I have an iPaq 3630 and version 9.10 of MameCE3. I'm having some problems with the roms I've downloaded. I can't get Galaxian or Glalaga to work at all (screen goes black for a few seconds, then goes back to the main screen), with Ghosts and Goblins, I can't run and jump at the same time and with TerraCresta, I get a Fatal Application Error. At the moment, I have close to 20MB free, so I don't think that's the problem. Can anyone help?
