Found the link. Ran across while shopping for a new video card.
I remember when the Sega Master System (pre Genesis) first came out I had the wired 3D glasses that plugged into the slot on the back. Used to play 3D Zaxxon and Missile Defense and some others that I have forgotten. With some games it worked very well and others not so great. Zaxxon was the best by far. Of course, those games were designed for 3D and looked like crap without the glasses.

NVidea web site does have a steroscopic 3D driver for free download on GeForce models. Who volunteers? I think it would give me a headache.
