EDIT: Okay, I realize after reading the things I was supposed to read that I was dumb. Just don’t get RA from emu4ios. Got it. Too bad for me, though. I guess I’ll have to buy something like an iPad or Android tablet to get the real RA working well and stuff.
Non-jailbroken iPhones/iPads are not officially supported and “emu4ios” is NOT associated with us. If their builds are having problems you should talk to them.
You’ll either need to be able to compile and sign code yourself or jailbreak your device to use RetroArch.
