Nintendo reveals new info on BotW VR mode
"Once you've updated the game's software, it's easy to use. During play, open the menu screen, select System, and select Options. Then set the Toy-Con VR Goggles option to ON, and simply insert your Nintendo Switch console into the VR Goggles and attach its Joy-Con controllers to the sides. When you look through the VR Goggles, you'll see the world of Hyrule stretching out before you in VR!"
