Does anyone know of any examples out there of actual source code (used in released sold titles, not homebrew or reverse engineered code or the like) for any NES, SNES or Nintendo 64 game titles? Or any official used-for-commercial-development stuff for the 64 that is out there? (SDKs, libraries etc)
Off of the top of my head: Some versions of the official Nintendo SDK have been leaked, as have some third party ones (CodeWarrior(?), PsyQ). As for source code, iirc the "Acclaim project" torrents have some engine source code, don't know how much of that, if any, made it into released games though.
This guy has done awesome work to provide assembly coded N64 roms. This roms are actually used as unit test for cen64 emulator.
