Mario Kart Double Dash!!

WIP 1:1 Decompilation of Mario Kart Double Dash!!

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

Currently only the debug version is supported.

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
  

• Install wine-crossover:

  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:

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:

  git clone https://github.com/doldecomp/mkdd.git
  

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

  • 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 MarioClub_us (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.

Credits

• SwareJonge for originally starting this project, and for guiding many people in their first contributions towards a decomp.
• Seeky for ppcdis, without it this project wouldn't have been where it is now.
• encounter for their amazing tools (decomp-toolkit, ObjDiff, et al.) which have so helped not only this project, but the entire decomp community.
