I know it's not stated anywhere that it works with this emulator, just checking to see there was a possibility. Running MP3 with the 1+2+3 version of the patched file, I can get all the way in game but it always crashes on mini game load regardless of what game it comes from. Did a bit of research and it seems like M64Plus Fz always has the expansion pack enabled (I did end up finding a tick box in which I could turn it off) but otherwise that's all the info I got.
Thanks a bunch, appreciate ya time.
