Jan Beta@mos_8502 Maybe the C64s analog paddle inputs could be used for the extra buttons (assuming this is about a C64 game)? At least that way you would not need an add-on (but still a slightly custom controller, obviously). SID registers though, not handled by the CIA but should still be relatively easy to do in software. No idea if that’s feasible, just a spontaneous thought. 🤔
BigPeteThis is pretty interesting! Though I wonder if 4 action buttons + start would be more useful than 3 + Start and Select. I wonder if it's a timing thing and that the two extra buttons aren't responsive enough for that. I guess I should look through the repo before spouting off. hahah
