Billy Mitchell, the former King of Kong, has been dethroned after his scores were scrubbed from Twin Galaxies' leaderboards in the wake of a dispute asserting that the high score record holder in games like Donkey Kong, Pac-Man, and Donkey Kong Jr., used an emulator and not the original arcade cabinets, which is strictly against the rules.
Mitchell first became famous for achieving a perfect score in Pac-Man in the 80s, before rising to prominence in the 2007 documentary, King of Kong, which focused on the rivalry between Mitchell and everyone's favourite underdog Steve Wiebe. The dispute arose when forum poster Jeremy “Xelnia” Young claimed that Mitchell had used MAME (Multiple Arcade Machine Emulator) and not an original arcade machine as the regulations for submitting a high score state.
