Go to Arbiter's Grounds and jump into the quicksand (letting Link die). Right when Link's hand is right about to go under the sand, press the Home button on the Wiimote and then Reset. You will find yourself at where the Title Screen occurs, with none of the usual information around the screen (such as controls or map). It is very similar to the Eldin bridge area, but with different coloring. DO NOT press any buttons on the Wiimote, or the game will crash. You can jump off a ledge to get out of the area (by dying). You'll end up at the real Eldin Bridge area. If you jump off again (and die again), you will end up at the same area on Epona.
