I picked up a micro USB OTG cable with the sole intent on gaming with my PS3 controller. I connected the controller and it works fine for the most part. I can navigate the phone and do random stuff, but when its time to game it seems as if the button sets are a bit off. I'd like to be able to map the keys within the game (specifically vice city) but can for the life of me figure out how to do it. Is it possible? Also will the Moga controller be a expensive but easy fix?
