Updating the romset
OK. So I finally got some time again, and decided to do something about all the things I wanted to write about here on mameblog.com. Of course, since it has been a while since my last post, and that was about upgrading the packages, there is a bunch of new packages, so I'm going through another iteration of package upgrading.
But since I am also updating my romset, I thought I would share a little information about how I maintain my romset using the advscan utility. Way back I downloaded a complete romset (I think it was for version 0.70), and ever since, I have been using differential updates (one for each MAME version) and verifying with advscan. Let me explain how I apply one romset update at a time and check for any missing ROMs. Then I will give a few hints on how to fix it if it turns out some roms are bad.
