I picked up a complete copy of Joe and Mac 2 for the SNES about a week ago. It's complete in box.
This is somewhat of a rare game, and the value is really starting to climb, so I decided to get it now before the price gets any crazier.
I had played the original Joe and Mac as a kid, and I really enjoyed the two-player mode, so I decided to pick my own copy last year. I felt that I might as well get the sequel too while I was at it (it also has a two-player mode).
