I can't find much, but they made the same thing for the Genesis. http://farm5.static.flickr.com/4101/4907932751_fec08df922.jpg

That's a game cartridge adapter for a series of sports base games, baseball, basketball, etc. I don't recall the manufacturer's name. It also came originally, with an overlay for the Nintendo screen that had the outline of the game field for each specific game.
