Ok, my turn.

Working - no sound:
GTA 1 - well, at 850 mhz it works beautifully, I mean, Superspeed!
Metal Gear Solid - wont start the game, screen freezes.
Rollcage stage 2 - works on 2 maps only. Dunno why.
Star Wars Episode 1 - Jedi Power Battles (lol) works slow.
Gran Turismo - works perfectly
NFS 3 Hot Pursuit - works perfect.
VRally - works not bad, a bit slow despite 35 fps.
Destruction Derby - works perfect
Legasy of Kain - Soul Reaver - works not bad, a bit slow, but playable
