This is more of a question specific to Stella v3.6.1, but I thought someone might have some good advice. I'm trying to play some Atari 2600 games that require the "keyboard" or "kid's controller". By default Stella has many of these controller input commands mapped to keyboard buttons, but the problem is two-fold: The default buttons mapped by Stella are randomly strewn across my arcade buttons (my setup caters to MAME buttons).I can't simply map the controller keyboard buttons (picture a telephone dial pad: 1-9,*,0,#) to my current controller setup because each game uses the controller differently. For example, in Big Bird's Egg Catch it uses 5 and 6 to move left and right. Another game Alpha Beam With Ernie uses 4 and 6 for left and right.Photos of original controller: https://duckduckgo.com/?q=atari+2600+kid%27s+controller&t=ffnt&iax=1&ia=images I first looked at Xpadder to solve the per game issue, but as far as I can tell Xpadder is only useful for gamepads, not keyboards. I don't think Stella itself supports per game controller configurations (or am I missing this?). Any thoughts?
