Quoted from viper001:... did the presenters not bring a longer extension cord to plug it into another outlet/circuit?
You do understand that low voltage issues are very common at pinball shows? Adding a longer extension cord to a low voltage problem will only make the problem worse. It's pretty simple really: Longer cord = more resistance = lower voltage.
Roger Sharpe has approved the game. By promoting these conspiracy theories here, you insult Roger IMO. I'd ask you nicely to stop, but I doubt you'd listen.
