The Legend of Zelda: Skyward Sword
Build Status Progress DOL Progress RELs Progress Discord Badge

This repository contains a work-in-progress decompilation of The Legend of Zelda: Skyward Sword for the Nintendo Wii system.

This repository does NOT contain any game assets or assembly. An existing copy of the game is required in order to contribute.

Currently, the only supported version of the game is SOUE01: the NTSC-U 1.0 version (USA).

🔗 Dependencies

If the following steps don't work for you, please refer to the dtk dependencies documentation.

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%.
  • 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/zeldaret/ss.git
    
  • Using Dolphin Emulator, extract your SOUE01 game ISO to orig/SOUE01.
    • Right-click The Legend of Zelda: Skyward Sword game in Dolphin and select Properties to open a new window containing various game properties The Legend of Zelda: Skyward Sword is selected in the Dolphin Emulator. The "right-click" context menu has been opened and the "Properties" option is highlighted.
    • Select the Filesystem tab at the top of this new window (it should be the rightmost tab)
    • Right-click the entry labelled Data Partition and select Extract Entire Partition... The Legend of Zelda: Skyward Sword's properties window in Dolphin with the "Filesystem" tab open. The entry named "Data Partition" is selected and the "right-click" context menu has been opened with the "Extract Entire Partition..." option highlighted.
    • Extract the partition to orig/SOUE01
    • To save space, the only necessary files are the following. Any others can be deleted:
      • sys/main.dol
      • files/rels.arc
  • Run the configure script:
    python configure.py
    
  • Build the project with ninja:
    ninja
    

🔬 Diffing

Once the initial build succeeds, an objdiff.json should exist in the root of this project.

Download the latest release of the object diffing tool, objdiff, from encounter/objdiff.

Once objdiff is opened, set the Project directory by clicking on the Settings button near the Project heading.

The top-right of the "objdiff" program with the "Settings" button highlighted next to the "Project" heading.

The project settings window should have opened. At the top of this window, click the Select button next to the Project directory heading.

The top of the project settings window with the "Select" button highlighted next to the "Project directory" heading.

Select the root of this project and objdiff should now be fully setup. 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.
