He said he targets n3DS, so, if it runs stable on n3DS is actually fine. Maybe optimizing the emu for some other games could impact SM64 , but I think not even dev has an answer to your question right now.I know you said above that you don't target old 3ds for your projects, but do you think after you further optimize the emulator, that mario 64 will become at least playable on on o3ds?
