I could really need both turbo A and B buttons in a nes game, like “contra”,“shadow of the ninja” etc. so , I wonder how to config the “X” button as “turbo A” and “Y” button as “turbo B”.
BTW, I used to remap the"A" button to “X”, and “B” button to “A”, so that when I can press both A and B easily.
Any advices are greatly appreciated.
