@retznutz I'm very interested in this! I have likewise wanted to make a cabinet version of intellivision controls. I thought about something like the stream deck (video buttons).

I was thinking of larger controls that fit the hands rather than the thumbs; one hand for the disc (3.5" disc?) and one hand for the buttons. How about the 5" screen, vertical, with the overlay 150% larger (four fingers across)? I had in mind the side buttons could be real buttons.

Staying tuned on this!

@Shizzmoney you don't need to copy it to add extensions. Just create a file /opt/retropie/configs/all/platforms.cfg with a line fds_exts=".nes .fds .zip" (with your extensions and update the emulator in question.

If we have a missing extension though it should be reported back to me :-)
