i am using winsp and have downloaded the gba roms and put them in the new file marked GBA in the same folder my NES roms are in. but when i open up the gpsphone ap on my itouch i get a message that reads" sorry, but ipsp requiras a gameboy adva.. you have an incorrect iso imag. I also went into the properties of the sonic.gba rom and changed the permisson to 0755? any ideas??
