thanks for all the info but now that i know what it is i probably won't sell it. i've always wanted to dump it but never had anything to do it

It plays fine not a very good game
Could anyone give me a price? a friend offered me $20.

Hi, I've had this game for years now can't remember where i got it. Was wondering if any one knows anything about it. I've googled the name of it and can only find the normal sized cart. Any information would be great. Thanks (Mario just there to show size diffrence) http://i.imgur.com/7cXNn.jpg
