OK, I'll report my findings on SM64 -

• Title - ~30fps
• Mario's Head - ~7fps
• Save select - ~35fps
• Peach's Letter - ~20fps
• Camera panning cutscene - ~15fps
• Outside the castle - ~17fps
• Inside the castle - ~15fps
• In Bob-Omb Battlefield - ~10fps

So, in other words, playable, but not in any way ideal. But I've found a few noticeable bugs -

• Lakitu has no eyes
• No star on doorway
• No Peach portrait on castle
• Missing flags on camera panning cutscene
• No water
• Coins are invisible

But, obviously, I don't expect this, as a first release, to be perfect.
