I have the same problem on my iPAQ. I have plenty of RAM (10MB) but most games don't work - I either get the black screen for a few seconds and then back to the MAMECE screen or the game doesn't work. The only one that I can get to work so far is Asteroids but it's running very slow.

I looked at iMAME but I don't like the interface for one and the games list is not very comprehensive - this emulator is the best if I could get it to work. It can't be bad ROMS because I've tried 10 or so from different sources. In some cases, I can get the title screen up but when trying to start the game it goes back to a self test. It's confusing.

Any suggestions?
