All.log++ is the combined efforts of the Super Mario World Disassembly and Commentary project. Compiled here is the source code of Super Mario World, made by MikeyK, but with a large amount of routines clarified with labels, comments, and code explanations.
this isn’t from the leak, they took the rom, used debuggers to obtain the code (“disassembled” it), and it gives out this. As time goes on, comments and more than were added to it. This alone cannot be assembled into a ROM without major modifications.
I talked to the EFF about this a while ago and stated that fair use is likely, given the fact the purpose of this is for documentation purposes, it is transformative due to being informative of the inner workings of SMW, and is not monetized.
I even talked to Nintendo about this and they have no decision whether to accept this or forbid.
