Angelo Berretta

Good morning everyone, I've jumped into big box few weeks ago and I found it astonishing. I started setting up basically only mame, because i believe it's the hardest to tune up and to make it work properly. I've noticed the video theme linked to the vector game "battle zone" it's linked to the game "mayday". I've been trying to cancel and import it again,but it doesn't work....it looks that's the only video available. Does anyone had the same issue?... there's any upgrade i miss to find out?. Thanks a lot have a good day Angelo
