Ah Nintendo, when you go wrong, you go wrong in a big way.  The Virtual Boy was Nintendo's attempt to introduce a third platform to their line-up.  An odd machine.  It ran on batteries so was portable in the narrowest sense.  The user would place their head on the visor and experience three-dimensional video gaming.  The effect DID work rather well and a number of fun games were created, unfortunately all the graphics were done in red vector (Red lines) which was headache inducing and annoying. 

  At one point I collected almost all the Virtual Boy games including the Japanese titles, but later sold them for money to pay bills.  I retain one or two titles in the event I ever feel like turning the system on.  Which never happens.
