Earthworm Jim - framerate seems good in demo, but can't get into game a giant 2d sprite blocks the screen on startup.
Excitebike 64 - freezes before main menu
F-Zero X - plays very well. Has the odd border around the game. Getting past the car setup can be hard because the buttons disappear for some reason.
Fighting Force 64 - freezes before main menu
Goldeneye - choppy. Some of the sprites that would normally appear onscreen before gameplay get in the way. Generally slow framerate.
Indiana Jones and the Infernal Machine - won't load. Black screen.
Jet Force Gemini - same stretched polygon glitches as Diddy Kong and Conker
Kirby 64 - plays, but the screen is multiplied (and Kirby has no face). The buttons stay in the same place, but the screen shows them somewhere else. Playable with practice probably.
Mario Kart - Slow framerate that gets choppy when there's more things on screen.
Mario Tennis - crashes. Won't load
Mickey's Speedway - Crashes before menu
Mischief Makers - Very choppy and graphics flash
NHL 99 - very choppy, but still almost playable. A lot of sprites block the screen while trying to start a game.
Nightmare Creatures - Slow, but not really choppy
Nuclear Strike - a little choppy, but playable
Paper Mario - lots of graphical glitches, but still playable
Perfect Dark - crashes before main menu
Pilotwings 64 - graphical glitches and slow. Still kind of playable.
Pokemon Snap - graphics work perfectly. Can't turn the camera (may just be me not knowing how to do things)
Quake - graphics glitches, flashing screen, unplayable.
Quake 2 - choppy with onscreen enemies, clipping problems, semi-playable.
RaMPAGE 2 - great
Rayman 2 - slow load and then, audio no video
Resident Evil 2 - super slow load, but eventually it gets to the main screen. The opening cinema has no audio. Crashes after opening cinema
Road Rage 64 - smooth, but a little slow. The background/sky blocks out part of the screen, so its definitely having a problem with 2d sprites, again, and probably hardware fogging.
Rush 2 - a little slow, but very playable
Shadowman - almost gets to the main screen and then just gets stuck with an image of the mask and the music playing
Space Station Silicon Valley - Some missing polygons, but playable and at good speeds, too.
Starfox 64 - plays really well. A little bit of choppiness, but very playable.
Star Wars: Rogue Squadron - won't load. Just get a black screen with the control overlay
Star Wars: Battle for Naboo - won't load. Black screen, no controls.
Super Mario 64 - nearly flawless. A little slowdown or choppiness, but very very playable.
Super Smash Bros - again it has the weird border, but runs very well with two characters onscreen.
Turok - half the screen is taken up by a sprite that shows your state and the controls aren't actually visible, but it runs smoothly
Turok 2 - the cinemas played pretty choppy and when it came to gameplay, the status sprites from part 1 take up the whole screen. Unplayable.
Turok 3 - Lots of clipping and slowdown. No persistent sprite blocking the screen, so its playable to some degree.
Vigilante 8 - the menus are a black screen mostly, but if you can get into the game, its there. Pretty slow and choppy though
WWF No Mercy - a little choppy in the sound FX, but the game was always a bit slow, so it seems full speed to me. Very playable.
Wave Race - same thing with the border. Plays at about 1/3 speed or less, depending on whos onscreen.
World is Not Enough - plays very very smooth for the little I played. No problems at all. Except, there doesn't appear to be any sound.
Worms Armageddon - Screen is a bunch of stretch images. Unplayable
Those are all the ones i've played. Hopefully, it will help someone.
