Hi Brian, interesting that you should mention that. I've just videoed Moon Quasar and, to be honest, it's way out on the attract mode. And I mean, way out. I'll upload a video shortly. I think I'll do a further Moon Cresta video and upload that. We should then be able to get a good comparison of all of the attract mode.
Hopefully, the MAME dev's can work their magic.
BTW, if nothing else, it shows how important it is to compare to the original hardware.
God, I miss those dark, musty arcades ....
