Atari 2600 difficulty toggles on GPIO?
I've been looking all around without really finding anything. I am converting an old Atari 2600 into a Recalbox and I'm trying to figure out how I would get the A<->B difficulty switches to work hooked to the GPIO. I could probably write something custom but I was hoping someone had already solved the issue.
As far as i remember, no one ever did that. Eeven if you wire it through gpio, the emulator must handle the switch, i'm really unsure about that. And even if the emulator handles it, you must find a way to map it. If it's a core option, i'm afraid you won't be able to do what you wish
