IIRC in the ancient past I discovered at least one of them didn't exist under that name (shocker!) by attempting to create a full Sega list from sources outside System16, then comparing to System16, and pattern-matching the differences. Then I made fun of Sixtoe until the cows came home.
I don't honestly remember writing the notes that btribble has, I think that was at least partially Justin, but I suppose it's possible I did. Some of these things are beginning to fade in my memories.
Let's not forget my new favorite at System16, Sega "Space In Bingo" - Invinco or possibly "Space Invinco" :P (and yes I told Sixtoe about it)
