I'm really having trouble opening ROMs on gpsPhone. When I start the app, everything works fine, but when I select which ROM I want to play, it goes to the skin, freezes, and about 10 seconds later, it returns me to the home screen without any error messages or anything. The ROMs are .gba files, and I have the BIOS installed. The permissions in the gpsPhone.app folder are 755 and the ROMs are 777. HELP!
