I have currently a tankstick setup for player 1 and player 2..now I have the Retro usb adapters and two NES controller. I saw in the setup there is a option for controller 1,2,3,4. I mapped the NES controllers to controllers 3,4 thinking maybe it would work as additional controllers. However this was not the case it must be intended for the few 4 player games out there. Is it possible to keep the mapping on both my tank stick and these 2 nes controllers??
