GBA developer and reader ZoMBi146 has coded 3 different N64 emulators. Each one is designed specially for one of 3 games: 1 for Mario 64, 1 for Goldeneye, and 1 for Zelda: Ocarina of Time. He claims that these have been individually tweaked for sound controls and speed. It is said that these are all running at full speed! No word on release yet but I Hope It is soon!
