This was interesting, but actually trying to contribute to decomp.me was still really hard! I found a lot of code that seemed perfect except for instructions slightly out of order, or dead pop statements after the logical end of the function. I wasn't able to actually fix anything :(
Also, I wish there were a guide about how to start from nothing on a new GC game. That's more interesting to me than putting the finishing polish on a decomp project that already "works" functionally.
There will deffo be a lesson on how to setup a decomp project from scratch! This is far from finished, there's opportunity to add so much more. I'd argue that I'd rather teach the user the basics of matching first before diving into setting a project, as setting up the splits.txt or symbols.txt might be quite a leap for a beginner. Feel free to keep checking in once a week and the lesson will appear :)
I've honestly think "beginner" is the wrong target anyway. If you're interested in contributing to a decomp, assembly basics are table stakes. Focus on the things that someone who already knows assembly won't just know.
