Sorry for being a little vague. ClrMame Pro is what I used to update the roms. But, when I verified them they did list as being bad. The problem seems to be that Dig Dug is missing file 136007.109 and Galaga is missing gg1-7b.2c, prom-4.2n, prom-3.1c, and prom-2.5c. It doesn't seem to create these files when updating. I guess I just got a couple of bad ones. Thanks for the reply.
