1-you could, set it up on something, its not easy to track down one without the entire console.
2-An ac adapter AND batteries. The ac adapter is the SNES adapter which you can use, or 6 (i think) double a batteries in the controller's backside (an additional adapter is needed to take use of the plug in way, its a box like the one that comes with the controller just with an outlet).
3-possibly a way, but why would you need that? its fine where everything is. Im sure Nintendo looked at all the possibilities on where it could go. Not trying to flame here.
4-look online? google "virtual boy eye cover replacement accesory to buy"
5-Sadly, VB has very expensive games and only 15 or so VB games in its library. Wario World is the best one on the system, you CANT miss that one if you are anywhere near VB collecting. Also Telero Boxer.
6-It needs a controller, and its hooked up via the VB. A stand is a must, but stacked on some books or something is about the same effect-still leaves a stiff neck.

hope at least 1 point helped.
