d_event_debug equivalent & modifications to dEvLib_callback_c (#2359) 
* WIP d_event_debug
* Implemented most functions close to matching
* Removed erroneous comment in d_com_inf_game.h
* Implemented getEventP in dEvDtBase_c
* Retyped dEvLib_callback_c function returns from BOOL to bool
* Implemented getHeader, getEventList, and setDbgData in dEvent_manager_c
* Moved relevant dEvDb_* classes from d_event.h to d_event_debug.h and changed to structs
* Extended JORFile mFilename character array from 8 to 256 characters
* Implemented combo boxes and update slider functionalities in JORMContext
* Named field_0xC of JORProperyEvent as id, based on use of field in d_event_debug.cpp
* Corrected debug event tables and created missing table
* Debug tables explicitly pasted in d_event_debug.cpp to circumvent ShiftJIS not properly encoding tables via #include directive

* Change return types for implemented virtual functions of actors that inherit from dEvLib_callback_c

* Add const modifier to several d_com_inf_game functions called in d_event_debug, and change respective fields in dEvDb_bit & reg_c to be const

* d_event_debug Equivalent
* Changed configure.py entry to equivalent instead of matching
* Preliminary documentation

* Remove debug tables from d_event.cpp

README.md

The Legend of Zelda: Twilight Princess
Build Status Code Progress DOL Progress RELs Progress Discord Badge

A work-in-progress decompilation of The Legend of Zelda: Twilight Princess (GCN USA).

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

More information about the project can be found here: https://zsrtp.link

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%.
  • 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/tp.git

  • Copy your game's disc image to orig/GZ2E01.

    • 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 GZ2E01 (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.
