Hello. I'm new here, and looking for info.
I received a gameboy game on eBay in a lot that had other games & 2 gameboys, and it says Super Mario 4 on it. Nothing else.
Googled it and found a wiki about it, but it honestly wasn't much help.
What I want to know is how common this is, if it's worth trying to sell online or take in to Book Off.
