• src/ – Decompiled C/C++ sources
• include/ – Reconstructed headers
• config/ – Project configs, splits, and symbols
• tools/ – Helper scripts and utilities
• docs/ – Documentation and notes

Legal Notices

This project does not contain game assets or proprietary data. It is a reverse engineering effort for educational and archival purposes.

An existing copy of the game is required.

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:

  brew install ninja

wibo, a minimal 32-bit Windows binary wrapper, will be automatically downloaded and used.

Linux

• Install ninja.

wibo, a minimal 32-bit Windows binary wrapper, will be automatically downloaded and used.

Building

• Clone the repository:

  git clone --recurse-submodules https://github.com/TeamOrre/xd-decomp.git

• Copy your game's disc image to orig/GXXE01.

  • 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:

  python configure.py

  To use a version other than GXXE01 (USA), specify it with --version.

• Build:

  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.
