(To those who are having stability problems, try using a real BIOS instead of the emulated one)
Tried it with Final Fantasy 7, and it worked great on a G3/800 iBook. FMV was nearly smooth (a hiccup every 30 seconds or so - looks like a caching algorithm needs some optimization), but in battles it slowed down tremendously to about quarter speed, if that. Here's hoping this can be optimized, as the old CVGS ran perfectly on a G3/233 back in the day.
Final Fantasy 9, always a troublesome game for emulators, did not work. Garbled screen, one note of music, and it crashed.
Super Puzzle Fighter 2 Turbo ran perfectly, except for the lack of game music (according to the read me, CD sound isn't ready just yet).
Need for Speed 3 ran just under half-speed. Very strange experience.
Interface looks great for a first release (Flarestorm is nice, but by and large Japanese programs have horrible, horrible interfaces). Here's hoping the performance improves, because so far it looks great!
