Glitches in Majora's Mask 3D

Fierce Deity Link Anywhere
In order to do this glitch you must have obtained all of the mask including the fierce deity mask. The only problem with this glitch however is that opening doors while wearing the mask will crash the game.

To do the glitch you need to have an item which can be used anywhere in the X button slot and the Fierce Deity mask in the Y button slot. Then go into first person perspective and open up the items page, swap the X and Y buttons around so the X item is Y come out and then the Fierce deity mask becomes highlighted. This bit takes a few tries but you press the Y button and the Y button on the touch screen which then allows you to use the mask.
