Hi Rodrigo, thanks for getting back. Indeed I am using the latest driver: 360Controller 0.16. As for Lego Avengers (for example), I think it does have controller support. One time (just once, mind you) it read the xbox one controller without a problem, without the need for joystick mapper. Then never again. I have a couple drivers floating around and am wondering if there's some conflict going on. Is it that joystick mapper will be in conflict with a game that has xbox controller support? I've set the game up as if I were using a keyboard, assuming JM would send keystroke info to the game. There is some communication with the game, but not entirely. Is there a game I should use as a test? One that has been proven to work with JM on the Mac, in full screen mode? Thanks for the help. w.
