I have brand new NES USB controllers, and when I plug them into my win 10 desktop the computer recognizes them and installs them, but FCEUX fails to recognize them. I go into Config > Input and click on a configure option for controller 1 such as "Left" but when I do anything on the controller FCEUX won't recognize it. The roms open up properly on FCEUX, does anyone know what needs to be done here?
