Superspeed

Superspeed is a very helpful glitch, that allows link to run very fast whenever there is a climbable stairway/ladder around. In this state, Link can use items, however can not use his sword. You can cancel this state by pressing A, screen transitioning, or jumping off of a ledge, to name a few. Keep in mind that this glitch requires the Pegasus Boots, and JP v1.0.

Spindash Method

Using Spin Dash, this glitch is relatively simple. Execute spinspeed by charging a spin attack with B, and then pressing A one frame after letting go. Afterwards, walk onto a ladder/stairway, and when you walk off, you'll have superspeed!
