Any reports on MAME, Final Burn Alpha or Turbografx?

My Dash and G1 (between the two) plays these fairly well (Turbografx on Dash is perfect).

I would expect the N900 to perform very well with these, since Pandora and PSP do. The games will not control as well or course, but they should play as good with full sound.

.... Why use the accelerometer? Apple device you have no choice, but the N900 has the keyboard (of course).
