Actually I don't think so. They have been very careful not to include any copyrighted material in the repository. For example, all game assets are not included. I believe the decompiled code itself can not be copyright protected by nintendo since the decompilation is written from "scratch"... Although I am not fully sure how the law are in regards to that.

I really, really doubt it's legal, or if it is not in a way that would be easily defendable in court. Disassembled code is not a clean room implementation, which is what's needed to reimplement e.g. GNU licensed code legally.

Even if it is from "scratch", it is still a copy. Which is then protected by copyright. Same way music covers are still protected by copyright even if I perform it myself.

Ok, you are probably right! I just seemed to recall hearing that if you write a code from scratch, that then “happens” to compile exactly into the same binary, then it is a bit of a “gray area” as to if the original owner has copyright or not.

Again, I honestly don’t know for sure, sorry for the confusion.
