This repository contains a work-in-progress decompilation of Radio Helicopter, also known as MiniCopter: Adventure Flight in the Americas, and プチコプターWii アドベンチャーフライト (Puchi Copter Wii: Adventure Flight) in Japan.

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

Supported versions:

• RGCPGT (EUR)

We recommend joining our Discord server for discussing the game, as well as for getting help if needed.

• GC/Wii Decompilation Discord: Contains usefult resources for Wii decompilation.

• Wii Sports, Xenoblade Chronicles and Kirby's Epic Yarn decompilation projects contributors: For the library code and headers.

• decomp-toolkit contributors: For the template used to create this project.

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

• 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'

• 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.

• Clone the repository:

  git clone https://github.com/my/repo.git

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

  • 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 RGCPGT (EUR), specify it with --version.

• Build:

  ninja

  The final main.dol file will be located in build/[VERSION]/

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.
