Contributing

Due to the overwhelming majority of the DOL being library code, we will not be accepting external contributions to the DOL. DOL contributors are expected not to use LLMs to assist with library decompilation in any form, including but not limited to bytematching or documentation. This is to ensure that information about the libraries is strictly sourced from user-obtainable releases. This includes:

• Big Brain Academy: Wii Degree (2007)'s debug linker maps
• Tokyo Friend Park II Ketteiban: Minna de Chousen! Taikan Attraction (2009)'s debug build + DWARF info
• Challenge Me: Word Puzzles (2011)'s debug object files + DWARF info (where applicable)

External contributions for the REL are acceptable. REL contributors may use LLMs to assist with matches and documentation. Because pull requests are disabled, it is recommended to fork the repository and ping one of the maintainers in the above Discord server.
