UPDATE: Not sure how it happened, but the keyboard was no longer "configured" in retropie. So I re-configured it as a controller... and now my keyboard is working for both the Atari2600 and 800. I am able to use the old school joysticks for gameplay, with the keyboard for the extra buttons. So to tweak my question... for those of you using older joysticks with limited buttons, what's your favorite way to handle those extra buttons for emulators that need it? Use the keyboard and label those weird buttons (like Option, difficulty, etc) so others can play without you babysitting? I saw someone solder buttons onto the atari joystick to handle those extra 2600 buttons - that seems aggressive! I was thinking of a small, wireless keypad (like this: https://www.amazon.com/Jelly-Comb-Financial-Accounting-Extensions/dp/B078XQR7R6/) that I can label to make it easy for others. Thoughts?
