(view, talk, edit)
International 'dokokashira door glitch' is an equivalent of the original Dokokashira door glitch in international releases of Pokémon Red, Blue and Yellow versions. It exploits the fact that the method of activating the glitch was patched, but the glitch itself was not, leaving it accessible in other ways.
Even though the glitch is still the same, its effects are significantly different from the Japanese versions. The most recognizable effect of the original glitch, which is warping around the map, will not work in localizations (but a similar effect occurs in Pokémon Yellow, where the south map connection changes every 1024 steps). Some of the effects are shared between the Japanese and English versions, like the corruption of map tiles.
Activating the glitch
The key to activating the glitch is to either switch the end terminator on the first place in the player's party, or delete the end terminator from the party. There are several possible methods of achieving this.
- Activating the ZZAZZ glitch with one, three, four or six Pokémon in the party.
- Accessing the Pokémon beyond the sixth slot, and swapping the 7th Pokémon with the first one. This will only work if the player had 6 Pokémon before doing the glitch.
- Activating Super Glitch with proper setup; see [thread on the forums] for more information.
Since all of the methods presented above cause memory corruption, it's not recommended to save the game after completing any of them.

- Number of items decrements every 4 steps if the quantity of the first item in the bag matches a hex number of $X8, $X9, $XA, $XB, $XC, $XD, $XE, $XF.
- If the 4th Pokémon in the party has a hex identifier of $X8, $X9, $XA, $XB, $XC, $XD, $XE, $XF, the identifier of Pokémon #2 will get decremented every 4 steps.
