ok so for .cfg files, is there a way to have it set so i when i want to play NES,snes,gen, etc that i can plug in my snes usb controller and play that way, and then when i want to play psx gaes i can plug in my ps3/360 wired controller and play those games with those seperate controls? because i got the ps3 controller setup easily, but then i wanted to go back to the snes controller and i had to delete a bunch of buttons and run the retroarch config again, which is a hassle.
