In this video, I try to enumerate the charges against Billy Mitchell, and establish a common ground for discussing the controversy.

UPDATE Apr 12, 2018: As of this morning, TG removed all of Billy's scores, including non-DK ones, from their scoreboards.
UPDATE Mar 21, 2018: There's been some new information on this that's worth clarifying. The versions of MAME that produce the "girder finger" have now been verified as all versions prior to .122, depending on the refresh rate settings used. Additionally, Billy has admitted that the board swap video was staged as a stunt to promote Robert Childs' YouTube, and not as a verification mechanism. END UPDATE
CORRECTION: At some point in the video I describe the orientation of the 1.04M and 1.05M as incorrect. This point is overall correct, but my comments about it were not; they were not upright, but rather were simply rotated the wrong direction. They were essentially flipped 180* from what they should have been. END CORRECTION
I am not involved in the dispute! I only condensed the statements and arguments others have made. I'm happy to take corrections, but for specific and technical questions you are better off asking in the threads.
