Home is one of the locations in the game the player is never meant to be able to return. However, certain International versions of the game include a glitch where the player is able to re-enter Home, and thus effectively backtrack the game to an earlier point, where all the scenes play out as if the player had never been to Home previously, except that the player will have Yuna in their party.
To initiate the glitch the player must travel back to the Bikanel Island after acquiring the airship. In the screen before Home, the player encounters a woman who summons Dark Ifrit. It is not necessary to fight Ifrit for the glitch to play out. The player must talk to the Al Bhed on the left and get as close to him as possible. As the man speaks, the player must tap and Tidus is able to continue walking, hopefully slipping into the next screen and triggering the events at Home. If the player is defeated by Dark Ifrit, they may have to leave and re-enter Bikanel Island for the glitch to work.
The glitch has some side-effects: as the game treats the event as if the player is entering Home for the first time, the storyline will play the same events again, and there is a chance that when the player enters Via Purifico with Yuna, the gate might be closed, trapping Yuna on the wrong side and preventing further progress. The closed gate may be due to the player closing the gate the first time they were there, and after the event has been triggered once the gate can never be re-opened. The player should avoid summoning any aeons against Evrae, as it will freeze the game. It has also been found that when the party is supposed to fight Evrae Altana, the enemy may never appear.
Yuna will have to progress through the maze without her guardians, but the teleport puzzle will have already been solved. Also, all the treasure chests the player will encounter again have already been opened and are thus empty. The Dark Aeon, however, will not come back until the player reacquires the airship.
