Gots the 3850 english though, should be same. It may be a bad rom, does it work running under normal mame on the pc...

My Galaga (namco) works and I just tried my (set 3) it works as well...

Try grabbing one of these two from a site and see if works.

Also be sure that you do a soft reset after you don't get a game to work, I've found that I try a game and it craps out and the I try games, I've gotten to work in the past, and they do the same thing.

Happy Rom Hunting.
