Controllers for All cydia tweak brings PS3 controller support for a ton of games, no configuration needed!
Apple added a great game controller API in iOS 7 that a lot of game developers are taking advantage of, but the MFi controllers are extremely expensive! Controllers for All addresses that issue by starting with support for PS3 controllers, and will add more controllers support down the road.
Controllers for All already supports every game that’s been update with iOS 7 controller support in mind, and does it with an extremely simple setup, one time pair using your computer and you’re done! No other configurations ever needed again!
