+Box64 lets you run x86_64 Linux programs (such as games) on non-x86_64 Linux systems, like ARM (host system needs to be 64-bit little-endian).
+
+You can find many Box64 videos on the [MicroLinux](https://www.youtube.com/channel/UCwFQAEj1lp3out4n7BeBatQ), [Pi Labs](https://www.youtube.com/channel/UCgfQjdc5RceRlTGfuthBs7g) or [The Byteman](https://www.youtube.com/channel/UCEr8lpIJ3B5Ctc5BvcOHSnA) YouTube channels.
+
+Since Box64 uses the native versions of some "system" libraries, like libc, libm, SDL, and OpenGL, it's easy to integrate and use with most applications, and performance can be surprisingly high in many cases. Take a look at thoses bench analysis for an example [here](https://box86.org/index.php/2021/06/game-performances/).
+
+Box64 integrates with DynaRec (dynamic recompiler) for the ARM64 and RV64 platform, providing a speed boost between 5 to 10 times faster than using only the interpreter. Some high level information on how DynaRec works can be found [here](https://box86.org/2021/07/inner-workings-a-high%e2%80%91level-view-of-box86-and-a-low%e2%80%91level-view-of-the-dynarec/).
+
+Some x64 internal opcodes use parts of "Realmode X86 Emulator Library", see [x64primop.c](src/emu/x64primop.c) for copyright details

+----
+
+Usage
+----
+
+There are a few environment variables to control the behaviour of Box64.
+
+See [here](docs/USAGE.md) for all the environment variables and what they do.
+
+Note: Box64's Dynarec uses a mechanism with Memory Protection and a SegFault signal handler to handle JIT code. In simpler terms, if you want to use GDB to debug a running program that use JIT'd code (like mono/Unity3D), you will still have many "normal" segfaults triggering. It is suggested to use something like `handle SIGSEGV nostop` in GDB to not stop at each segfault, and maybe put a breakpoint inside `my_memprotectionhandler` in `signals.c` if you want to trap SegFaults.

+
+Compiling/Installation
+----
+> Compilation instructions can be found [here](https://github.com/ptitSeb/box64/blob/main/docs/COMPILE.md) \
+> Instructions for installing Wine for Box64 can be found [here](https://github.com/ptitSeb/box64/blob/main/docs/X64WINE.md)
+
+----
+
+Version history/Change log
+----
+
+The change log is available [here](docs/CHANGELOG.md).
+
+----
+
+Notes about 32-bit platforms
+----
+
+Because Box64 works by directly translating function calls from x86_64 to host system, the host system (the one Box64 is running on) needs to have 64-bit libraries. Box64 doesn't include any 64-bit <-> 32-bit translation. 
+
+So understand that box64 will only run 64-bit linux binaries. For 32-bit binaries, you need box86 (with all the multiarch or proot trickery it implies on a 64-bit OS).
+Note that many installer (mojo setup based) will fall back to "x86" when detecting ARM64 OS, and so will try to use box86 for the setup, even if an x86_64 version exist. You can hack your way around with a fake "uname" that return "x86_64" when the argument is "-m"
+
+----
+
+Notes about Box64 configuration
+----
+
+Box64 now have configurations files. There are 2 files loaded. `/etc/box4.box64rc` and `~/.box64rc`. Both files have the same syntax, and is basicaly an ini files. Section in square brakets define the process name, and the rest is the env. var. to set. Looke at [Usage](USAGE.md) for detail on what parameters can be put. Box64 comes with a default file that should be installed for better stability. The file in in `system/box64.box64rc` and should be installed to `/etc/box64.box64rc` If, for some reason, you don't want to install that file here, at least copy it to `~/.box64rc` or some game may not function correctly.
+Note that the priority is: `~/.box64rc` > `/etc/box64.box64rc` > command line
+So, your settings in `~/.box64rc` may override the setting from your command line...
+
+----
+
+Notes about Unity game emulation
+----
+
+Running Unity games should just work, but you should also note that many Unity3D games require OpenGL 3+ which can be tricky to provide on ARM SBC (single-board computers). Also many newer Unity3D (like KSP) games use the BC7 compressed textures, which is not supported on many ARM integrated GPU.
+Hint: on Pi4, use `MESA_GL_VERSION_OVERRIDE=3.2` and with Panfrost use `PAN_MESA_DEBUG=gl3` to use higher profile if the game starts then quits before showing anything.
+
+----
+
+Notes about GTK programs
+----
+
+GTK libraries are now wrapped on box64, both gtk2 and gtk3.
+
+----
+
+Notes about Steam
+----
+
+Note that Steam is a hybrid 32-bit / 64-bit. You NEED box86 to run Steam, as the client app is a 32-bit binary. It also uses a 64-bit local server binaries, and that steamwebhelper process is now mandatory, even on the "small mode". And that process will eat lots of memory. So machine with less the 6Gb of RAM will need a swapfile to use Steam.
+
+----
+
+Notes about Wine
+----
+
+Wine64 is supported on box64. Proton too. Be aware that 64-bit Wine also includes 32-bit components, to be able to run 32-bit Windows programs. The 32-bit apps will need box86 and will not run without it. On a system where both box64 and box86 are present and working, a wine 64-bit setup can run both 32-bit and 64-bit Windows programs (just use `wine` and `wine64` respectively).
+Note that the new 32-bit PE in 64-bit processes that the Wine team is currently implementing in Wine 7.+ is now supported, but the support is quite young so there might be some residual issues.
+
+----
+
+Notes about Vulkan
+----
+
+Box64 wraps Vulkan libraries, but note that it as mostly been tested with an AMD RX550 card and on the Freedreno driver, so some extensions may be missing depending on your graphics card.
+
+----
+

+
+Box64 可以在非 x86_64 Linux 系统（比如 ARM64）上运行 x86_64 Linux 程序（比如游戏），注意主机系统需要是 64 位小端。
+
+您可以在 [MicroLinux](https://www.youtube.com/channel/UCwFQAEj1lp3out4n7BeBatQ)、[Pi Labs](https://www.youtube.com/channel/UCgfQjdc5RceRlTGfuthBs7g) 和 [The Byteman](https://www.youtube.com/channel/UCEr8lpIJ3B5Ctc5BvcOHSnA) YouTube 频道上找到许多 Box64 视频。
+
+由于 Box64 使用一些“系统”库的原生版本，如 libc、libm、SDL 和 OpenGL 等，因此很容易与大多数应用程序集成和使用，并且在许多情况下性能会相当不错。可以在[这里](https://box86.org/index.php/2021/06/game-performances/)查看一些性能测试的样例。
+
+Box64 集成了适用于 ARM64 和 RV64 平台的 DynaRec（动态重编译器），速度可以比纯解释模式快 5 到 10 倍。可以在[这里](https://box86.org/2021/07/inner-workings-a-high%E2%80%91level-view-of-box86-and-a-low%E2%80%91level-view-of-the-dynarec/)找到有关 DynaRec 工作原理的一些信息。

+使用方法
+----
+
+有若干环境变量可以控制 Box64 的行为。
+
+可在[这里](docs/USAGE.md)查看所有环境变量及其作用。
+
+注意：Box64 的 Dynarec 使用具有内存保护和段错误信号处理的机制来执行 JIT 代码。所以，如果想使用 GDB 调试使用 JIT 代码的程序（如 Mono/Unity3D），这会触发许多“正常”的段错误。建议在 GDB 中使用类似 `handle SIGSEGV nostop` 来防止它每个段错误处停止。如果你想捕获段错误，可以在 `signals.c` 的 `my_memprotectionhandler` 中设置断点。

+
+32位平台的注意事项
+----
+
+因为 Box64 的工作原理是直接将函数调用从 x86_64 转换为主机系统，所以主机系统（运行 Box64 的系统）需要有 64 位库。Box64 不包含任何 64 位 <-> 32 位的转换。
+
+所以 box64 只能运行 64 位的 Linux 二进制。对于 32 位二进制则需要使用 box86 来运行（它在 64 位操作系统上使用了 multiarch 和 proot 等技巧来实现运行）。请注意，许多（基于 mojo 的）安装程序在检测到 ARM64 操作系统时将回退到 “x86”，因此即使存在 x86_64 版本，也会尝试使用 box86。这时你可以使用一个假的 `uname` ，并使它在运行参数为 `-m` 时返回 `x86_64`。
+
+----
+
+关于 Unity 游戏模拟的注意事项
+----
+
+运行 Unity 游戏应该没什么问题，但还应该注意，许多 Unity3D 游戏需要 OpenGL 3+，这在 ARM SBC 上可能会比较棘手。同时许多较新的 Unity3D游戏（如 KSP）也使用 BC7 压缩纹理，很多 ARM 的集成显卡并不支持。
+
+> 提示：如果游戏开始后没有显示任何东西就退出了，在 Pi4 上可以使用 `MESA_GL_VERSION_OVERRIDE=3.2`，在 Panfrost 上则可以使用 `PAN_MESA_DEBUG=gl3` 来使用更高的配置。
+
+----
+
+关于GTK程序的注意事项
+----
+
+box64 封装了 GTK，包括 gtk2 和 gtk3。
+
+----
+
+关于 Steam 的注意事项
+----
+
+请注意，Steam 是 32/64 位混合的应用，所以你需要 box86 才能运行，因为客户端应用程序是 32 位的。它还使用 64 位本地服务器，它的 steamwebhelper 无法被关闭（即使是在最小模式）而且会吃掉大量的内存。对于内存小于 6 GB 的机型，你将会需要创建 swapfile 来运行 Steam。
+
+----
+
+关于 Wine 的注意事项
+----
+
+box64 支持 Wine64，Proton 应该也能运行。请注意，64 位 Wine 包含有 32 位组件，以便能够运行 32 位 Windows 程序。32 位应用程序需要 box86，否则无法运行。在 box64 和 box86 都存在并工作的系统上，64 位的 Wine 可以同时运行 32 位和 64 位 Windows 程序（分别使用 `wine` 和 `wine64`）。请注意，目前在 Wine 7.+ 中实现的 Wine 时间在 64 位进程中的新 32bit PE 尚不支持。我测试了 Wine 7.5 64 位可以正常工作，但是更新的版本可能还不行。
+
+----
+
+关于 Vulkan 注意事项
+----
+
+Box64 封装了 Vulkan 库，但请注意，它仅在 RX550 显卡上进行过测试，因此根据您的显卡，某些扩展可能会丢失。
+
+----

+
+Box64 дозволяє запускати x86_64 Linux програми (наприклад, ігри) на системах Linux відмінних від x86_64, наприклад ARM (хост-система має мати 64-розрядний порядок редагування).
+
+Ви можете знайти багато відео про Box64 в YouTube каналах [MicroLinux](https://www.youtube.com/channel/UCwFQAEj1lp3out4n7BeBatQ), [Pi Labs](https://www.youtube.com/channel/UCgfQjdc5RceRlTGfuthBs7g) або [The Byteman](https://www.youtube.com/channel/UCEr8lpIJ3B5Ctc5BvcOHSnA)
+
+Оскільки Box64 використовує рідні версії деяких «системних» бібліотек, таких як libc, libm, SDL і OpenGL, його легко інтегрувати та використовувати з більшістю програм, а продуктивність у багатьох випадках може бути напрочуд високою. Подивіться на цей стендовий аналіз для прикладу [тут](https://box86.org/index.php/2021/06/game-performances/).
+
+Box64 інтегрується з DynaRec (динамічний рекомпілятор) для платформ ARM64 і RV64 забезпечуючи підвищення швидкості в 5-10 разів, ніж використання лише інтерпретатора. Деякі високорівневі відомості про те, як працює DynaRec, можна знайти [тут](https://box86.org/2021/07/inner-workings-a-high%e2%80%91level-view-of-box86-and-a-low%e2%80%91level-view-of-the-dynarec/).
+
+Деякі внутрішні коди операцій x64 використовують частини «Бібліотеки емулятора Realmode X86», дивіться [x64primop.c](src/emu/x64primop.c) для детальної інформації про авторські права.

+
+Є кілька змінних середовища для керування поведінкою Box64.
+
+Дивіться [тут](docs/USAGE.md) для перегляду всіх змінних середовища та того, що вони роблять.
+
+Примітка: Dynarec від Box64 використовує механізм із захистом пам’яті та обробником сигналу помилки сегментів для обробки JIT коду. Простіше кажучи, якщо ви хочете використовувати GDB для налагодження запущеної програми, яка використовує JIT-код (наприклад, mono/Unity3D), ви все одно матимете багато «звичайних» помилок сегментів. Пропонується використовувати щось на зразок `handle SIGSEGV nostop` в GDB, щоб не зупинятися на кожній помилці сегмента, і, можливо, поставити точку зупину всередині `my_memprotectionhandler` в `signals.c`, якщо ви хочете перехопити помилки сегментів.

+
+Примітки щодо 32 бітних платформ
+----
+Оскільки Box64 працює шляхом прямого перекладу викликів функцій з x86_64 на хост-систему, хост-система (та, на якій працює Box64) повинна мати 64-розрядні бібліотеки. Box64 не містить 64-біт <-> 32-біт перекладу.
+
+Також розумійте що Box64 запускатиме лише 64-розрядні двійкові Linux файли. Для 32-розрядних двійкових файлів вам потрібен Box86 (з усіма хитрощами з мультиархітектурною системою або корінними правами). Зауважте, що багато інсталяторів (на основі mojo) повертаються до "x86" при виявленні ОС ARM64, і тому намагатимуться використовувати Box86 для налаштування, навіть якщо існує версія x86_64. Ви можете зламати свій шлях за допомогою фальшивого "uname", який повертає "x86_64", коли аргумент "-m"
+
+----
+
+Примітки щодо конфігурації Box64
+----
+
+Обидва файли мають однаковий синтаксис і в основному є файлами ini. Розділ у квадратних дужках визначає назву процесу, а решта — встановлють змінну середовища. Подивіться [використання](USAGE.md), щоб дізнатися, які параметри можна завдати. Box64 поставляється з файлом за замовчуванням, який слід встановити для кращої стабільності. Файл знаходиться в `system/box64.box64rc` і має бути встановлен в `/etc/box64.box64rc`. Якщо з певних причин ви не хочете встановлювати цей файл у `/etc`, принаймні скопіюйте його в `~/.box64rc` або гра може не працювати належним чином. Зауважте, що пріоритетом є: `~/.bashrc` > `/etc/box64.box64rc` > командний рядок
+Таким чином, ваші налаштування в `~/.bashrc` можуть замінити налаштування з вашого командного рядка...
+
+----
+
+Примітки щодо емуляції ігор Unity
+----
+
+Запуск ігор Unity має працювати, але ви також повинні зауважити, що для багатьох ігор Unity3D потрібен OpenGL 3+, який може бути складно забезпечити на ARM SBC (одноплатних комп’ютерах). Крім того, багато нових ігор Unity3D (наприклад, KSP) використовують стиснуті текстури BC7, які не підтримуються багатьма інтегрованими GPU ARM.
+Підказка: в Pi4 використовуйте `MESA_GL_VERSION_OVERRIDE=3.2`, а в Panfrost — `PAN_MESA_DEBUG=gl3`, щоб використовувати вищий профіль, якщо гра запускається, а потім завершується, перш ніж щось показує.
+
+----
+
+Примітки щодо програм GTK
+----
+
+Бібліотеки GTK2 і GTK3 тепер використовуються в Box64.
+
+----
+
+Примітки щодо Steam
+----
+
+Зауважте, що Steam є гібридом 32-біт / 64-біт. Вам ПОТРІБЕН box86, щоб запустити Steam, оскільки клієнта є 32-розрядною двійковою програмою. Він також використовує 64-розрядні двійкові файли локального сервера, і цей процес steamwebhelper тепер є обов’язковим навіть у «малому режимі». І цей процес з’їсть багато оперативної пам’яті, таким чином машині з 6 Гб оперативної пам’яті знадобиться файл підкачки для використання Steam.
+
+----
+
+Примітки щодо Wine
+----
+
+Wine64 підтримується Box64, Proton теж. Майте на увазі, що 64-розрядний Wine також містить 32-розрядні компоненти щоб мати можливість запускати 32-розрядні програми Windows. Для 32-розрядних програм потрібен Box86, і вони не працюватимуть без нього. У системі, де присутні і працюють Box64, і Box86, 64-розрядне встановлення Wine може запускати як 32-розрядні, так і 64-розрядні програми Windows (просто використовуйте `wine` і `wine64` відповідно).
+Зауважте, що новий 32-бітний PE в 64-бітному процесі, який Wine зараз реалізує у Wine 7+ тепер підтримується, але підтримка є досить молодою тому можуть виникнути деякі проблеми.
+
+----
+
+Примітки щодо Vulkan
+----
+
+Box64 використовує бібліотеки Vulkan, але зауважте що він тестувався з картою AMD Radeon RX550 і драйвером Freedreno, тому деякі розширення можуть бути відсутні залежно від вашої відеокарти.

+Compiling/Installing
+----
+
+### Debian-based Linux 
+You can use [@ryanfortner](https://github.com/ryanfortner)'s apt repository to install precompiled box64 debs, updated every 24 hours. 
+
+```
+sudo wget https://ryanfortner.github.io/box64-debs/box64.list -O /etc/apt/sources.list.d/box64.list
+wget -qO- https://ryanfortner.github.io/box64-debs/KEY.gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/box64-debs-archive-keyring.gpg
+sudo apt update && sudo apt install box64-arm64 -y
+```
+
+Alternatively, you can generate your own package using the [instructions below](https://github.com/ptitSeb/box64/blob/main/docs/COMPILE.md#debian-packaging). 
+
+----
+
+### The general approach is:
+```
+git clone https://github.com/ptitSeb/box64
+cd box64
+mkdir build; cd build; cmake .. ${OPTIONS}
+make -j4  
+sudo make install
+```
+If it's the first install, you also need:
+```
+sudo systemctl restart systemd-binfmt
+```
+- You can use `make -j1`, `make -j2` to prevent running out of memory
+- You can also add `-DBAD_SIGNAL=ON` to the cmake command if you are on Linux Kernel mixed with Android, like on RK3588.
+
+#### For Instance, if you want to build box64 for Generic ARM64 Linux platforms, it would look like this:
+```
+git clone https://github.com/ptitSeb/box64
+cd box64
+mkdir build; cd build; cmake .. -D ARM_DYNAREC=ON -D CMAKE_BUILD_TYPE=RelWithDebInfo
+make -j4
+sudo make install
+sudo systemctl restart systemd-binfmt
+```
+----
+
+#### for RK3399
+
+Using a 64bit OS:
+```
+-D RK3399=1 -D CMAKE_BUILD_TYPE=RelWithDebInfo
+```
+
+#### for RK3588 / RK3588S
+
+Using a 64bit OS:
+```
+-D RK3588=1 -D CMAKE_BUILD_TYPE=RelWithDebInfo
+```
+
+#### for Raspberry Pi 3
+
+Warning, you need a 64bit OS:
+
+If building on the Pi, you will also need a large swap (3 GB+)
+[optionally reduce GPU memory to a minimum (e.g. 16 MB) using `raspi-config`
+(and reboot) before starting the build]:
+
+You can use e.g. '`make -j4`' to speed up the build, but on a Pi 3 with 1GB memory you will likely
+run out of memory at some point and need to run the build again.
+Still, this can be faster if your build is attended.
+
+```
+-D RPI3ARM64=1 -D CMAKE_BUILD_TYPE=RelWithDebInfo
+```
+
+#### for Raspberry Pi 4
+
+Warning, you need a 64bit OS:

+If you encounter some linking errors, try using `NOLOADADDR=ON` (`cmake -D NOLOADADDR=ON; make -j$(nproc)`).
+
+----
+
+### Use ccmake
+
+Alternatively, you can **use the curses-bases ccmake (or any other gui frontend for cmake)** to select wich platform to use interactively.
+
+### Customize your build
+
+#### Use ccache if you have it
+
+Add `-DUSE_CCACHE=1` if you have ccache (it's better if you plan to touch the sources)
+
+#### To have some debug info
+
+The `-DCMAKE_BUILD_TYPE=RelWithDebInfo` argument makes a build that is both optimized for speed, and has debug information embedded. That way, if you have a crash or try to analyse performance, you'll have some symbols.
+
+#### To have a Trace Enabled build 
+
+To have a trace enabled build (***the interpreter will be slightly slower***), add `-DHAVE_TRACE=1`. But you will need to have the [Zydis library](https://github.com/zyantific/zydis) in your `LD_LIBRARY_PATH` or in the system library folders at runtime. Use version v3.2.1, as later version changed the API and will no longer work with box64
+
+#### To have ARM Dynarec
+
+Dynarec is only available on ARM (for the meantime), Activate it by using `-DARM_DYNAREC=1`.
+
+#### To have a build using less memory
+
+You can use `-DSAVE_MEM` to have a build that will try to save some memory. It's, for now, only increasing the jumptable from 4 level to 5 levels. The added granularity avoid wasting space, but the 1 level more to the jumptable means there is on read from memory more when jumping between blocks.
+
+#### Not building from a git clone
+
+If you are not building from a git clone (for example, downloading a release source code zip from github), you need to use `-DNOGIT=1` from cmake to be able to build (box64 uses git SHA1 to show last commit in version number).
+
+#### Use faster linker
+
+You need to add `-DWITH_MOLD=1` if GNU ld is extremely slow. Then run `mold -run make -j4` to build (make sure [Mold](https://github.com/rui314/mold) is installed).
+
+----
+
+Testing
+----
+A few tests are included with box64.
+
+They can be launched using the `ctest` command.
+
+The tests are very basic and only tests some functionality for now.
+
+----
+
+Debian Packaging
+----
+Box64 can also be packaged into a .deb file ***using the source code zip from the releases page*** with `DEB_BUILD_OPTIONS=nostrip dpkg-buildpackage -us -uc -nc`. Configure any additional cmake options you might want in `debian/rules`.

+Usage
+----
+
+There are many environment variables to control Box64 behaviour.

+ * 1 : Launch `gdb` when a segfault, bus error or illegal instruction signal is trapped, attached to the offending process and go in an endless loop, waiting.
+ When in gdb, you need to find the correct thread yourself (the one with `my_box64signalhandler` in is stack)
+ then probably need to `finish` 1 or 2 functions (inside `usleep(..)`) and then you'll be in `my_box64signalhandler`,

+# Installing Wine64
+Running Wine64/Wine with Box64/Box86 allows x64/x86 Windows programs to run on 64-bit ARM Linux devices.
+ - Box64 needs `wine-amd64` to be installed **manually** on ARM64 (aarch64) devices.  This will run 64-bit Windows programs (aka x86_64).
+ - Box86 needs `wine-i386` to be installed **manually** on ARM32 (armhf) devices (or on ARM64 with multiarch or chroot).  This will run 32-bit Windows programs (aka x86).
+ - _Note that `wine:arm64` and `wine:armhf` will not work with Box64/Box86. Your device's package manager might try to install those if you ask it to install wine._
+
+See installation steps below (in the [Examples](#examples) section).
+
+## Overview
+The general procedure for installing Wine64 & Wine for Box64 & Box86 is to...
+ - Download all the install files for the version of Wine you wish to install
+ - Unzip or dpkg the install files into one folder
+ - Move that folder to the directory that you wish Wine to run from (often `~/wine/` by default)
+ - Go to `/usr/local/bin` and make symlinks or scripts that will point to your main wine binaries.
+ - Boot wine to create a new wineprefix.
+ - Download winetricks (which is just a complicated bash script), make it executable, then copy it to `/usr/local/bin`.
+
+## Examples
+### Installing Wine64 & Wine for Box64 & Box86 on Raspberry Pi OS from WineHQ .deb files
+_Links from the [WineHQ repo](https://dl.winehq.org/wine-builds/debian/dists/)_
+
+This install method allows you to install different versions of Wine64/Wine.  You may install any version/branch of Wine that you wish.
+```
+	# NOTE: Can only run on aarch64 (since box64 can only run on aarch64)
+	# box64 runs wine-amd64, box86 runs wine-i386.
+
+	### User-defined Wine version variables ################
+	# - Replace the variables below with your system's info.

+
+## Installing winetricks
+Winetricks is a bash script which makes it easier to install & configure any desired Windows core system software packages which may be dependencies for certain Windows programs.  You can either install it with `apt`, or manually using the steps below.
+
+```
+sudo apt-get install cabextract -y                                                                   # winetricks needs this installed
+sudo mv /usr/local/bin/winetricks /usr/local/bin/winetricks-old                                      # Backup old winetricks
+cd ~/Downloads && wget https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks # Download
+sudo chmod +x winetricks && sudo mv winetricks /usr/local/bin/                                       # Install
+```
+
+Whenever we run winetricks, we must tell Box86 to supress its info banner, otherwise winetricks will crash.  Box86's info banner can be suppressed using the `BOX86_NOBANNER=1` environment variable before invoking winetricks (example: `BOX86_NOBANNER=1 winetricks`).
+
+If `apt` installed a desktop menu shortcut for winetricks (or if you make your own desktop shortcut for winetricks) then you may need to edit that shortcut to include Box86's BOX86_NOBANNER=1 env var.  With your favorite text editor, edit `/usr/share/applications/winetricks.desktop` and change `Exec=winetricks --gui` to `Exec=env BOX86_NOBANNER=1 winetricks --gui`.
+
+## Example commands
+Creating a 64-bit wineprefix:
+`wine64 wineboot` or `wine wineboot` (wineprefix is created in `~/.wine/`)
+`WINEPREFIX="$HOME/prefix64" wine wineboot` (wineprefix is created in `~/prefix64/`) _Note: You will need to invoke `WINEPREFIX="$HOME/prefix64"` before every command to use this wineprefix._
+
+Creating a 32-bit wineprefix:
+`WINEARCH=win32 wine wineboot` (wineprefix is created in `~/.wine/`)
+
+Fore-quitting wine:
+`wineserver -k`
+
+Running Wine Configuration:
+`winecfg`
+
+Using winetricks:
+`winetricks -q corefonts vcrun2010 dotnet20sp1`  
+_This command will silently install three packages in series: Windows core fonts, VC++ 2010 Runtimes, and .NET 2.0 SP1.  `-q` is the "install silent/quiet" command._
+
+Invoking Box86's logging features (with `BOX86_LOG=1` or similar) will cause winetricks to crash.
+
+For a list of all the different Windows packages & libraries that winetricks can help you install, run `winetricks list-all`  
+
+## Other notes
+
+### Wineprefixes (and Wine initialization)
+When you first run or boot Wine (`wine wineboot`), Wine will create a new user environment within which to install Windows software.  This user environment is called a "wineprefix" (or "wine bottle") and is located (by default) in `~/.wine` (note that Linux folders with a `.` in front of them are "hidden" folders).  Think of a wineprefix as Wine's virtual 'harddrive' where it installs software and saves settings.  Wineprefixes are portable and deletable.  For more Wine documentation, see [WineHQ](https://www.winehq.org/documentation).
+
+If you at any point corrupt something inside your default wineprefix, you can start "fresh" by deleting your `~/.wine` directory (with the `rm -rf ~/.wine` command) and boot wine again to create a new default wineprefix.
+
+### Transplanting wineprefixes
+If software isn't installing in Wine with Box86, but is installing for you in Wine on a regular x86 Linux computer, you can copy a wineprefix from your x86 Linux computer to the device you're running Box86 on. This is most easily done by tarring the `~/.wine` folder on your x86 Linux computer (`tar -cvf winebottle.tar ~/.wine`), transferring the tar file to your device, then un-tarring the tar file (`tar -xf winebottle.tar`) on your device running Box86 & Wine. Tarring the wineprefix preserves any symlinks that are inside it.
+
+### Swapping out different versions of Wine
+Some versions of Wine work better with certain software. It is best to install a version of Wine that is known to work with the software you would like to run. There are three main development branches of Wine you can pick from, referred to as wine-stable, wine-devel, and wine-staging. _Note that the wine-staging branch requires extra installation steps on Raspberry Pi._
+
+Your entire Wine installation can reside within a single folder on your Linux computer. TwisterOS assumes that your Wine installation is located inside the `~/wine/` directory. The actual directory where you put your `wine` folder doesn't matter as long as you have symlinks within the `/usr/local/bin/` directory which point to the `wine` folder so that Linux can find Wine when you type `wine` into the terminal).
+
+You can change which version of Wine you are running simply by renaming your old `wine` and `.wine` folders to something else, then putting a new `wine` folder (containing your new version of Wine) in its place. Running `wine wineboot` again will migrate a wineprefix from an older version of Wine to be usable by the newer version of Wine you just installed.  You can check which version of Wine you're running with the `wine --version` command.

+=head1 NAME
+
+box64 - Linux Userspace x86_64 Emulator with a twist
+
+=head1 SYNOPSIS
+
+B<box64> [B<--help>] [B<--version>] I<executable>
+
+=head1 DESCRIPTION
+
+B<Box64> lets you run x86_64 Linux programs (such as games) on non-x86_64 Linux
+systems, like ARM (host system needs to be 64-bit little-endian). Since B<Box64>
+uses the native versions of some "system" libraries, like libc, libm, SDL, and
+OpenGL, it's easy to integrate and use with most applications, and performance
+can be surprisingly high in many cases. B<Box64> integrates with DynaRec (dynamic
+recompiler) for the ARM64 platform, providing a speed boost between 5 to 10
+times faster than using only the interpreter.
+

+basically an ini files. Section in square brackets define the process name, and
+the rest is the environment variable. B<Box64> comes with a default file that
+should be installed for better stability. Note that the priority is:
+F<~/.bashrc> > F</etc/box64.box64rc> > command line So, your settings in
+F<~/.bashrc> may override the setting from your command line. Example:

+
+    * 0 : Don't optimize CALL/RET, use Jump Table for boths (Default)
+    * 1 : Try to optimized CALL/RET, skipping the use of the JumpTable when possible (will crash if blacks are invalidate, so probably incompatible with JIT/Dynarec)
+
+=item B<BOX64_DYNAREC_HOTPAGE>=I<0|1-255>
+
+Handling of HotPage (Page beeing both executed and writen)
+
+    * 0 : Don't track hotpage

+
+Handling of SSE Flush to 0 flags

+=item B<BOX64_LIBGL>=I<libXXXX|/PATH/TO/libGLXXX>
+
+You can also use B<SDL_VIDEO_GL_DRIVER>
+
+     * libXXXX set the name for libGL (defaults to libGL.so.1).
+     * /PATH/TO/libGLXXX : Sets the name and path for libGL
+
+=item B<BOX64_EMULATED_LIBS>=I<XXXX[:YYYY:...]>
+
+Force lib XXXX (and YYYY...) to be emulated (and not wrapped) Some games uses
+an old version of some libraries, with an ABI incompatible with native version.
+Note that LittleInferno for example is auto detected, and libvorbis.so.0 is
+automatical added to emulated libs, and same for Don't Starve (and Together /
+Server variant) that use an old SDL2 too
+
+=item B<BOX64_ALLOWMISSINGLIBS>=I<0|1>
+
+Allow Box64 to continue even if a library is missing.
+
+    * 0 : Box64 will stop if a library cannot be loaded. (Default.)
+    * 1 : Continue even if a needed library cannot be loaded. Unadvised, this will, in most cases, crash later on.
+
+=item B<BOX64_PREFER_WRAPPED>=I<0|1>
+
+Box64 will use wrapped libs even if the lib is specified with absolute path
+
+    * 0 : Try to use emulated libs when they are defined with absolute path  (Default.)
+    * 1 : Use Wrapped native libs even if path is absolute
+
+=item B<BOX64_PREFER_EMULATED>=I<0|1>
+
+Box64 will prefer emulated libs first (execpt for glibc, alsa, pulse, GL,
+vulkan and X11
+
+   * 0 : Native libs are prefered (Default.)
+   * 1 : Emulated libs are prefered (Default for program running inside pressure-vessel)
+
+=item B<BOX64_CRASHHANDLER>=I<0|1>
+
+Box64 will use a dummy crashhandler.so library
+
+    * 0 : Use Emulated crashhandler.so library if needed
+    * 1 : Use an internal dummy (completly empty) crashhandler.so library (defaut)
+
+=item B<BOX64_MALLOC_HACK>=I<0|1|2>
+
+How Box64 will handle hooking of malloc operators
+
+    * 0 : Don't allow malloc operator to be redirected, rewriting code to use regular function (Default)
+    * 1 : Allow malloc operator to be redirected (not advised)
+    * 2 : Like 0, but track special mmap / free (some redirected functions were inlined and cannot be redirected)
+
+=item B<BOX64_NOPULSE>=I<0|1>
+
+Disables the load of pulseaudio libraries.
+
+    * 0 : Load pulseaudio libraries if found. (Default.)
+    * 1 : Disables the load of pulse audio libraries (libpulse and libpulse-simple), both the native library and the x86 library
+
+=item B<BOX64_NOGTK>=I<0|1>
+
+Disables the loading of wrapped GTK libraries.
+
+    * 0 : Load wrapped GTK libraries if found. (Default.)
+    * 1 : Disables loading wrapped GTK libraries.
+
+=item B<BOX64_NOVULKAN>=I<0|1>
+
+Disables the load of vulkan libraries.
+
+    * 0 : Load vulkan libraries if found.
+    * 1 : Disables the load of vulkan libraries, both the native and the i386 version (can be useful on Pi4, where the vulkan driver is not quite there yet.)
+
+=item B<BOX64_FUTEX_WAITV>=I<0|1>
+
+Use of the new fuext_waitc syscall
+
+     * 0 : Do not try to use it, return unsupported (default for BAD_SIGNAL build)
+    * 1 : let program use the syscall if the host system support it (Default for other build)
+
+=item B<BOX64_BASH>=I<yyyy>
+
+Define x86_64 bash to launch script. Will use yyyy as x86_64 bash to launch
+script. yyyy needs to be a full path to a valid x86_64 version of bash
+
+=item B<BOX64_JITGDB>=I<0|1|2>
+
+    * 0 : Just print the Segfault message on segfault (default)
+    * 1 : Launch `gdb` when a segfault, bus error or illegal instruction signal is trapped, attached to the offending process and go in an endless loop, waiting. When in gdb, you need to find the correct thread yourself (the one with `my_box64signalhandler` in is stack) then probably need to `finish` 1 or 2 functions (inside `usleep(..)`) and then you'll be in `my_box64signalhandler`, just before the printf of the Segfault message. Then simply  `set waiting=0` to exit the infinite loop.
+    * 2 : Launch `gdbserver` when a segfault, bus error or illegal instruction signal is trapped, attached to the offending process, and go in an endless loop, waiting. Use `gdb /PATH/TO/box64` and then `target remote 127.0.0.1:1234` to connect to the gdbserver (or use actual IP if not on the machine). After that, the procedure is the same as with ` BOX64_JITGDB=1`. This mode can be usefullwhen programs redirect all console output to a file (like Unity3D Games)

+# The directory containing all PKGBUILDs for BOX64
+## FAQ
+### 1. How to use it?
+Just download the `PKGBUILD-<your-platform>` (no need to download the whole repository), go to directory where you downloaded and type:
+```sh
+mv ./PKGBUILD-<your-platform> ./PKGBUILD
+# use the below line if you need a DEBUG build
+# sed -i 's/RelWithDebInfo/Debug/g' ./PKGBUILD
+cd ..
+makepkg -si
+```
+This will copy the PKGBUILD for your platform (where you type your platform name instead of `<your-platform>`), build it and install the PKGBUILD on 64-bit Archlinux ARM.
+
+In the future, I might try to do an unified PKGBUILD for all platforms that will recognize your platform automatically.
+
+### 2. What platforms are currently supported.
+All specified in [COMPILE.md](../docs/COMPILE.md) except for LARCH64, PPC64LE and SW64.
+
+### 3. Any advantages with this solution?
+This might give you some advantages like:
+- automatic updates (with some AUR frontends like [`pamac-aur`](https://aur.archlinux.org/packages/pamac-aur/) or [`yay`](https://aur.archlinux.org/packages/yay));
+- easily uninstall with `pacman -R` when no needed (no need other scripts nor Makefile to do this);
+- your `box64` installation is recognized as a package (where it wasn't when installing with `make install`).
+
+
+### Note: You can use [makedeb](https://github.com/makedeb/makedeb) (or) [pkgbuild2spec](https://github.com/prozum/pkgbuild2spec) to compile box64 to .deb or .rpm installer files.
