Yeah seen that before. It’s definitely impressive but it’s worth noting that there are a few 3D games for the Mega Drive. Albeit games like Virtua Racing did have additional chips in the cartridge (I have a boxed copy of that cart sat behind me).
The Master System had stereoscopic 3D games too. As did the Famicom. I have both of their respective 3D addons too. Missile Defence in 3D is pretty cool. Hard to believe it’s 30+ year old tech.
