Ok so I set up x360ce, everything was working fine except for the fact that only the 2 sticks and R2 would register when used in the configuration menu.In rocket league, it was very difficult for me to even select anything, as the buttons would just keep moving constantly. In free play, the car just boosted constantly and most of the buttons didn't work. I traded my X360 Controller for this PS3 controller from a friend, so maybe the controller is somewhat faulty? LED 1 doesn't light up either...
