (e.g. OptiScaler's FSR4_LATEST), needs GE-Proton 10 or newer:
+bash tools/fsr4cap/build_assets.sh <amd_fidelityfx_upscaler_dx12.dll>
+```
+
+**FSR 4.1.1 from your own DLL.** The easiest way is the launcher: *Upscaler → FSR 4.1.1 from your
+own AMD DLL → Choose DLL…*, then pick `amd_fidelityfx_upscaler_dx12.dll` version 4.1.x: from
+OptiScaler's `FSR4_LATEST` folder or from a game with FSR 4.1. That one file is enough: AMD's DLL
+exports the FidelityFX API itself, so no loader is needed (only a DLL without these exports would
+be recorded through `amd_fidelityfx_loader_dx12.dll`, and the launcher would ask for it). The DLL is checked at once,
+without a long capture; these do not fit: AMD's official FSR 4.0.x (e.g. Pragmata's 4.0.3 —
+AMD enables it on RDNA4 only, and under Proton it does not start on other GPUs) and community
+builds (4.0.2b, 4.1.1b and similar OptiScaler INT8 builds: another model and pass count). Then
+the DLL runs under Proton and is recorded at 20 sizes (progress in the row and in the *Log* tab;
+on RDNA4 a second time, for the FP8 variant),
+the passes are translated to SPIR-V, and FSR 4.1.1 is selected. The Proton build is picked
+automatically — the first under which the DLL enables FSR 4.1: GE-Proton 10 or newer,
+Proton-CachyOS, Proton Experimental (tested: GE-Proton 11, Proton-CachyOS 11, Experimental of
+October 2026; Steam's Proton 11.0 and GE-Proton 9 do not). It runs in the Steam runtime it
+requires (Steam installs it the first time any game runs with that Proton), or through
+umu-launcher when installed. On NixOS umu-launcher comes from `nix-shell` (downloaded the first
+time, ~1.7 GB); the AppImage runs the recording on the system itself, through the user's systemd
+(`systemd-run --user`), since the system's `/nix` is out of its sight. Recording on the Steam Deck is not verified yet; if the DLL does not
+enable FSR 4.1 there, build on a PC and copy the `fsr4_411` folder. The same from the command
+line: the launcher's (and the AppImage's) `--build-fsr411 <DLL>`.
+
+**DLSS (NVIDIA GeForce RTX).** NVIDIA's DLSS SDK is not included: check out
+[github.com/NVIDIA/DLSS](https://github.com/NVIDIA/DLSS) (`include/` and `lib/Linux_x86_64` are
+enough) and build with `DLSS_SDK_ROOT=/path/to/DLSS bash build.sh`. That also builds the bridge
+`out/libbbport_dlss.so` (`gpu/dlss_bridge`, the only code that uses the SDK) and copies NVIDIA's
+`libnvidia-ngx-dlss.so.<version>` next to `out/bb-probe`; the driver provides the rest. Then pick
+*DLSS* in the launcher or the in-game menu: the preset sets the render size, Native AA is DLAA.
+DLSS gets the inputs FSR 3.1 gets (scene color, depth, motion vectors, jitter). Without the
+libraries, on other GPUs or with `BB_DLSS=0` it is listed as unavailable, and a DLSS setting falls
+back to FSR 3.1.
+
+From source the script takes its tools from the system (MinGW GCC, CMake, Ninja, Python 3,
+SPIRV-Tools, Git) or from Nix; the AppImage has them prebuilt.
+
+**FP8 on RDNA4.** When vkd3d-proton offers FP8 cooperative matrices (RDNA4), the DLL runs
+another variant of its passes: other shaders and weights, other dispatch sizes. The build records
+both, INT8 into `fsr4_411/` and FP8 into `fsr4_411/fp8/`, and the game picks FP8 itself when the
+GPU has FP8 matrices (`VK_EXT_shader_float8`); the log says `Upscaler: FSR 4.1.1 replay, FP8 …`.
+`BB_FSR411_VARIANT=int8` forces INT8. Checked on an RX 7800 XT through vkd3d-proton's FP16
+emulation of FP8 (`BB_FSR4CAP_FP8=1` records it there too, `fp8emu/`): bit-exact with the DLL;
+**not yet run on RDNA4 hardware.**
+
+**AppImage** (Steam Deck): `bash build.sh && bash packaging/appimage.sh` →
+`dist/Bloodborne-bbport-x86_64.AppImage`; data in `~/.local/share/bbport`, `--play` starts the
+game without the launcher window (Game Mode). FSR 4.1.1 models are not packaged: build them with
+the launcher's button (see above); they go to `~/.local/share/bbport/fsr4_411`
+(`BB_PACKAGE_FSR411=1` bundles a local `fsr4_411` into an AppImage for your own devices). On the Steam Deck pick the 1280×720 output (the
+game is 16:9; on the 1280×800 screen it gets thin bars).
+
+**Adding the AppImage to Steam** (*Add a Non-Steam Game*) needs no options; the compatibility tool
+does not matter. (Steam preloads its overlay into every non-Steam game; the AppImage removes it
+before its own programs start, so the Steam overlay is not shown in the game.) Where Steam
+runs games without FUSE (NixOS: Steam's FHS sandbox; the AppImage then exits with *Cannot mount
+AppImage*), set the launch options to
+
+```
+TMPDIR=$HOME/.cache APPIMAGE_EXTRACT_AND_RUN=1 NO_CLEANUP=1 %command%
+```
+
+The AppImage then unpacks itself (~2 GB, `~/.cache/appimage_extracted_*`) on the first start
+(~10 s) and reuses that copy afterwards; a new AppImage version gets a new copy, the old one can
+be deleted. Without `TMPDIR` it would unpack into Steam's `/tmp`, which is in RAM there. Add
+` --play` after `%command%` to skip the launcher.
+
+**NVIDIA in the AppImage:** startup discovers the host's installed 64-bit NVIDIA Vulkan ICD
+and exposes its vendor libraries alongside the bundled AMD/Intel drivers. This keeps the
+NVIDIA userspace driver matched to the host kernel module. Standard Linux distributions keep
+these libraries under `/usr/lib*`; on NixOS the AppImage's internal `/nix/store` may hide them.
+In that case copy the NVIDIA libraries into an accessible directory and set
+`BB_NVIDIA_LIB_DIR=/path/to/libraries` (the NVIDIA manifest must also be accessible).
+Explicit `VK_DRIVER_FILES`/`VK_ICD_FILENAMES` overrides are preserved. Diagnose drivers inside
+the package with:
+
+```bash
+./Bloodborne-bbport-x86_64.AppImage --vulkan-info 2>&1 | tee bbport-vulkan.log
+```
+
+A user reported successful startup with FSR 3 on a GTX 1060 6GB (Fedora 44, NVIDIA
+580.178.04); selecting FSR 4 caused a black window. Use FSR 3 on this configuration.
+
+MangoHud is bundled in the AppImage; enable its checkbox in the launcher. If MangoHud is also
+installed system-wide, or Steam's performance overlay is on (Steam Deck game mode), only one
+overlay is drawn (two drew doubled, offset text).
+When running from source, install MangoHud separately. A diagnostic launch with
+`VK_LOADER_LAYERS_DISABLE=~implicit~` also disables MangoHud.
+
+Useful variables: `BB_FRAME_STATS=1` (frame statistics, including a `Memory:` line: VRAM, GTT,
+RSS, images and guest blocks in VRAM), `BB_PC_MODEL=1` (the new memory and translation model,
+0, the old model as in 0.3, is the default), `BB_ANISO=N` (anisotropic filtering of scene textures; 16 by
+default, 0 = the game's own),
+`BB_GC_IDLE_SECONDS=N` / `BB_VRAM_IDLE_SECONDS=N` (how long unused textures / buffers stay in VRAM;
+20 / 60), `BB_BREADCRUMBS=0` (no GPU breadcrumbs; with them a GPU hang names the draw or dispatch
+it is stuck in), `BB_GPU_PROFILE=1` (GPU time per
+pass), `BB_FSR4_PROFILE=1` (GPU time per FSR 4 pass), `BB_UPSCALER=taa|fsr3|fsr4|fsr411|off|none`,
+`BB_FRAMES_AHEAD=N` (how many frames the GPU command thread may run ahead of the GPU; 1 by default,
+0 = unbounded), `BB_PRESENT_THREAD=0` (present on the vblank thread, as before),
+`BB_LIVE_RES=1` (live resolution changes instead of the startup patch for outputs other than 1080p),
+`BB_PAD_RECORD=file` / `BB_PAD_REPLAY=file` (record a route with F9, replay it in scripted tests),
+`BB_GC_BUDGET_MB=N` (texture cache budget, as on integrated GPUs), `BB_VRAM_LIMIT_MB=N` (the VRAM
+budget taken as at most N MiB: checks the behaviour of cards with little VRAM), `BB_ASYNC_PIPELINES=0`
+(new pipelines compile at once and the game waits; by default in the background), `BB_PRESENT_DUMP_TRIGGER=file`
+with `BB_PRESENT_DUMP_COUNT=N` (dump N consecutive presented frames),
+`BB_FSR411_VARIANT=int8|fp8|fp8emu` (FSR 4.1.1 variant; by default FP8 where the GPU has FP8
+matrices), `BB_READBACKS=0|1|2` (reads of GPU-written memory by the game: 1 by default, 2
+precise and slow, 0 off).

+## 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.
+- 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.
+- 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.
+- 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.

-bbport is the counterpart of Wine + DXVK for a single game: *Bloodborne* for PlayStation 4
-(CUSA03173, game version 1.09) on an x86-64 Linux PC. The game's original executable runs
-directly on the PC:
+## Features
 
-- **as in Wine**, the game's x86-64 code runs on the CPU directly, and a runtime written for
-  this one game replaces the PS4 system libraries;
-- **as in DXVK**, the game's graphics are translated to Vulkan — by a renderer derived from
-  [shadPS4](https://github.com/shadps4-emu/shadPS4) and heavily extended for this game, including
-  temporal upscaling with AMD FSR 3.1, FSR 4 and FSR 4.1.1;
-- memory and the GPU's work follow the PC model on AMD GPUs by default (the new memory and
-  translation model); NVIDIA and other GPUs keep the old memory model of 0.3 for now. The
-  launcher's *Memory model* switches either way.
-
-One step remains to the full Wine + DXVK model: the new model on NVIDIA as well, then removing the
-old memory model (see below).
-
-> **No game files are included.** You need your own dump of Bloodborne (CUSA03173, v1.09).
-> This project is not affiliated with Sony Interactive Entertainment, FromSoftware or AMD.
-
-**Status: experimental, playable.** The game boots, loads saves and plays (the Hunter's Dream
-and several areas of Yharnam were played with it) with sound, gamepad and saving.
-A full play-through has not been verified, and only one machine (Linux, AMD Radeon RX 7800 XT,
-Mesa/RADV) has been tested thoroughly.
-
-## Highlights
-
-- **Native execution.** The eboot is converted offline into a flat memory image; PS4 libc and
-  libSceFios2 are linked into it as native code. No CPU emulation and no per-instruction
-  translation: the game code runs at full speed.
-- **Two memory models** (launcher → *Mode → Memory and translation model*; *Auto*, the default,
-  picks by GPU):
-  - **The old memory model, as in 0.3 — the default on NVIDIA, Intel and others.** VRAM copies
-    of the game's memory, writes tracked through page protection. With every fix made since 0.3
-    (motion vectors and the upscaler, flicker with DoF on, a damaged shader cache).
-  - **The new memory and translation model — the default on AMD.** The game's memory lives
-    in system RAM and the GPU reads it where it is, as a PC game's buffers; data it reads often
-    is kept in VRAM and given back when unused (textures after 20 s, buffers after 60 s). The
-    layer's memory module tracks CPU writes to mirrored blocks to keep those copies coherent;
-    it does not copy the whole GPU-visible memory. The PS4 command processor's work
-    is translated into Vulkan commands rather than emulated on the CPU: memory writes
-    (`WRITE_DATA`, DMA) are done by the GPU in command-stream order, and fences are written by the
-    GPU itself at the end of the pipeline, at the same point of the stream as the PS4's command
-    processor writes them. On AMD the game's memory is kept in a sparse buffer (the arena); on
-    NVIDIA, Intel and others it goes through the layer's memory module: bound in place, VRAM
-    copies as separate buffers, no sparse rebinding (NVIDIA's sparse binding froze the GPU for
-    seconds); `BB_LAYER_MEMORY=1/0` chooses by hand. Tested on an RX 7800 XT. On NVIDIA it can be chosen by hand (*New*); testers' results differ by scene,
-    some scenes are slower than with the old model, so it is not the default there yet. Not
-    tested on Intel. Without the launcher: `BB_PC_MODEL=1/0` (unset: by GPU, as *Auto*).
-
-  [Changes in 0.5](docs/CHANGES_0.5.md); the prereleases: [pre4](docs/CHANGES_0.5-pre4.md),
-  [pre3](docs/CHANGES_0.5-pre3.md), [pre2](docs/CHANGES_0.5-pre2.md).
-
-  Unused textures are freed in both modes, so VRAM no longer grows with every area visited.
-- **Unlocked frame rate.** Community patches (`patches/Bloodborne.xml`) make the simulation
-  use the real frame time; ~90 FPS at 4K with FSR 4 Balanced on an RX 7800 XT, ~150 FPS at
-  1440p with FSR 4 Quality. Also 30/60/90 FPS modes.
-- **Temporal upscaling built for this game.** Bloodborne has no velocity buffer, so bbport
-  computes motion vectors itself: camera motion from depth and the scene matrices, and object
-  motion (characters, cloth, weapons) from the vertex positions of the previous frame. The
-  scene is jittered sub-pixel (Halton) and rendered at a reduced resolution; the upscaler fills
-  the output (720p for the Steam Deck, 1080p, 1440p or 2160p) and the UI is drawn natively at the output resolution.
-  - **FSR 3.1** (FireBurn/FSR-Vulkan).
-  - **FSR 4 (INT8, model v07)** on GPUs exposing the required Vulkan shader features —
-    RDNA2/3 included (see Requirements).
-  - **FSR 4.1.1**: AMD's 4.1.1 DLL is recorded once under vkd3d-proton and its passes are
-    replayed natively on Vulkan; the output is **bit-exact** with the DLL. Two variants, as in
-    the DLL: INT8 on any GPU with the required shader features, and FP8 matrices on RDNA4 (RX
-    9000; picked automatically). The assets are built on your machine from one DLL of your own
-    (4.1.x): the launcher's *FSR 4.1.1 from your own AMD DLL → Choose DLL…* button (2–5 minutes,
-    twice that on RDNA4; needs a recent Proton), or `tools/fsr4cap`.
-  - Faster than AMD's own shaders on RDNA3: the final passes of FSR 4 and 4.1.1 were rewritten
-    to store through workgroup memory (3.5× and 2.3× faster, bit-exact); FSR 4 costs ~4 ms at
-    4K on an RX 7800 XT instead of ~6 ms.
-- **Multi-threaded GPU command processing.** The PS4 command stream is decoded on one thread
-  and draws are bound and recorded on another (two-stage pipeline), with a Vulkan recording
-  thread and helper threads for memory copies. Early on the single GPU thread capped the game
-  at ~26 FPS; now it runs at 90–150 FPS depending on resolution and scene.
-- **Settings inside the game's own menu:** *System → Display / Effects* (after *Screen/Sound*),
-  built and drawn by the game itself — output resolution, upscaler, preset, sharpness, FPS
-  counter, model detail and the game's effects, in the game's language.
-- **Overlay menu** (Insert or L3+R3), styled like the game's dialogs: everything above plus the
-  advanced settings, with gamepad, keyboard and mouse.
-- **GTK4 launcher** and an **AppImage** for the Steam Deck.

-## How it differs from shadPS4
-
-| | shadPS4 | bbport |
-|---|---|---|
-| Scope | General PS4 emulator, many games | One game: Bloodborne v1.09 |
-| Loading | Its own ELF loader and kernel emulation at run time | The eboot is converted offline (`scripts/`) into an image with PS4 libc/Fios2 linked in; a C loader maps it and jumps into the game (loader and runtime: ~5k lines) |
-| Memory | The GPU's view of PS4 memory is kept in VRAM copies, synchronized through page-protection write tracking | By default the same model (as in 0.3); in the *New memory and translation model* mode: the game's memory in system RAM, used by the GPU in place, frequently read data in VRAM, freed when unused |
-| Command processor | Emulated: memory writes, DMA and fences are done by the CPU while decoding | By default the same; in the new mode translated into Vulkan commands that the GPU runs in stream order, fences written after the work has really finished |
-| System libraries | Broad HLE of the PS4 OS | A small runtime (`src/runtime_*.c`) that implements exactly what Bloodborne calls: memory, threads, sync, files, audio (incl. ATRAC9), pad, saves, AppContent |
-| GPU | shadPS4 video core and shader recompiler | The same core (vendored, GPL) with ~200 marked changes (`bbport:`) plus new modules: two-stage draw pipeline, render-state and texture-set memoization, render-scale proxies, motion vectors, FSR 3.1/4/4.1.1, frame capture and GPU profiler |
-| GPU thread | One thread processes the whole command stream (the bottleneck in Bloodborne) | Decode and draw recording run on separate threads; the work scales with the hardware threads (Steam Deck included) |
-| Upscaling | — | Temporal (FSR 3.1, FSR 4, FSR 4.1.1) with the game's own motion vectors and jitter |
-| Game patches | Patch files applied by the emulator | The same community patches, compiled at start (`scripts/patches.py`); render resolution, effects and FPS from the launcher |
-
-Without shadPS4 there would be no bbport: its renderer and shader recompiler are the base of
-the graphics side.
-
-### Wine + DXVK for one game
-
-- **CPU.** The PS4 CPU is x86-64, so the game's code runs directly on the PC's CPU, with no
-  emulation and no instruction translation.
-- **System libraries.** As Wine replaces the Windows API, the bbport runtime (`src/runtime_*.c`)
-  implements exactly the PS4 OS functions Bloodborne calls: memory, threads, files, audio, pad,
-  saves.
-- **Memory.** In the new mode, as in a PC game: the game's data in system RAM, VRAM used the way
-  a PC game uses it. The mode is still experimental.
-- **Graphics.** The PS4 GPU's command stream (PM4) is a recording of the game's graphics API
-  calls: it is written by 99 functions of the statically linked libGnm, so decoding the stream
-  and translating the calls themselves come to the same thing. GCN shaders are translated to
-  SPIR-V. In the new mode the command processor's work (memory writes, DMA, fences) is
-  translated into Vulkan commands as well; fences are written by the GPU itself. Resource
-  descriptors (textures, buffers) are read by the translator on the CPU, as DXVK reads resource
-  bindings: a PS4 texture has to be converted from the PS4 tiling into a Vulkan image before the
-  draw runs, so the CPU must know its descriptor beforehand — translation, not emulation. The
-  descriptor tables (the constant engine's dumps) are read only by the translator, so the CPU
-  performs them. The game's occlusion queries (~60 a frame) are
-  Vulkan occlusion queries; predication, `COPY_DATA` and `COND_EXEC` are translated too (check:
-  `BB_PM4_SELFTEST=1`). Details:
-  [docs/EMULATION_REMOVAL_PLAN.ru.md](docs/EMULATION_REMOVAL_PLAN.ru.md), "Шаг 4" (Russian).
-
-"Port" here means a build for this one game, not a rewrite of its source code, which the project
-neither has nor includes.
+- **Online play (beta)** through [The Hunter's Dream](https://thehuntersdream.com) and shadNet:
+  messages, bloodstains, ghosts, bells and summons. Linux and Windows players can play together.
+- **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 and Russian, 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.
+- **Game effects** on and off, **mods** and community **patches**, loaded without changing the
+  game files.
+- **Add to Steam** in one click (native or Flatpak Steam), and **Discord Rich Presence**.
+- **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.
 
 ## Requirements
 
-- Linux x86-64, a Vulkan 1.3 GPU. Tested: AMD RX 7800 XT with Mesa 26 (RADV).
-  The *New memory and translation model* mode is not tested on NVIDIA yet.
-  FSR 4 / 4.1.1 require shader Float16, Int8/Int16, integer dot products, linear compute
-  derivatives and extended storage image formats; FSR 4.1.1 additionally requires
-  `VK_VALVE_shader_mixed_float_dot_product`. Unsupported choices fall back to FSR 3.1
-  before the first frame and are disabled in the in-game menu.
-- Your decrypted game dump: the `CUSA03173` folder (eboot.bin, sce_module, ...), version 1.09.
-  A dumped update is a separate folder: copy it over the base game, replacing files. The base
-  game alone (1.00) crashes at start (guest offset 0x20348b8); the launcher and `run.sh` check
-  the executable and say what is missing (`BB_SKIP_GAME_CHECK=1` skips the check).
-- To build: GCC, CMake, Ninja, Python 3, glslang, SDL3, Vulkan headers and the libraries in
-  `shell.nix`. With [Nix](https://nixos.org) everything comes from `shell.nix` automatically.
+- 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.
 
-## Build and run
+## Getting started
+
+### AppImage
+
+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`.
+
+### From source
+
+On Arch Linux (or CachyOS, Manjaro…):
 
 ```bash
-git clone --recursive https://github.com/deadinside28/bloodborne_pc.git bbport && cd bbport
-bash build.sh                        # builds out/bb-probe and out/gpu/libbbgpu.so
-BB_GAME_DIR=/path/to/CUSA03173 bash run.sh
+sudo pacman -S --needed base-devel cmake ninja python python-gobject gtk4 libadwaita sdl3 \
+    vulkan-headers vulkan-icd-loader glslang spirv-headers spirv-cross ffmpeg boost fmt \
+    robin-map xxhash zydis miniz protobuf nlohmann-json openssl miniupnpc python-pillow ttf-dejavu
+paru -S magic_enum vulkan-memory-allocator xbyak   # from the AUR
+
+git clone --recursive https://github.com/ayozetr/bloodborne_linux
+cd bloodborne_linux
+bash build.sh
+python3 launcher/bbport_launcher.py   # or launcher/install-desktop.sh for a menu entry
 ```
 
-or the launcher (pick the game folder, settings, *Start*):
+With [Nix](https://nixos.org), `bash build.sh` gets every dependency from `shell.nix` by itself.
 
-```bash
-bash launcher/bb-launcher.sh         # launcher/install-desktop.sh adds it to the app menu
-```
+### Online play
 
-By default the game folder is expected next to the repository (`../CUSA03173`). Saves and the
-shader cache go to `user/` (the launcher lets you choose another folder); settings to
-`bbport.ini`. A gamepad is used through SDL3 (the launcher's *Controls → Controller* picks one
-when several are connected; `BB_GAMEPAD=<GUID or part of the name>`). The keyboard works too,
-also next to a connected gamepad (the Steam Deck always has one); both are remapped in the
-launcher (*Controls*). The character name is typed on the keyboard in a box over the game.
-The touchpad: its left half (Tab, Back/Select) opens the gestures, the right half (Backspace)
-the key items. There is no PSN: the *Play online / offline* screen is skipped and the game opens
-its main menu offline (a game patch; the launcher's *Game effects → Skip the “play online / offline” choice*,
-`BB_SKIP_NETWORK_CHOICE=0` shows it). With several monitors, *Screen → Monitor* in the launcher
-(`BB_DISPLAY=<number or part of the name>`) picks the one for the game.
+1. Register a shadNet account at [shadnet.shadps4.net](https://shadnet.shadps4.net).
+2. In the launcher, open **Online**, turn on **Play online** and enter your account name (not
+   your email) and password. **Test the connection**: all three servers should be reachable.
+3. Start the game and choose online at the title screen.
 
-**Resolution and preset changes:** for outputs other than 1080p (720p on the Steam Deck,
-1440p, 4K) the whole game renders at the preset's resolution, set by a patch at start — the
-fastest path. Changing the output or the preset in the in-game menu then needs *Apply and
-restart the game*. The *Live resolution changes* setting (launcher, in-game menu,
-`bbport.ini` `live_resolution=0|1|auto`; **off by default**) instead keeps the game at
-1080p internally and scales its render targets at run time, so 720p/1080p/1440p/4K and the
-presets switch without a restart. It costs more: the game then believes it renders 1080p
-and draws more (e.g. ~8× more small lights), and some targets are copied between sizes —
-use it on strong desktop GPUs only (`auto` turns it on for discrete GPUs with 8+ GB that are
-not pre-Turing NVIDIA). 1080p output and TAA always use the live path.
+Everyone in a session needs game version 1.09 and the same servers. Turn cheats off when you
+play with others.
 
-**TAA:** a separate native-resolution temporal AA mode in the launcher and overlay,
-switchable live without an FSR model. The saved FSR preset is restored when returning
-to FSR. FSR Native AA adds reconstruction on top of full-resolution rendering and can
-be slower than disabling AA. TAA also adds work compared with no temporal AA.
-The RCAS switch and the 0–2 sharpness control also work with TAA. Sharpening runs after
-temporal accumulation and leaves its history and HUD unchanged.
+Co-op connects the players directly over UDP. With ufw or firewalld on, the launcher's **Online**
+page says so and gives the commands: pin the port with `SHADPS4_P2P_PORT=3658` in the extra
+variables, open it (`sudo ufw allow 3658/udp`), and for UPnP let the router's answers in
+(`sudo ufw allow from <router> proto udp`).
 
-**Mods:** the launcher accepts separate loose-file mod folders (with `dvdroot_ps4/`, an extra
-wrapper folder, or the game folders such as `chr/` directly; file name case does not matter),
-with enable switches and load order. A sibling `CUSA03173-mods/` overlay also works.
-The original game is preserved; later mods override conflicting files.
-**Third-party patches:** shadPS4-format XML patch files in the data directory's `patches/`,
-switched on and off in the launcher. See [mods and patches](docs/MODS.md).
-**DLC:** put your add-on dumps in `user/addcont/<title id>/<entitlement label>/` (shadPS4's
-layout, e.g. `user/addcont/CUSA03173/SPEXPANSIONDLC03` for The Old Hunters): each folder there is
-reported to the game as an installed add-on.
+### DLSS
 
-**Launcher language:** Russian, English, Brazilian Portuguese or Simplified Chinese (follows the system language by default).
+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.
 
-**Free camera and game debug menu** (v1.09): enable the corresponding switches in the
-launcher or in-game menu and restart. Free camera uses Lance McDonald's
-[GoldHEN patch](https://github.com/GoldHEN/GoldHEN_Patch_Repository/blob/main/patches/xml/Bloodborne-Orbis.xml):
-hold Cross and press L3 to cycle modes (keyboard: hold Space and press Z). It needs no fonts
-and conflicts with *Enemy Control*.
-For the game debug menu, install `DbgFont14h.ccm` and `DbgFont14h.tpf` from
-[Debug Menu and XML Patch](https://www.nexusmods.com/bloodborne/mods/253) into the game's
-`dvdroot_ps4/font/` first. Startup rejects missing or empty font files instead of launching
-the unsafe patch. Open it with the left touchpad / Tab (with the debug menu on, the left half
-no longer opens the gestures); Backspace is the right touchpad.
-Touch coordinates are forwarded from SDL gamepads; Back/Select emulates a left click on
-pads without a touch surface. The port's settings menu remains Insert / L3+R3.
+### DLC
 
-GPU occlusion queries still use synthetic pixel counters (`PixelPipeStatDump`), and
-`IT_SET_PREDICATION` is unimplemented. Free camera allows visual investigation; it does
-not implement GPU occlusion culling.
+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.
 
-**Upscaler assets** (not included; FSR 3.1 needs none):
+### Add to Steam
 
-```bash
-bash tools/fetch_fsr4_assets.sh      # FSR 4 v07 (MIT, built from AMD's source by Q2RTX)
-# FSR 4.1.1, from your own AMD DLLs (e.g. OptiScaler's FSR4_LATEST), needs GE-Proton 10 or newer:
-bash tools/fsr4cap/build_assets.sh <amd_fidelityfx_upscaler_dx12.dll>
-```
+**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.
 
-**FSR 4.1.1 from your own DLL.** The easiest way is the launcher: *Upscaler → FSR 4.1.1 from your
-own AMD DLL → Choose DLL…*, then pick `amd_fidelityfx_upscaler_dx12.dll` version 4.1.x: from
-OptiScaler's `FSR4_LATEST` folder or from a game with FSR 4.1. That one file is enough: AMD's DLL
-exports the FidelityFX API itself, so no loader is needed (only a DLL without these exports would
-be recorded through `amd_fidelityfx_loader_dx12.dll`, and the launcher would ask for it). The DLL is checked at once,
-without a long capture; these do not fit: AMD's official FSR 4.0.x (e.g. Pragmata's 4.0.3 —
-AMD enables it on RDNA4 only, and under Proton it does not start on other GPUs) and community
-builds (4.0.2b, 4.1.1b and similar OptiScaler INT8 builds: another model and pass count). Then
-the DLL runs under Proton and is recorded at 20 sizes (progress in the row and in the *Log* tab;
-on RDNA4 a second time, for the FP8 variant),
-the passes are translated to SPIR-V, and FSR 4.1.1 is selected. The Proton build is picked
-automatically — the first under which the DLL enables FSR 4.1: GE-Proton 10 or newer,
-Proton-CachyOS, Proton Experimental (tested: GE-Proton 11, Proton-CachyOS 11, Experimental of
-October 2026; Steam's Proton 11.0 and GE-Proton 9 do not). It runs in the Steam runtime it
-requires (Steam installs it the first time any game runs with that Proton), or through
-umu-launcher when installed. On NixOS umu-launcher comes from `nix-shell` (downloaded the first
-time, ~1.7 GB); the AppImage runs the recording on the system itself, through the user's systemd
-(`systemd-run --user`), since the system's `/nix` is out of its sight. Recording on the Steam Deck is not verified yet; if the DLL does not
-enable FSR 4.1 there, build on a PC and copy the `fsr4_411` folder. The same from the command
-line: the launcher's (and the AppImage's) `--build-fsr411 <DLL>`.
+### Button prompts
 
-**DLSS (NVIDIA GeForce RTX).** NVIDIA's DLSS SDK is not included: check out
-[github.com/NVIDIA/DLSS](https://github.com/NVIDIA/DLSS) (`include/` and `lib/Linux_x86_64` are
-enough) and build with `DLSS_SDK_ROOT=/path/to/DLSS bash build.sh`. That also builds the bridge
-`out/libbbport_dlss.so` (`gpu/dlss_bridge`, the only code that uses the SDK) and copies NVIDIA's
-`libnvidia-ngx-dlss.so.<version>` next to `out/bb-probe`; the driver provides the rest. Then pick
-*DLSS* in the launcher or the in-game menu: the preset sets the render size, Native AA is DLAA.
-DLSS gets the inputs FSR 3.1 gets (scene color, depth, motion vectors, jitter). Without the
-libraries, on other GPUs or with `BB_DLSS=0` it is listed as unavailable, and a DLSS setting falls
-back to FSR 3.1.
+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.
 
-From source the script takes its tools from the system (MinGW GCC, CMake, Ninja, Python 3,
-SPIRV-Tools, Git) or from Nix; the AppImage has them prebuilt.
+## Credits
 
-**FP8 on RDNA4.** When vkd3d-proton offers FP8 cooperative matrices (RDNA4), the DLL runs
-another variant of its passes: other shaders and weights, other dispatch sizes. The build records
-both, INT8 into `fsr4_411/` and FP8 into `fsr4_411/fp8/`, and the game picks FP8 itself when the
-GPU has FP8 matrices (`VK_EXT_shader_float8`); the log says `Upscaler: FSR 4.1.1 replay, FP8 …`.
-`BB_FSR411_VARIANT=int8` forces INT8. Checked on an RX 7800 XT through vkd3d-proton's FP16
-emulation of FP8 (`BB_FSR4CAP_FP8=1` records it there too, `fp8emu/`): bit-exact with the DLL;
-**not yet run on RDNA4 hardware.**

-**AppImage** (Steam Deck): `bash build.sh && bash packaging/appimage.sh` →
-`dist/Bloodborne-bbport-x86_64.AppImage`; data in `~/.local/share/bbport`, `--play` starts the
-game without the launcher window (Game Mode). FSR 4.1.1 models are not packaged: build them with
-the launcher's button (see above); they go to `~/.local/share/bbport/fsr4_411`
-(`BB_PACKAGE_FSR411=1` bundles a local `fsr4_411` into an AppImage for your own devices). On the Steam Deck pick the 1280×720 output (the
-game is 16:9; on the 1280×800 screen it gets thin bars).
+Full list of components and licenses: [BBPORT.md](BBPORT.md#credits-and-licenses).
 
-**Adding the AppImage to Steam** (*Add a Non-Steam Game*) needs no options; the compatibility tool
-does not matter. (Steam preloads its overlay into every non-Steam game; the AppImage removes it
-before its own programs start, so the Steam overlay is not shown in the game.) Where Steam
-runs games without FUSE (NixOS: Steam's FHS sandbox; the AppImage then exits with *Cannot mount
-AppImage*), set the launch options to
+## License
 
-```
-TMPDIR=$HOME/.cache APPIMAGE_EXTRACT_AND_RUN=1 NO_CLEANUP=1 %command%
-```
-
-The AppImage then unpacks itself (~2 GB, `~/.cache/appimage_extracted_*`) on the first start
-(~10 s) and reuses that copy afterwards; a new AppImage version gets a new copy, the old one can
-be deleted. Without `TMPDIR` it would unpack into Steam's `/tmp`, which is in RAM there. Add
-` --play` after `%command%` to skip the launcher.
-
-**NVIDIA in the AppImage:** startup discovers the host's installed 64-bit NVIDIA Vulkan ICD
-and exposes its vendor libraries alongside the bundled AMD/Intel drivers. This keeps the
-NVIDIA userspace driver matched to the host kernel module. Standard Linux distributions keep
-these libraries under `/usr/lib*`; on NixOS the AppImage's internal `/nix/store` may hide them.
-In that case copy the NVIDIA libraries into an accessible directory and set
-`BB_NVIDIA_LIB_DIR=/path/to/libraries` (the NVIDIA manifest must also be accessible).
-With the host's NVIDIA driver the AppImage also passes the host's EGL vendor files, NVIDIA's
-first (`__EGL_VENDOR_LIBRARY_FILENAMES`; without them NVIDIA's ICD gave no `vkCreateInstance` on
-some hosts, #107; `BB_NVIDIA_EGL=0`: off). Explicit `VK_DRIVER_FILES`/`VK_ICD_FILENAMES` overrides are preserved. Diagnose drivers inside
-the package with:
-
-```bash
-./Bloodborne-bbport-x86_64.AppImage --vulkan-info 2>&1 | tee bbport-vulkan.log
-```
-
-A user reported successful startup with FSR 3 on a GTX 1060 6GB (Fedora 44, NVIDIA
-580.178.04); selecting FSR 4 caused a black window. Use FSR 3 on this configuration.
-
-MangoHud is bundled in the AppImage; enable its checkbox in the launcher. If MangoHud is also
-installed system-wide, or Steam's performance overlay is on (Steam Deck game mode), only one
-overlay is drawn (two drew doubled, offset text).
-When running from source, install MangoHud separately. A diagnostic launch with
-`VK_LOADER_LAYERS_DISABLE=~implicit~` also disables MangoHud.
-
-Useful variables: `BB_FRAME_STATS=1` (frame statistics, including a `Memory:` line: VRAM, GTT,
-RSS, images and guest blocks in VRAM), `BB_PC_MODEL=1` (the new memory and translation model,
-0, the old model as in 0.3, is the default), `BB_ANISO=N` (anisotropic filtering of scene textures; 16 by
-default, 0 = the game's own),
-`BB_GC_IDLE_SECONDS=N` / `BB_VRAM_IDLE_SECONDS=N` (how long unused textures / buffers stay in VRAM;
-20 / 60), `BB_BREADCRUMBS=0` (no GPU breadcrumbs; with them a GPU hang names the draw or dispatch
-it is stuck in), `BB_GPU_PROFILE=1` (GPU time per
-pass), `BB_FSR4_PROFILE=1` (GPU time per FSR 4 pass), `BB_UPSCALER=taa|fsr3|fsr4|fsr411|off|none`,
-`BB_FRAMES_AHEAD=N` (how many frames the GPU command thread may run ahead of the GPU; 1 by default,
-0 = unbounded), `BB_PRESENT_THREAD=0` (present on the vblank thread, as before),
-`BB_LIVE_RES=1` (live resolution changes instead of the startup patch for outputs other than 1080p),
-`BB_PAD_RECORD=file` / `BB_PAD_REPLAY=file` (record a route with F9, replay it in scripted tests),
-`BB_GC_BUDGET_MB=N` (texture cache budget, as on integrated GPUs), `BB_VRAM_LIMIT_MB=N` (the VRAM
-budget taken as at most N MiB: checks the behaviour of cards with little VRAM), `BB_ASYNC_PIPELINES=0`
-(new pipelines compile at once and the game waits; by default in the background), `BB_PRESENT_DUMP_TRIGGER=file`
-with `BB_PRESENT_DUMP_COUNT=N` (dump N consecutive presented frames),
-`BB_FSR411_VARIANT=int8|fp8|fp8emu` (FSR 4.1.1 variant; by default FP8 where the GPU has FP8
-matrices), `BB_READBACKS=0|1|2` (reads of GPU-written memory by the game: 1 by default, 2
-precise and slow, 0 off).

-## Roadmap
-
-- The new memory and translation model on by default on NVIDIA too, once it is as fast there;
-  the old model is removed after that.
-- 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.
-- 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.
-- 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.

+  of big prompts from the shared UI atlas (`atlas.dds`, scaled down to the game's atlas size).
+- `gesturetop.json`: the edits that turn the game's `menu/gesturetop.gfx` into the mod's.
+
+`scripts/menu_prompts.py` puts them into the player's own `menu/common.tpf.dcx` and
+`menu/gesturetop.gfx` at each start; `tools/extract_prompt_assets.py` rebuilds this folder from
