You got a new email as well My parser should now be able to return all missing entries and export individual missing lists based on the Software Lists. That should help you a bit
I will build a GUI, compile it and send you the little program, so you can run it every time you want to check what's still missing in history.dat that's present in the latest Mame XML/Hash XML files. It generates all missing lists (over 500 of them) in a little more than 10 seconds. You should have it in a few days.
