Editing Yuffie Warp

Yuffie warping is a glitch only present in the PC version of the game. Similar to the [[Wrong Warp]], it allows the player to be warped to incorrect locations when attempting to recruit Yuffie. This trick is used heavily in [[All Bosses (Warps)]].

== Execution ==
To perform the Yuffie warp, the player must make a save file on the world map in or near a forest where you can encounter the Mystery Ninja enemy. Then they must load another save on a field that the player wishes to warp to, and enter a battle. In the battle, the player must intentionally trigger a game over. The player must then load their save in the forest, then find and defeat Mystery Ninja. Because the PC version of the game does not clear memory after a game over, it will erroneously reload the field previously died on instead of the field where the player can recruit Yuffie. If the player triggered the game over in a scripted fight, e.g. a boss battle, the player will be warped directly back into that fight.

== Encountering Mystery Ninja ==
There is a flag in the game that determines if the player can encounter Mystery Ninja, stored in memory at <code>DC0A61x01</code>. By default, this flag is off, and is first turned on after watching the Turks cutscene in [[Mythril Mines]]. If the player has not recruited Yuffie, it will also be turned on in the [[Cargo Ship]], or at the end of the first [[Cosmo Canyon]] sequence.

The game will check if the player has recruited Yuffie either by checking if she is present in the global party, or by querying a separate flag at <code>DC0AABx01</code>. If the player desyncs these values through sequence breaking and/or using the [[Debug Room]], it is possible to encounter Mystery Ninja even after recruiting Yuffie.
