An NES prototype of Punch-Out!! pre-Mike Tyson dumped online, bought for $45,000, free to all
style="user-select: auto;">The video game preservation community has just experienced one of its happiest moments of the year. An anonymous buyer paid$45,000at Heritage Auctions to acquire a NES prototype from Punch-Out!!, a release before Mike Tyson's signing with Nintendo. And instead of putting it in a display case, he did something extraordinary: he dumped the ROM online via The Cutting Room Floor, available for free to anyone.
🥊 An "impossible" prototype
The cartridge would have belonged to a former Nintendo of America employee, sold at a garage sale. What makes it exceptional is its nature: Nintendo is notoriously secretive about its development process, and first-party prototypes of the NES are extremely rare. Frank Cifaldi, founder of the Video Game History Foundation, analyzed the video content with strong words:
"Usually, data on pre-production NES cartridges looks much like the final game. Not only is such an early look at NES development rare, but the fact that hile this being a first-party Nintendo game is unheard of. I've managed and studied NES prototypes for over 25 years, I've never seen anything like it, either physically or digitally."
🎮 What the prototype contains
The build is clearly under development, and very different from the final game we know:
- No sound,no music, no sound effects, audio code doesn't exist yet
- Only 4 boxers: Glass Joe, Bald Bull, King Hippo, Don Flamenco, in that order, in loop
- Piston Hurricane (from arcade 1983) in place of Piston Honda
- Pizza Pastain the intro list, a character totally absent from the final game
- Vodka Drunkenski, the original real name of Soda Popinski, taken from Super Punch-Out!! arcade
- Mysterious characters in credits: Rockyhead and Mongol Khan, identity unknown
- Zero mention of Mike Tyson, contract was not signed yet
- Approximate English interface and texts, color palettes different from final product
💾 ROM is available now
The anonymous buyer has authorized the full dump to be released. The ROM is accessible here: Mike Tyson's Punch-Out!! and on The Cutting Room Floor, which also documents in detail all the differences from the final game. Frank Cifaldi’s analysis video for the VGHF is available on YouTube. style="user-select: auto;">This is exactly the kind of act that advances video game preservation, someone pays a lot for a rare artifact, and instead of guarding it jealously, makes it accessible to history.
