You can try interpreter for these.One thing I'm very impressed by is that the vast majority of what I've thrown at this emulator actually boots. Coming from the Wii U scene that's kind of amazing. I would be happy to contibute to a compatiblity list once the author deems it appropriate. One thing I've noticed and in relation to the aforesaid is both of the rom hacks Ive tried to boot will not. I have attempted Majora's Mask Master Quest v1.2 and Super Mario 64 Multiplayer v1.4 and both show a black screen while loading like all other games and then goes back to Retroarch ui with the message "Failed to load content". Small potatoes compared to the something like 40 games that I've booted and for the most part work well, but odd given both base games seem to work without issue.
