I have installed GBA Emulator on my iPod Touch. I now have managed to install Pokemon Emerald onto it. Now I press start new game, and I get a screen with a black background, and grey GBA buttons on the screen. How do I know play the game? I have tried tapping some of the buttons, but the words at the top of the screen say "You have an incorrect IOS Image", or something like that. Then the iPod just returns to the home screen. What do I do to play it? Any help muchly appreciated.
