Twin Galaxies contacting Guinness for copies of their 1980s video game records submitted by Twin Galaxies
Perhaps Twin Galaxies can contact Guinness Book of World Records and request all documentation that was submitted for the 1984 & 1985 Twin Galaxies sponsored events (1984 & 1985 VGMTs and other Guinness related events) whose records appear in their books. Guinness may still have a trove of valuable documents in a file cabinet somewhere that could help to actually validate or invalidate some of the scores in question, like the Kung Fu Master record. Just having locations of the game, the witnesses who watched the game, and the length of game might provide clues to the validity of the score. I would think a simple email request from Twin Galaxies could get the ball rolling there.
