I finally decided to go swimming around in all the n64 sdk iso's I have lying around on my pc and lo' and behold, I finally found all the programs to create a fully working n64 sdk environment! This includes: The official MIPSE GCC used by Nintendo The N64 OS2.0L SDK The N64 OS2.0J SDK Manual (a more recently released user manual than the one you'll find online; I couldn't manage to find the OS2.0L manual though sadly) N64Kit developers tools Several things I need to point out The environment is partially Win16 based, so you'll need to be running on a 32-bit Windows operating system to use the sdk the nintendo and ultra folder should be placed on your C drive (C:\nintendo; C:\ultra) To use it, open up the command line, go to the /ultra folder, and run setup.bat. You'll find the demos in the usr/src/pr/demos folder and the manual in the usr/man folder. http://www.mediafire.com/?rpavmaxwczwz7e2 Source: http://www.glitchkill.proboards.com/index.cgi?board=ootmod&action=display&thread=5985
