I spent considerable time trying to find the answer to this question(s): How do I properly map my control panel to Retropie, and why can't i use it as a two player controller?
I build a two player counsel (x-arcade style) control panel for a Raspberry Pie #3 running Retropie. The panel has 6 buttons per player, and two "start buttons" = 14 buttons and two joy sticks (Happ Ultimates).
The buttons are functioning and appear to be wired correctly. I programmed a PS3 controller and this is controller is functional within my Roms.
I have looked on Youtube, google, and the forum - But I can't find what i am looking for. Can anyone help me? Perhaps my terminology is creating some challenges in my search for info...
Thanks as always.
