So I've jailbroken my ipad 1 ios 5.1.1 and I have snes9x es plus and a lot of games on it is working. I downloaded psx4all and downloaded some roms on it. Problem is that everytime I try to play a psx game on it, gameplay is frozen except sounds. If I back out and go back into the app, the gameplay changes images. I've downloaded bios but don't know where to put it.
