Yeah, I beat it. I beat the OoT 3D and Master Quest 3D OoT (its on the same game you get Master Quest by beating the OoT 3D). The boss is pretty easy, uses your arrows, and shoot both the hands when they are drumming, and than use the Eye of Truth to see the boss body and hit the eye, and keep doing it. you can even do it without the eye of truth, cause it's head is right near his hands when you shoot his hands.
