Ooops nevermind! I figured it out, you need to reinstall the emulator after, I forgot that step!

I was trying to map 0 and 1 to the l2 and r2 bumpers.

I added these lines to /opt/retropie/configs/videopac/retroarch.cfg above the inclue:

input_player1_l2 = "num0"
input_player1_r2 = "num1"

and tried going into the emulator's "Quick Menu / Controls" by pressing Start + X

lr-o2em Controls Menu

and no luck.

There is just no option for anything other than direction and fire. the retroarch.cfg changes I can see in the menu, but don't actually work to select a game

Thank you! I will give it a try.

I'll leave the astrocade to you ;)

Done and done. GitHub isn't nearly as scary as I had imagined. I hope to work my way up to a script module submission when I have some time to learn a bit more. For now, I made some small revisions to my previous Astrocade artwork to make everything read a bit more cleanly.
