Hi!
I'm using the usb guns that came with my Arcade Guys cabinet ... I am able to get the cursor to move around, but I can't get the guns to actually fire -- is the mapping done within the recalbox controller config, or within tetrarch settings?
EDIT: In the Retroarch settings, I am not able to map gun start or gun select to any of the gun buttons, it shows "mouse 1" next to gun start ....?
