This game is awesome! I tested it on original hardware using a harmony cart and it works great. The only issue I have noticed is that if you end with a highscore in the 10,000s it it chops off the 1 on the highscore in the subsequent games. (ie if you get a 15,520 your high score will show up as 5,520). I have been playing this a lot over the last 2 days and there are some combos of moves that I know are possible but that I almost always fail on. I'll get them!
