Adding an additional button to an already configured Gamepad
-
Hello! I have a rare question, but Im hoping someone can help. I have an arcade with 4 joys/buttons set up as Gamepads 1-4 in Emulation Station. One of the buttons is a specific "Coin" button, that I have mapped as "Select" and it is also my "Hotkey."
I also happen to have 4 actual coin buttons (the ones that say 25 cents) that I want to make the only "Coin" buttons.
My question is, can I just add a line of code to the .cfg file in opt/retropie/configs/all/retroarch-joypads...for example: input_r3_btn = "12" and wire the actual coin buttons to each individual usb decoder and plug it into the #12 slot? Then go into the emulator and set R3 as "Coin"?
I want to avoid having to remap each gamepad, so Im hoping this will work! Thanks for your time!
