A native PC port of Animal Crossing (GameCube) built on top of the ac-decomp decompilation project.
The game's original C code runs natively on x86, with a custom translation layer replacing the GameCube's GX graphics API with OpenGL 3.3.
This repository does not contain any game assets or assembly whatsoever. An existing copy of the game is required.
Supported versions: GAFE01_00: Rev 0 (USA)
- MSYS2 (https://www.msys2.org/)
- Animal Crossing (USA) disc image (ISO, GCM, or CISO format)
Open MSYS2 MINGW32 from your Start menu and install:
pacman -S mingw-w64-i686-gcc mingw-w64-i686-cmake mingw-w64-i686-SDL2-
Clone the repository:
git clone https://github.com/flyngmt/ACGC-PC-Port.git cd ac-decomp -
Build (from MSYS2 MINGW32 shell):
./build_pc.sh
-
Place your disc image in the
rom/folder:pc/build32/bin/rom/YourGame.ciso -
Run:
pc/build32/bin/AnimalCrossing.exe
The game reads all assets directly from the disc image at startup. No extraction or preprocessing step is needed.
Keyboard bindings are customizable via pc/build32/bin/keybindings.ini.
| Key | Action |
|---|---|
| WASD | Move (left stick) |
| Arrow Keys | Camera (C-stick) |
| Space | A button |
| Left Shift | B button |
| Enter | Start |
| X | X button |
| Y | Y button |
| Q / E | L / R triggers |
| Z | Z trigger |
| I / J / K / L | D-pad (up/left/down/right) |
SDL2 game controllers are supported with automatic hotplug detection. Button mapping follows the standard GameCube layout.
| Flag | Description |
|---|---|
--verbose |
Enable diagnostic logging |
--no-framelimit |
Disable frame limiter (unlocked FPS) |
--model-viewer [index] |

Graphics settings are stored in pc/build32/bin/settings.ini and can be edited manually or through the in-game options menu:
- Resolution (up to 4K)
- Fullscreen toggle
- VSync
- MSAA (anti-aliasing)
- Texture Loading/Caching (No need to enable if you aren't using a texture pack)
Custom textures can be placed in pc/build32/bin/texture_pack/. Dolphin-compatible format (XXHash64, DDS).
Save files are stored in pc/build32/bin/save/ using the standard GCI format, compatible with Dolphin emulator saves. Place a Dolphin GCI export in the save directory to import an existing save.
This project would not be possible without the work of the ACreTeam decompilation team. Their complete C decompilation of Animal Crossing is the foundation this port is built on.
AI tools such as Claude were used in this project (PC port code only).
