Here's a couple of things to consider:
- MameCE (MegaCE even more so) is S-L-O-W at loading... it still takes a minute or two on my overclocked iPaq 2215. Just give it a LOT of time and it'll probably load up.
- Both versions run VERY few games. You're pretty much limited to the classics (for instance, pretty much all I use it for is Donkey Kong and Space Invaders)
- Some of the games they claim to run don't work. I have the same black screen/exit issue with Ms. Pac-Man and a bunch of other roms. Just try different ones and see what works and what doesn't.
