Earlier in the thread, at least, in general terms. It was a multi-step process due to a glitch in certain Game King units that enabled a player to hit a paying hand while playing a lower denomination that could then be essentially transferred to a higher denomination and was then paid out at said higher denomination. For example, a nickel denomination royal ($0.25 bet, $200) could become a dollar denomination royal ($5 bet, $4,000) and other possibilities. For it to work, though, it had to be a handpay.

As far as the exact process of causing this, only the manufacturer, the guys to actually do it and anyone they may have told would know that. There was a list of steps as to how it was done once published, but many people claim that list is incorrect. I don't know whether that list is incorrect or not.
