Hi!
I built arcade cabinet and hit a brick wall when configuring joystick and buttons…
Is there a way to bind keyboard keys to buttons?
I have DragonRise Inc Generic usb joystick controllers, mapped all needed standard buttons in retroarch, but here’s the problem:
I’d like to use separate button for ‘insert coin’ and in retropie’s mame it’s ‘6’ by default. – so i’d like to map map extra ‘coin button’ to 6.
I also love pinball dreams on amiga (which uses both shifts) so i’d like to map additional side buttons as ‘shift’ and ‘rshift’
and i don’t know how to do that… 
I digged in this forum, search youtube and uncle google but i didn’t find the answer. Can You help my, my friends?
