Animal Crossing

A decompilation of Animal Crossing for the Nintendo GameCube.

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)

A decompilation of the original N64 version of the game is being worked on here.

Dependencies

Windows

On Windows, it's highly recommended to use native tooling. WSL or msys2 are not required.
When running under WSL, objdiff is unable to get filesystem notifications for automatic rebuilds.

Install Python and add it to %PATH%.
- Also available from the Windows Store.
Download ninja and add it to %PATH%.
- Quick install via pip: pip install ninja

macOS

Install ninja:
bash
```
brew install ninja
```

Install wine-crossover:

bash

brew install --cask --no-quarantine gcenx/wine/wine-crossover

After OS upgrades, if macOS complains about Wine Crossover.app being unverified, you can unquarantine it using:

bash

sudo xattr -rd com.apple.quarantine '/Applications/Wine Crossover.app'

Linux

Install ninja.
For non-x86(_64) platforms: Install wine from your package manager.
- For x86(_64), wibo, a minimal 32-bit Windows binary wrapper, will be automatically downloaded and used.

Building

Clone the repository:

bash

git clone --recursive https://github.com/Prakxo/ac-decomp.git

Update and Initialize submodules:
bash
```
git submodule update --init --recursive
```
Copy your game's disc image to orig/GAFE01_00.
- Supported formats: ISO (GCM), RVZ, WIA, WBFS, CISO, GCZ
Configure:
bash
```
python configure.py
```
To use a version other than GAFE01_00 (USA), specify it with --version.
Build:
bash
```
ninja
```

Diffing

Once the initial build succeeds, an objdiff.json should exist in the project root.

Download the latest release from encounter/objdiff. Under project settings, set Project directory. The configuration should be loaded automatically.

Select an object from the left sidebar to begin diffing. Changes to the project will rebuild automatically: changes to source files, headers, configure.py, splits.txt or symbols.txt.
