Some time ago, the high scores for Donkey Kong and Pac-Man from Billy Mitchell, the subject of The King of Kong documentary, were removed from the Twin Galaxies website. The scores were removed due to Twin Galaxies finding evidence they believed pointed to the scores being illegitimate due to cheating.
Ever since the scores were removed, Mitchell claimed he never cheated, and the scores were legitimate. Mitchell is taking this so seriously that he's actively suing Twin Galaxies, but there's more to it than just the accusations of cheating.
Mitchell's lawsuit involves going after Twin Galaxies for defamation of character for their public statement claiming Mitchell achieved the high scores via emulation. Mitchell's team claims that the appropriate fact-checking of his scores was not done, and that the story was pushed out to generate clicks and headlines. Obviously Twin Galaxies disagrees, and they say they've got the evidence to back it up.
This battle will indeed head to court, with the beginnings of the proceeding set to take place on July 6th, 2020.
