I have an issue. I bought Aladdin on the Genesis about two weeks ago from a guy on Ebay. When I tried playing it, the game froze once I started playing on level 1. I tried cleaning the game, and my console, but it always froze within 10 seconds of gameplay. Strange thing #1, the game wouldn't freeze if I just sat there and let Aladdin just do his idle animations. Nor did it freeze at any time on the menu screens.
Strange thing #2, I returned the game assuming it just didn't work, and I bought another copy. I just got it and tried playing it, and it does the exact same thing. My genesis plays every other game I own perfectly. It's only Aladdin that doesn't work. Why do two completely different cartridges freeze the same way? It doesn't make any sense to me, does anyone else understand this?
