i tried to play pokemon on my newly jailbroken ipod touch 4.2.1 but the error message of "sorry, but gpSP requires a Gameboy Adva image to run correctly. Make sure to go authentic one, it'll be exactly 16384 b and should have the following..." i downloaded the gba bios and gpsphone directly on to my ipod. do i have to connect it to a computer to change the file settings to make it work?
