Hi, I'm new here and I just had a question. I bought a black and red Retro Duo on eBay, brand new and the guy has great feedback. Anyway, I got it and I just bought NBA Jam Tournament Edition (used of course) on ebay as well, so it's the only game I have so far. I put it in and it works fine, but I tried to take the game out and I had to try three times to get it out, I was pulling so hard and it wouldn't budge, finally I did get it out. So I put it back in to see if it still works and it does, but it's still just as hard to get out. Wiggling the cart around doesn't help get it out at all. I'm not sure what to do, whether it's the cartridge or the system. I don't have any NES carts to test yet either. The cart and system look fine, I don't know what the deal is. I could just keep it and keep jerking it out every time I want to play a game but that's dumb and it will break eventually. Anyone have a problem like that?
