Everything, except the display.
What does not
The display is broken; I can only see part of the piano, and everything else doesn't show and just randomly flashes sometimes. All text overlays seems to show though. I tested on a MacBookPro5,3 with NVIDIA GeForce 9600M GT; maybe it'll work better on some other graphics device?
What was not tested
I think I tested about everything
I also tried in Wine 1.7 (the one that comes with WineBottler) but the display is just black. So it's no good for it's intended purpose of learning piano (or whatever you'd need the display for) but still works fine as a MIDI player.
