With the amount of Nintendo characters appearing exclusively on a Nintendo system, it’s understandable why we tend to forget there was once a time when the company would release their games on other consoles. Nintendo originally got into the North American market by releasing their games on systems like the ColecoVision and the Atari 2600.
Speaking of Atari 2600, a Mario Bros. prototype cartridge has surfaced on eBay. The cart was tested and is confirmed to be real. The seller dunkindealz, has a feedback score of 3987 and has a 99.7% positive feedback score.
The current asking price for the prototype is $2,500.
