A Nintendo 64 emulator for Windows. Produced by a staff known by the pseudonyms Lemmy, hWnd, Atreides, LaC and EmuManiac. Found in <http://www.nemu.com/>.

Zophar's Domain calls this the currently most compatible emulator in existence; All I know from brief testing is that Yes, It Actually Seems To Work. (Not too fast on a PIII-600MHz, but playable anyway... =)

Nemu 64 uses DirectX interfaces (works with most 3D graphics hardware). Graphics rendering has several options (even a "perfect" rendering mode thats' probably pretty slow, but looks "as intended".) Sounds also work pretty well (Some games need "prebuffered" sound for some reason).
