Mario Kart is one of the most beloved series in the Mario franchise. It’s only fitting that Nintendo fans are willing to throw some serious money on collectibles for their favorite franchises. If you are one of those people and are a Mario fan, you’ll definitely want to see this.
A eBay seller who goes by steem69 is selling a prototype/tech demo of Mario Kart XXL on Gameboy Advance. The prototype is on a 3rd party PCB and the owner attempted to dump it online, but for some reason wouldn’t work. He has also posted a video of him putting the game in on GameCube and playing it.
Steem69 is currently asking $600, but has noted that he will also take the best offer.
