Hahaha, we got this game for free because I bought it with Yoshi's Island used from Ebgames. However, Yoshi's Island didn't work so I took it back and they gave me a refund for both games because they couldn't give a refund for just one game (since it came with a buy one get one free deal). Sweet!
Unfortunately, like most older games, this was only the cartridge. So imagine my surprise when I found all the rest of the stuff (box, instruction manual, etc.) at the Bainbridge Island Rotary Auction! They had a whole bunch of misc. video game manuals and boxes in a bag for a buck. What a deal! This makes this a complete set!
