Okay, so I downloaded USB Overdrive. I didn't buy it as I wanted to see if it works first. I created new settings and set the application for Nestopia. All the buttons register with USB Overdrive but when I try to play a game the controller still doesn't work. Anybody know what I can do to get it to work?
EDIT: I somewhat got it but only the start button works.
EDIT: Alright so I got the start button to work to start the game but after that it doesn't work and I got the up,down,right,left arrows to work on the gamepad in the menu of the game but not A & B and start and select in the menus of said game. I'm using a NES controller and the game is Tecmo Super Bowl. I feel I've done all I can to try to get it to work. If anybody knows anything I'm missing about USB Overdrive would be much appreciated.
