Stephanie Rogers (http://www.hipchick.com) plays the voice of The Machine. 10/27/2010 A user reports that ROM version L-7 has a multi-player bug in it and is not recommended. The error is: If any player joins the billionaire's club, after they drain and their bonus is collected, the machine will reset. L-6 does not contain this bug. Artist John Youssi provided us the following information:I painted the backglass based on a rough sketch Python gave me. I re-sketched the whole thing, adding detail while tightening it up. Python was the artist for the cabinet while Kevin O'Connor inked only. I remember Python doing all the art except for the backglass. Plus it all looks like his style. We saw Kevin O'Connor's name listed among the Team Credits on a playfield plastic near the left flipper, although he only inked the playfield. He confirms this information to us:Looking at the playfield, I sort of recall dreading to ink all those circles in the middle and thinking how insanely intricate Python's pencil was, but that's it - inking only. I had great respect for Python's artistic ability and felt honored to be trusted with part of the production of his project. Python was big on giving everyone credit.
