Mirror Displacement is a Major Glitch that allows you to place a Mirror Portal on a screen you're not physically on. This can be abused to allow Link early access to an area of the Dark World.

Explanation

The game tracks Link's coordinates in multiple ways: it tracks where he is on the current screen and it tracks where he is on the overall map. In normal gameplay, there's no conflict between these two values, but if we use glitches to jump through the bottom of a screen, the screen transition is not run and Link will wrap to the top of the screen. However, his coordinates on the overall map will continue descending as if he did transition to the screen below. Because the game references Link's overall map coordinate when placing Mirror Portals, this can be used to place Portals in otherwise impossible locations.

Applications

Pyramid Fairy

Pyramid Fairy can be accessed early, without the use of the Super Bomb, through doing a Mirror Displacement on Dark Death Mountain. First the player must Screenwrap Warp on Death Mountain. Next make your way to the bottom of the mountain and stand on the left side of the light brown patch of dirt that's just east of where Old Man Cave is in Light World and just west of the short ladder.

There's a wide range of working pixels for using the Mirror here:

  • x-coordinate range: 766-77A
  • y-coordinate range: 79B-7A9

This is a 20 pixel window horizontally, and a 14 pixel window vertically.

There are 3 quickwarp windows within the x-coordinate range. They are:

  • 777-776
  • 76E-76F
  • 766-767

After Mirroring, you need to make it to your portal that exists in Hyrule Castle Courtyard. There are a number of ways to do this and the best/fastest method will be category-dependent. Do take note that you CANNOT save & quit to Link's House and run to the portal from there. Mirror portals do not persist through S&Q.
