Nearly 100 never-before-seen Nintendo cartridges found in Wisconsin game shop
Key Points:
- A Wisconsin game shop owner discovered nearly 100 previously unknown copies of Super Mario Bros. and Duck Hunt cartridges with unique screws, labels, motherboards, and manuals, differing from known versions.
- The cartridges, produced in 1993—two years after the last known copies—were found in storage after being purchased from a man who kept them untouched for 20 to 30 years.
- Despite the cartridges’ differences, the games play identically to the original Super Mario Bros. and Duck Hunt, which is one of the most documented and popular video games in history.
- Several cartridges received a perfect 10 grade from Professional Sports Authenticator, marking a first for Nintendo Entertainment System games, with some scheduled for auction at Goldin Auctions.
- Experts speculate the cartridges may have been manufactured as replacement stock for repairs or for a planned but unreleased bundle, making this discovery exceptionally rare and valuable.
