It is similar to [[tweaking]] and the [[surf glitch]] in [[Generation IV]]. It can be used to enter the [[Hall of Fame]] without battling the [[Elite Four]] or the {{pkmn|Champion}}. It is still possible to trigger this glitch in the international releases of {{game|Red and Blue|s}} - however, it will have different effects from the japanese releases, and it will not cause the player to warp.

The '''Dokokashira door glitch''' takes advantage of the fact that in {{game|Red and Green|s}}, the player is able to switch the slots of [[item]]s as well as Pokémon. However, an oversight of this feature was that if the player were to press the Select button on the items screen and then exit out of the menu, the game will still remember the position where Select button was held down previously.

When the player switches the second item in his or her [[Bag]] with his or her first Pokémon, it will force the game to switch the second Pokémon (which is unexistent) with the first one. In this particular early-game scenario, it switches the end of list marker to the first position. This confuses the subroutine which applies the [[Poison (status ailment)|poison damage]] in the overworld, causing it to check Pokémon beyond the sixth slot for poison damage, decrementing massive amounts of RAM addresses while thinking they are party Pokémon's health points.

Dokokashira door glitch still exists in {{game|Red and Blue|s}}, but it's not available in early game, as select glitches were removed in international releases. However, triggering this glitch is still possible by [[Memory corruption|corrupting the memory]] with [[Super Glitch (move)|Super Glitch]] or [[ZZAZZ glitch]]. Some of the japanese edition effects are still present, such as map tiles changing every 4 steps, or random Pokémon fainting even though nothing is poisoned. There also exist some effects which didn't happen in {{game3|Red and Green|Japanese Pokémon Red and Green|s}}, like glitchy music and changing item quantities. In international releases, Dokokashira door glitch does not change the warp location.
