Sorry. You can bet the perfect pacman is bullshit too. Being done in 1999, could have been emulation, or any other hackery off an original board which has been mentioned for many years.
Quoted from Neurocrasher:It sounds like Twin Galaxies has a problem with official events and judges, too, as it's my understanding so many of Todd Rogers' illegitimate scores were verified by official refs, some of which were supposedly done at events. Twin Galaxies needs a complete replacement, something like highscore.com. I won't pretend HS doesn't have problems with cheaters, but they seemingly have no problem calling them out (unlike Twin Galaxies... seriously, these scores stood for waaaaay too long).
As long as we're not talking a high profile world record like DK, I'm okay with video shot at home as long as they do one take (no cuts) and remove the camera from the tripod to clearly show the PCB connected to the cabinet and screen they're playing on. The board might be suspect, but you could rule out MAME at the very least. Streaming live on Twitch is even better than video, but there are cheaters there, too.
I almost feel bad for Mitchell because he was a good player and at least some of the scores removed are legit. I mean, I'm not going to lose sleep over it or anything, but I still believe he was (probably) the first to get a perfect Pac-Man. Someone on Reddit's speedrun sub pointed out that Steve Weibe is now the first person to get a million points on DK, though, so I guess that's a silver lining.
