is it an old controller? i dont know if thats the case but i used to have the same problem the one i used to have was broken ps3 controller i think it fell on the floor so many times messed up i tried playing COD with this on ps3 but every time i press one button it pressed the other even when i tried using it on dolphin so i think you should change your controller if you can but that's just me
