Presuming that the player has recently started a New Game, in Pokémon Green, after switching Oak's Parcel with the first Pokémon various bytes will be 'shuffled' including one which will make Professor Oak appear outside Pallet Town and importantly a combination of bytes making the next warp relevent to a particular number of steps the player has taken.

The Doko-Kashira Door Glitch is a less commonly known glitch which is exclusive to the Japanese version of Pokémon Red and Pokémon Green. It involves the manipulation of the location of where the next door (or entrance) will take the player to. It is mainly used for Speed Running videos for Pokémon Green as one could force the next door that the player enters into taking him or her into the Hall of Fame.

This glitch no longer exists in non-Japanese versions of Pokémon Red, and Pokémon Blue because it involved the player using the Select button to switch Pokemon as well as items; this feature was removed in Pokémon Blue, and non-Japanese versions of Pokémon Red possibly due to the fact that it could affect the game into considering that the player is switching both a Pokémon and an item.

Explanation

Beyond the legitimate number of Pokémon slots (up to six), data exists which corresponds to information for other bytes within the game. The Doko-Kashira Door Glitch involves the player switching the second item (Oak's Parcel) with the first Pokémon so that data for the next Pokémon warp can be manipulated to match with a relevent number of extra steps that the player moves; this effect becomes permanent until the game is turned off. Since the ability to switch items was removed in Pokémon Red, Pokémon Blue and Pokémon Yellow this glitch is only available in Pokémon Green.

Requirements

1. Willingess to start a New Game to perform the ideal method; this is optional, however if the player uses his or her existing Save File it is extremely difficult to find another method because this glitch can potentially alter any byte within the game, if some bytes have been written a value other than 00 this could potentially crash the game if these bytes are shuffled.
2. No other requirements are necissary, as items will be obtained when performing the glitch.

Method (to warp to the Hall of Fame)

1. The player should firstly start a New Game.
2. The player should withdraw a Potion from the PC, so that he or she has one item.
3. Walk out of the door and procede into the tall grass, wait until Professor Oak takes you into his lab.
4. Choose any starter Pokémon
5. After Gary chooses his Pokémon, attempt to leave Professor Oak's lab.
6. Either defeat or lose to Gary and then procede out of the lab and through the grass on the way to Pewter Town.
7. Procede to the Pokémart (known as 'SHOP' in Pokémon Green) and recieve Oak's Parcel.
8. The player should procede back to Pallet Town but ensure that he or she enters a wild Pokémon battle on the way.
9. Move to the Items option and use the Select button on Oak's Parcel.
10. Select 'Cancel' and then select 'PKMN'.
11. The cursor should still be white, choose Bulbasaur to switch it with Oak's Parcel.
12. Check Bulbasaur's moves on the 'Fight' screen, to check that the game has not altered any undesirable bytes.
13. If Bulbasaur's moves have not been changed run from the Pokémon battle and then walk exactly 73 steps, landing the last step in Gary's house in Pallet Town.
14. The player should be near the house where HM02 Fly is normally obtainable, walk another 5 steps to the right and the move down so that it looks like the player is attempting to move through the house's ceiling, it is the spot one step north of its right hand corner.
15. The player should appear in the northern section of the Cycling Road House, walk 9 steps and aim the last step to be through the exit to the north-east corner.
16. Walk an extra 45 steps eastwards aim the last step to be through the double doors of Celadon Department Store (the door to the right.)
17. The player should now be in a glitched version of the Hall of Fame room.
