this is kinda crazy. I was able to build the decomp, which outputs a json file to use with objdiff, but what to do then - no idea. I didn't try the n64 version. I think the gamecube version is supposed to be for porting the game to other systems as there are other systems outlined in the various sections. objdiff was somewhat buggy with updating automatically as well. it failed at first, then succeeded, but never reopened (not sure if it's supposed to).
