If that's true then how'd they put up Super Mario RPG. Oh wait, they haven't.
* Luigison goes to check wiki for SFX games.
Edit: Hmm. I was thinkg that SMRPG used the Super FX chip because it didn't work in my Tristar 64. I was thinking it had extra connectors on the card, but now I'm not sure since it wasn't listed on Wiki.
Edit 2: Ah, it's the Super Accelerator 1 chip that's on SMRPG
Looking at this list it seems possible that emulation could be what's holding up some games like SMK, Pilotwings, SMRPG, SF, and YI.
