How does the game know which controller is plugged >in so it can respond properly? It'd be pretty easy: just read from the paddle input. If there's no paddle there, the input will be higher than any possible case where there is a paddle. (open circuit, infinite resistance being higher than any resistance a paddle can provide.) That might not be how Astroblast does it, but it's how I'd do it. I believe Astroblast only checks at powerup, or maybe at game start. -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
