RGB-Pi OS AdvMame Mappings Problem

[galaga88]

Can't map either Keyboard or Joystick Buttons/Coin/Start in AdvMame. (only ESC('esc' key) and INSERT COIN ('9' Key) seems to work out of the box (nothings else can be added or edited) Editing /opt/retropie/configs/mame-advmame/advmame.rc doesn't help either.

Any Clue as to how configure AdvMame button mappings with RGB-Pi OS?

Thanks!

Disconnect your keyboard before launching advmame games. Otherwise the gamepad/joystick won't work properly
