There are plenty of videos about it on YouTube.
Some long-haired guy (I forgot his name) tried to manipulate the score to stay the king of kong in some Donkey Kong arcade game.
Just watched someone go through it in detail. I think my favorite example of that guy's cheating was the Barnstormer world record where they stripped out all of the obstacles and the dude's score was still like 4 seconds faster than technically possible.
