Running

Both platforms below need the original game data; this repository ships none (see Legal).

Linux (AppImage)

Copy the data from a legally obtained Carmageddon II install in:

~/.local/share/carpocalypse2/DATA/     game data (required)
~/.local/share/carpocalypse2/MUSIC/    CD audio as Track02.ogg ... Track08.ogg (optional)

Android (APK)

Push the original game data onto the device:

adb push /path/to/C2/DATA \
  /sdcard/Android/data/com.carpocalypse2.game/files/DATA

The app requests no storage permission and can only read its own app-specific directory, which is the path above. The data must be pushed after the app has been launched at least once (that creates the directory). Note that some Android 11+ devices refuse adb access to Android/data entirely; an in-app importer for those devices is planned, and is the only blocker for a permissionless data setup. Start the app. Touch input is passed to the game as the pointer, so menus and the original controls are usable without a mouse; the app runs in sensor-landscape.

Debug-signed builds can only be replaced with adb install -r while the signature still matches — reinstalling over a future release-signed build requires uninstalling first.

Build requirements

• SDL3
• glslang: compiles BRender's GLSL shaders to SPIR-V for the default SDL3 GPU renderer (glslang or glslangValidator must be on PATH when CMake configures)
• 32-bit x86 compiler:
  • MSVC 11.0 (Visual Studio 97 SP3) compiler for matching build, or
  • a modern MinGW or MSVC toolchain
• DirectX SDK: we need dinput and dxguid.
  • MinGW provides these libraries out-of-the box
  • MSVC does not ship with a DirectX SDK: this time-period correct version on archive.org works perfect.
• libtiff: this library is used to convert tiff images to BRender pixelmaps

Linux

sudo pacman -S cmake glslang sdl3

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make

On macOS install glslang with brew install glslang; on Windows put glslang.exe/glslangValidator.exe from a glslang release on PATH before configuring CMake.

Goals

• Exact same behavior as the original
• Matching binary

Credits

• bojan1986819 vita port and more functions matches
• foone for BRender source code
• madebr for initial decompilation effort

Contributing

Yes this was used AI (free, non-paid agent models), so vibecoded PRs are welcome too, with a small rule:

• Like said above game must behave as original, any quality of life, fixes or modification should come optionally, maybe an ON/OFF toggle or like an optional mod, reason is some people would like to still play the vanilla game

Todo:

• Touch overlay for android
• ImGUI menu like dethrace
• 3DFX path for hardware rendering (sdl3gpu and opengl)
• Relax opengl requirement to opengl/es2.0 for low-end android devices
• Dreamcast port
• PSvita port
• PSP/PS2 port (expect struggle perf)
• 3DS port
• Big-endian support (devkitPPC/retro macs/linux)
• FreeBSD
• Haiku port (maybe)
