Hmm, not sure how you found that, but I can never seem to find an N64 emulator that works properly, or any 3D console for that matter. The 8 bit/16 bit stuff usually works like a charm though, and those consoles tend to have superior games anyways.
But anyway here's what I'd reccomend:
Mario 64
Goldeneye
Perfect Dark
Conker's Bad Fur Day
Mario Party
Jet Force Jemini
Banjo Kazooie
Wave Race
Kirby 64: The Crystal Shards
Donkey Kong 64
Diddy Kong Racing
Mario Tennis
NFL Blitz 2000
Pilot Wings 64
Basically check almost anything by Rare and you can't go wrong, they were freakin money on that console.
