A work-in-progress decompilation of Mario Party 4.

This repository does **not** contain any game assets or assembly whatsoever. An existing copy of the game is required.

Supported versions:

- `GAMEID`: Rev 0 (USA)

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):
```
brew install ninja
```
- Install [wine-crossover](https://github.com/Gcenx/homebrew-wine):
```
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:
```
git clone https://github.com/Rainchus/mp4-dtk.git
```
- Using [Dolphin Emulator](https://dolphin-emu.org/), extract your game to `orig/GMPE01`.

- To save space, the only necessary files are the following. Any others can be deleted.
- `sys/main.dol`
- `files/rels/*.rel`
- Configure:
```
python configure.py
```
To use a version other than `GMPE01` (USA), specify it with `--version`.
- Build:
```
ninja
```

Visual Studio Code
==================

If desired, use the recommended Visual Studio Code settings by renaming the `.vscode.example` directory to `.vscode`.

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`.
