All 12 Spectravideo games for the VCS/Compumate
Mangia, SongMate and PictureMate were the 3 expensive titles, Mangia $250, SongMate $200, PictureMate $70, Bumper Bash 60 AUS $s
Gas Hog is the German version box, which came with the English game title cartridge (English Gas Hog box is extremly difficult to find)
Two games are known for the CompuMate, who knows if there are other titles out there.
One game which I am still missing, Chase the Cuckwagon is supposed to be a Spectravideo title too. It was distributed by Ralston Purina, written by Video Game Industries and Spectravideo (unless Spectravideo just provided the carts). So I might have to get that one day.
