Oh, I OCDed through my MAME set not so long ago, perhaps some months ago, to make a favorite set of mine to include with LaunchBox, so I went through every single game, and there were quite a few I didn't know.
Btw, I'm at the moment, since some month, setting up a complete fresh and new LaunchBox install, so I go through every single game of every single system because I only want to include what I really like, there's also a lot of trash, and that would only overload the setup. I really enjoy doing it, consumes a huge amount of time, but lucky me, I do everything at work, so no need to stress at home
