This is an interesting question. I personally have Backgammon, Superman, Championship Soccer, Video Chess, and Casino. Backgammon is shrink-wrapped new, so I'm not going to open that, but I dug into the others and found... nothing. None of the catridges mention anything about Special Edition, nor do the Game Program Instructions nor do the Video Computer System Catalogs. It's only on the front and rear of the boxes. Of note, Champoinship Soccer's box DOES have a gold sticker on the front that says, "Pele's Champoinship Soccer This Game Program is personally endorsed by Pele." The instructions say the same thing on the cover page. The Superman box mentions the DC Comics trademark, as does the instruction booklet as well. I thought that maybe SE had something to do with licensing, but since Pac Man and Space Invaders are not SE, I figure that theory's out. But it was fun going through the games! Love that box art...
