Is there a way to have multiple player 1 controllers, like the way mednafen lets you assign controls? for example the way mednafen puts the number in parenthesis - input 1 UP (1) UP(2), where (2) is the second controller you want to use to send UP to player 1. That way you can use either an xbox360 controller, or a genuine system controller if you feel like it and you don’t have to remap controls when you want to switch.
Nope, not currently. But if you use autoconf you can just plug the controller you want to use.
