I was reading the Ebay scam when I thought of the best scam from back when I was a kid.
I went a local Video Store and rented

Once I had the game I would open it up using a screwdriver and remove the Tecmo Super Bowl Rom.
I would then take Mario Brothers or Duck Hunt and open it up

Once they both were open I would swap out the games and BOOM I had Tecmo Super Bowl.
I did this with 5 or 6 games and the store never caught on!
