Contributing to RB3Enhanced

We welcome all contributions to help make RB3Enhanced a better mod, by improving existing features or adding new ones.

Codebase

Visual Studio Code config files are included in the repository, so if you are using VSCode as your IDE, make sure it is following this file.
For cross-platform compatibility reasons, the codebase aims to be C89 / ANSI C. Variables must be defined at the start of functions rather than inline.
- Wii-specific implementations (must be guarded by #ifdef RB3E_WII) may be compliant GNU C99.
- Xbox-specific implementations (must be guarded by #ifdef RB3E_XBOX) may be slightly non-compliant, as MSVC's C89 implementation is non-standard.
All indentations should be 4 spaces.
Try to adhere to any existing code styling already used in the codebase.
Function addresses should be added to include/ports.h in the respective platform section.
When adding a function reference (whether as a hook or as a callee), make sure to add a unique stub in source/_functions.c and definitions of the original function in a header file in include/rb3.
Please make sure all your contributions are able to be licensed under the GPLv2 or later. This means not using non-free or incompatibly licensed libraries or external code.

Test your changes before submitting them as a pull request, to ensure that they don't crash.
- Emulators may mask fault behaviour, or return different results compared to a real console, so it's advised to use real hardware if possible.
If applicable, try to include port addresses for both Xbox 360 and Wii in your contribution.
- If you can't do this, guard the implementation behind #ifdef RB3E_{PLATFORM}.
It's recommended that you enable "Allow contributors to edit code" in your pull request, so quick fixes can be added by us before merging.
Try to keep a clean Git history.
