Thanks! I love all the Sega-era "billboard" style of games. There was actually a set of SegaScope 3D Glasses for use in the Sega Master System that could render a stereoscopic effect right on a NTSC-standard television set!

I had this! I'm too young to have played the Master System in its prime, but one day at my dad's office someone put a for sale ad on the bulletin board saying they had a bunch of old game systems and games. I bought the whole lot (a Genesis, NES, Master System, and a whole bunch of games/peripherals for each) for about $80. I was maybe 12 at the time, so a decent chunk of change I'd saved up.
Those goggles were one of the coolest and least practical things ever. The effect was kind of flickery.
