Time to pull out the NES and Atari games out of that box in your attic. A Nintendo World Championships cartridge for the Nintendo Entertainment System was sold on Ebay this week for $99,902.00. The cartridge, one of only 116 ever manufactured, was made for an event in 1990 that ran across 29 cities in the US and was given away to competition finalists. 

The competition was based around scoring the highest in Super Mario Bros., Rad Racer and Tetris within a time limit of 6 minutes and 21 seconds. The three games were put on the game cartridges that were designed for the contest.

Other Nintendo World Championship cartridges have been auctioned in the past, many of which sold for tens of thousands of dollars.
