Tried SM64 (2) which was done by YoshiParty back in the Day for the Wii. FPS is pretty good, you can not read Messages that come up, and there are some Graphic Issues, but it in the Playable area. So yes, seriously needs to be looked into, and we could have a pretty good N64 Emu. But also need to get it to run from the 3DS Home Screen. If I remember correctly, under HBL, it will not run fully, but if it is done from the Home Menu (Installed), it should have Access to the full System.
