This happens sometimes when you run MAME through Windows, or if you playback with the wrong version. I haven't watched his recording, but maybe someone else has.(posted 9361 days ago)BTW, your score has been zeroed on this romset for playing below default settings. You might want to check the rules page if you're unfamiliar with recording policies here. Anyways, I'm sure you can recover it easily enough with some more play.
