Major Glitches are glitches the community has determined are too severe for No Major Glitch Speedruns. Most of these lead to significant breaks in the sequence and logic of the game.

MG Speedruns

The following glitches are allowed in MG Speedrun categories unless otherwise noted. These runs may sometimes be called "unrestricted" because there are almost no limitations on what's performed, although RAM Preparation and out-of-bounds misslotting tend to be banned even in these runs.

Exploration Glitch (EG)

Exploration Glitch (or EG) refers to a subset of glitches that manipulate Link's layer in the underworld. Often this leads to Link being able to get "under" the map in the underworld, and since every room in the underworld is technically part of the same map, this allows him to easily travel throughout the underworld. This glitch is extremely powerful in an Any% context, allowing players to reach the credits in under two minutes. While it's still a powerful glitch in other MG Speedruns, it's limited in many situations by how Link can't interact with most sprites while in EG as well as specific rules regarding where/how he can enter and exit the state.

There are many ways to activate EG, including normal OOB glitches, underworld YBAs, underworld Mirror Jumps, midair S&Q, jumping into voids, offsetting the camera (for example with bumpers in Skull Woods) and using the 1.0 pit in Tower of Hera. For more information about EG and how to perform various speedrun applications of it, see its page.

Transition Corruption (TC)

Transition Corruption (or TC) refers to a subset of glitches which are accomplished by bypassing or corrupting a door transition on the underworld. These can be accomplished in a variety of ways with many different effects. See its Main Page for more information.

Somaria Transition Corruption (STC)

Main article: Somaria Door

A glitch which spoofs data inside rooms, or overwrites completion flags in a room. This can cause chest contents to change, refill chests, regenerate keys, and toggle the "holes hurt players" flag which allows for some Wrong Warps.

Yuzuhara's Bottle Adventure (YBA)

A YBA is a glitch that results from Link using a bottled potion at the same time he touches a screen transition. This can be used for typical TC effects, but in some contexts, it can be used to trigger an underworld fake flute.

Underworld Fake Flute

Underworld Fake Flute is a glitch that occurs when Link performs a Blue YBA on a subtile transition or a Green YBA on a supertile transition. When this happens, the flute menu is called. Fluting in the underworld, which is of course never meant to happen in normal gameplay, leads to a very powerful game-state called Plaid World. Plaid World is considered a state on-par with EG and is therefore banned in MG runs that ban EG, even if the run allows other forms of Transition Corruption.

Wrong Warp (WW)

A Wrong Warp involves using a hole in a room to transfer the player to a room which is not intended to be accessed from the former. Some holes can accomplish this by default, such as Ganonpot or the Turtle Rock lava dive. Others require transition corruptions to change the behavior of the hole or to create holes in rooms that don't normally have them.

Misslotting

Misslotting is a class of glitches that involve loading ancillae into incorrect slots in the game's memory. This can create a variety of effects, including Hookpush, Hookclip, and Overworld Conveyor.

If the player misslots ancillae outside the table reserved for them, this is considered out-of-bounds misslotting, a glitch capable of letting the player achieve Arbitrary Code Execution. Because of this power, it is banned in MG Runs outside of ACE RTA.

RMG Speedruns

The following glitches are allowed in MG and Restricted Major Glitches (or RMG) Speedruns. These glitches have a reduced power level compared to the ones above.

Out of Bounds (OOB)

Specific manipulation of the game engine's collision detection to bypass a boundary. On the underworld OOB results in Link being outside a room's walls, but without freedom of movement across the underworld map (that is EG). On the overworld OOB results in bypassing an obstacle, such as a wall or cliff. Methods to achieve OOB include Clipping, Teleports, and mirror jumps. Some applications of OOB can automatically lead to EG.

Screen Transition Glitches (Overworld)

A subset of glitches using screen transitions on the overworld.

Mirror Wrapping

Activating the mirror on the same frame as a screen transition to warp across a screen.

Yuzuhara's Bottle Adventure (YBA)

A blue potion YBA activates a Fake Flute. Using a green or red potion to activate a YBA on the overworld corrupts the screen's data, allowing the player to bypass some obstacles.
