Over the years, King of Kong star Billy Mitchell has seen his world-record Donkey Kong scores stripped, partially reinstated, and endlessly litigated, both in actual court and the court of public opinion. Through it all, Mitchell has insisted that every one of his records was set on unmodified Donkey Kong arcade hardware, despite some convincing technical evidence to the contrary.

Now, new photos from a 2007 performance by Mitchell seem to show obvious modifications to the machine used to earn at least one of those scores, a fascinating new piece of evidence in the long, contentious battle over Mitchell's place in Donkey Kong score-chasing history.

The telltale joystick

The photos in question were taken at the Florida Association of Mortgage Brokers (FAMB) Convention, which hosted Mitchell as part of its "80s Arcade Night" promotion in July 2007. Mitchell claims to have achieved a score of 1,050,200 points at that event, a performance that was recognized by adjudicator Twin Galaxies as a world record at the time (but which by now would barely crack the top 30).
