Famed high-score gamer Billy Mitchell, best known for his leading role in “The King of Kong: A Fistful of Quarters” documentary, was officially stripped of his Donkey Kong and other video game high scores and banned from submitting scores to the world’s largest tracker of video game world records following a decision that he cheated, Twin Galaxies announced today.

“With this ruling, Twin Galaxies can no longer recognize Billy Mitchell as the first million point ‘Donkey Kong’ record holder,” the group wrote in its announcement. “According to our findings, Steve Wiebe would be the official 1st million point record holder.”

Variety has reached out to Mitchell and Wiebe for comment and Guinness to see if his record there will stand.

The decision comes after months of research by the administrators of Twin Galaxies, which tracks world gaming records and helps the Guinness Book of World Records validate gaming scores, according to a statement released by the group Thursday morning.

The group writes in a statement released Thursday that Mitchell’s famous Donkey Kong score of 1,047,200 was not achieved on an arcade machine — a requirement for Twin Galaxies and Guinness — but rather through the use of emulation software.

“The rules for submitting scores for the original arcade ‘Donkey Kong’ competitive leaderboards requires the use of original arcade hardware only,” according to the group. “The use of MAME or any other emulation software for submission to these leaderboards is strictly forbidden.”

In investigating the allegations against Mitchell, first brought up when Jeremy Young filed a dispute in February, the group “meticulously tested and investigated the dispute case assertions as well as a number of relevant contingent factors.” They also say that at least two different third parties conducted their own explorations and came to identical conclusions. “Additionally,” according to the statement, “during the evidence gathering period of this dispute, numerous experts, hobbyists, and casual observers participated and contributed to this investigation.

“Based on the complete body of evidence presented in this official dispute thread, Twin Galaxies administrative staff has unanimously decided to remove all of Billy Mitchell’s’ scores as well as ban him from participating in our competitive leaderboards,” the group wrote. “We have notified Guinness World Records of our decision.”

Mitchell first came to a broader sort of fame when he appeared as one of the central figures in the 2007 documentary “The King of Kong: A Fistful of Quarters.” In the film, which was directed by Seth Gordon, Wiebe attempts to wrest the world high score for the Donkey Kong arcade game from Mitchell, who comes across as the bad guy.
