Nintendo Player has just obtained an historic Mario prototype for the NES. While I’m still checking the game for changes, I can say for sure that in its current state the game is nearly unplayable.

Nintendo has a strict policy when it comes to its prototypes. For that reason, few true betas from the Mario series exist outside of Nintendo’s headquarters.

This cartridge is, to my knowledge, the only copy in private hands and has never been seen by the general public before. Again, and I cannot stress this enough, my Mario NES prototype is nothing if not historical.

Please try to stay patient with me while I continue to search through the game code and prep the article. Check back early next month, when all will be revealed.
