The decision came after a lengthy arbitration process determined that Mitchell used the Multiple Arcade Machine Emulator (MAME) to achieve some record scores that had been said to be performed on arcade machines, a violation of Twin Galaxies’ rules.
Guinness continued, “We also recognize records for First perfect score on Pac-Man and Highest score on Pac-Man. Twin Galaxies was the original source of verification for these record titles and in line with their decision to remove all of Mr. Mitchell’s records from their system, we have disqualified Mr. Mitchell as the holder of these two records. Guinness World Records will look to update and find the appropriate holder of these records in the next few days.”
Mitchell had supposedly achieved the first perfect score in Pac-Man on July 4, 1999, at Funspot Family Fun Center in Weirs Beach, New Hampshire. He was declared “Video Game Player of the Century” at the 1999 Tokyo Game Show later that year and presented an award by Namco founder Masaya Nakamura.
