That's a fun peripheral. I've done papers on various video game add-ons and other forms of connectivity over the years. This one is one of my favorites. I've never played the game in question, but did sound interesting.Another similar peripheral that I liked researching was the PlayCable for the Intellivision. Cable Companies would stream a looping cycle of 8-10 games, switching out the games played each month. Each game was about 8k - 16k in size, so looping through 10 games didn't take long and you could eventually play what you wanted to if you waited long enough. Some kids found that having the PlayCable was like having a dev kit and ended up making the Bump & Jump port. (I think that's how that story went). PlayCable was decommissioned shortly afterwards so others wouldn't figure out that little trick.
