THE WORLD’ S MOST EXPENSIVE CARTRIDGE
Nintendo created 90 special cartridges for use during the Championships. Each of these grey, numbered cartridges, contains four switches in top left corner that can be set to an on/off position in order to alter game parameters. These cartridges were given out to finalists after the competition was over. Nintendo also produced 26 gold competition cartridges, which were given out as prizes in a Nintendo Power magazine competition. A Gold cartridge sold on eBay for $100,000 in 2014, while the grey ones have sold for up to $18,000.
