Famous competitive gamer Billy Mitchell was one of the best arcade gamers of all time getting high scores in the likes of Pac-Man, Donkey Kong and more. The Guinness World Records organization quickly followed suit, but Mitchell isn't stepping down quietly.
It appears that he was actually playing the games on a Multiple Arcade Machine Emulator (MAME), which is against Twin Galaxy Rules, and a video of the record-breaking game of Donkey Kong shows transitions between levels which are not possible on an original arcade machine.
He made his statement to Old School Gamer Magazine and the video in question was uploaded by YouTube user Ryan Burger.
"The Guinness World Records titles relating to Mr. Mitchell's highest scores on Donkey Kong have all been disqualified due to Twin Galaxies being our source of verification for these achievements", a Guinness representative told the web site.
Billy Mitchell's Donkey Kong and Pac-Man records have been disqualified by Guinness World Records. Throughout Twin Galaxies' review process, Mitchell held his tongue even though he had the opportunity to defend himself. The dispute alleged that Mitchell achieved his scores on an emulator and not original hardware, which opens the door to cheating through a variety of methods.
"The fact of the matter is, now there's a true professional due diligence being done to investigate things that happened as far as 35 years ago", he said.
In a professional manner, not in a shock-jock mentality designed to create hits, we will show that everything that has been done - everything was done - professionally, according to the rules, according to the scoreboard, [and] the integrity that was set up. We'll see hopefully see if what he has is enough to prove his scores are legitimate soon, so stay tuned.
