Okay, this is going to sound a bit outlandish, but I'll just throw it out there. I've been thinking of a way to access the dip switch menu in games when using these emulators and had one idea. Do you think it would be possible to use a save file to access these menus? The emulators don't allow you to do this, but the games do, so I was thinking, if you actually saved a game in the dip menu, then load it up on your PSP, it should work right?
The only problem I can think of would be save file format... Do MAME or Kawaks use a similar save file format as the emulators in question and if not, would it be possible to convert the save file into the right format?
