Ransom Posted February 23, 2010 Share Posted February 23, 2010 I'd found a site that had instructions on converting a Genesis controller so that a second button will work with the Colecovision. I recall it had to do with isolating the ground for the second button, adding a couple of resistors, and a little bit more. But somehow I lost my link to that page and I can't find it with Google. If anyone has a link or information on how to perform the mod, please post it! Quote Link to comment Share on other sites More sharing options...
