I saw about the last half of the show. Am I to understand that he put all that time and effort into setting a new record and the game messed up? Didn't he know the game was not 100% or maybe all that play was too much for the game to handle. Extra cooling in the cab might have helped.
Here's the thing, back in the day, these machines were designed to run almost 24/7. I remember some arcades that never turned their machines off. Heat's not really an issue either. Did you know that a 386 PC did not even have a fan on the CPU? That's how much heat was a non-issue as recently as early 90's... I think my 486 was the first PC I owned that required a heat sink. Then the Pentium required a heatsink + small fan.
Anyways, what you missed in the first half was the guy gets a machine. He tries it out, in his garage. He plays it for a few minutes, and it resets. Does this over and over.
His buddy who is his "tech" checks the boards and finds that some connectors were loose. Fixes it all up, he starts playing again ("training") and every time he gets to around the 1 million points mark, the game resets.
So fast forward some time, he finds a game board seller online that GUARANTEES the board he buys will have been shopped, and will stand up to the duration he needs.
So he gets that board, and then they take the machine to that Game Galaxy store. (Why? Some publicity thing. The store will buy the machine from him after he breaks the record. + he intends to break the record at the store. So the store will own a piece of game history, so to speak).
So up comes a long weekend, he's all set up for his 3 day marathon to break 80 million, and he starts playing (while recording on video tape). I don't know how many HOURS later, but he hits 30 million, and BAM the game resets.
