A work-in-progress decompilation of Animal Crossing.
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](https://github.com/zeldaret/af).

Dependencies
============
Windows
--------
On Windows, it's **highly recommended** to use native tooling. WSL or msys2 are **not** required.
When running under WSL, [objdiff](#diffing) is unable to get filesystem notifications for automatic rebuilds.
- Install [Python](https://www.python.org/downloads/) and add it to `%PATH%`.
- Also available from the [Windows Store](https://apps.microsoft.com/store/detail/python-311/9NRWMJP3717K).
- Download [ninja](https://github.com/ninja-build/ninja/releases) and add it to `%PATH%`.
- Quick install via pip: `pip install ninja`
macOS
------
- Install [ninja](https://github.com/ninja-build/ninja/wiki/Pre-built-Ninja-packages):
```sh
brew install ninja
```
- Install [wine-crossover](https://github.com/Gcenx/homebrew-wine):
```sh
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:
```sh
sudo xattr -rd com.apple.quarantine '/Applications/Wine Crossover.app'
```
Linux
------
- Install [ninja](https://github.com/ninja-build/ninja/wiki/Pre-built-Ninja-packages).
- For non-x86(_64) platforms: Install wine from your package manager.
- For x86(_64), [wibo](https://github.com/decompals/wibo), a minimal 32-bit Windows binary wrapper, will be automatically downloaded and used.
Building
========
- Clone the repository:
```sh
git clone --recursive https://github.com/Prakxo/ac-decomp.git
```
- Update and Initialize submodules:
```sh
git submodule update --init --recursive
```
- Copy your game's disc image to `orig/GAFE01_00`.
- Supported formats: ISO (GCM), RVZ, WIA, WBFS, CISO, NFS, GCZ, TGC
- After the initial build, the disc image can be deleted to save space.
- Configure:
```sh
python configure.py
```
To use a version other than `GAFE01_00` (USA), specify it with `--version`.
- Build:
```sh
ninja
```
Diffing
=======
Once the initial build succeeds, an `objdiff.json` should exist in the project root.
Download the latest release from [encounter/objdiff](https://github.com/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`.
