There is a game for Atari 5200 called 'Space Dungeon.' In order to play it properly, the original game needs two joystics inserted into a specially designed holder. One controls movements, the other controls your cannon.
So what I'm trying to figure out how to do here is, set up the right analog of player 1 to be the left analog of player 2 - *but only for that one game.* This kind of stuff is easy for arcade games - because every game gets it's own specific file. However for MESS/console stuff, you get one generic config for Atari 5200 called a5200.cfg.
Does anyone know if there's a way to somehow configure console games per game? Thanks in advance.
