According to the physicist Albert Einstein, the most important thing is not to stop questioning. So, when I saw the news about a Super Mario Bros. cartridge sold over $100,000, I first wondered if the Retrogaming Community has gone crazy, and start reading a bunch of articles about the multiple variants of the most iconic game released on Famicom / NES around the World.

Differences are mostly found in localization, labels or number of screws in the back of the cartridge, but the hardest part during my research was to find a website listing all of those variations.

After hundreds of eBay and Yahoo Japan auctions visited… I decided to create it.

Happy 35th Birthday Little Big Mustache!
