SNES Zelda completed in a very quick manner by traveling in an alternate dimension through the walls. The basis of the trick is to enter a corridor or staircase by holding left+up+right at the bottom of the stairs. Note that you need the patched version of Snes9x to play the movie file.

Now 2.9 seconds faster than the preceding version due to new glitches involving doorways, stairs, and pressing three directional buttons at once.
