This is significantly harder to get working on other games than I thought. The instructions say you need an ELF file for the metadata but I can't find anywhere how you're actually supposed to get that from the game. Tried asking on some decomp servers but they're all more focused on decomp, naturally. I wanna learn how to do this stuff but man, there really are very little resources out there... It feels like something you just kind of have to know.
I did find a way to convert a z64 file to an ELF but I'm unsure if that's what I actually need to do. Gotta just fiddle with it myself I guess.
