Hello, Can anyone please tell me why "Tempest" shows up really weird in this? It looks like it is made up of dotted lines...game runs fine and everything, but looks weird. On the other hand, games like Star wars run fine (no broken lines). I checked in another version of Mame, and tempest runs fine. Is there any certain setttings for this one? Cheers. BTW I'm using a standard 29"tv (CRT)
