Several of Mitchell's high scores were disputed earlier this year by a forum poster claiming he used an emulator to record his scores, rather than a standard arcade cabinet.
Mitchell, featured in the documentary The King of Kong, has always been considered a master of the arcade, having once held world records in Pac-Man and, of course, Donkey Kong, for which he was thought to be the first player to gain one-million points. For that reason, Twin Galaxies requires that all valid high scores be achieved on original hardware, something it's no longer convinced Mitchell did after its investigation. "The use of MAME or any other emulation software for submission to these leader boards is strictly forbidden". Mitchell, however, is holding firm that his scores were legitimate, and he intends to prove it.
There's no denying that Mitchell is a ridiculously skilled video game player, his ideal Pac-Man score is a mind-boggling feat of memory, patience and pixel-perfect control, but, as this situation continues, the Floridian native risks this recent revelation becoming the defining mark for his entire gaming career.
"We also recognize records for First flawless score on Pac-Man and Highest score on Pac-Man". "Our investigation of the tape content ends with that conclusion and assertion". In 1999, he was recorded as the first gamer to notch a flawless score on Pac-Man.
The Donkey Kong champ - whose rivalry with Redmond, Wash. schoolteacher Steve Wiebe was documented in the 2007 release King of Kong: A Fistful of Quarters - is embroiled in scandal.
Over the weekend, Mitchell addressed the ruling in a video posted to YouTube. "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". "We will show that everything that has been done, everything was done professionally, according to the rules, according to the scoreboard, the integrity that was set up", Mitchell said.
