Nintendo Virtual Boy

The Nintendo Virtual Boy is the worst gaming peripheral ever made, a 1995 "portable" VR headset that displayed monochrome red graphics and caused splitting headaches within minutes. Its tripod-mounted visor achieved a mere 384×224 resolution per eye, and it sold fewer than 800,000 units before being discontinued after just six months. This failure is far more catastrophic than #3 R.O.B., which at least served its purpose as a post-crash trojan horse, while the Virtual Boy offered no redeeming value and remains Nintendo's most embarrassing hardware misstep.
