To do this you need a ROM or you need to take apart your controller
You must do this with a ROM on your computer, or take the casing off the controller and press the parts that are attached to the buttons to do this glitch. Hold down and then up, and you should be moving up while being backwards. Then go through a door, and you should be in a really weird room. Do this in Hyrule castle and you may be able to navigate between dungeons, getting close to the end of the level.
