The '''Trainer House glitches''' are glitches in {{game|Gold and Silver|s}} that affect the Trainer in the [[Trainer House]]. It is caused by corrupted RAM for save data from attempting to modify the [[time]] just after a [[Mystery Gift]] or a trade, or [[glitch dimension]]s caused by viewing the entries of [[glitch Unown]].

==Corrupted link battle/[[Mystery Gift]] method==
[[File:Corrupted Link Battle Gold and Silver.png|thumb|x144px|A corrupted link battle obtained using over 6 Pokémon]]
[[File:Glitch Butterfree Corrupted Link Battle.png|thumb|160px|left|A glitch Butterfree that appears during a corrupted link battle]]
Sometimes during a link battle—possibly due to a dusty, damaged, or loose link cable—one of the players can send invalid data to the other player. This triggers a corrupted link battle with a different result for each player. Usually the opponent withdraws the Pokémon which was fighting to send out a glitch Pokémon that wasn't in their party. The players will battle against an AI using mostly the Pokémon which were in the party of the opponent but also glitch Pokémon usually over level 100 and {{status|asleep}}. In particular, many corrupted link battles trigger a {{p|Butterfree}} with a large amount of {{stat|HP}}, making it virtually undefeatable and forcing the player to restart the game. If a player had an {{pkmn|Egg}} in their party, then the Egg can be sent out by the AI and appear with the sprite and the moves of the Pokémon which is inside the Egg, but it will immediately faint.

A corrupted link battle has a good chance to corrupt the [[Trainer House]] and the mailbox of the player who received the invalid data, while it won't affect the player who sent the invalid data. The [[glitch Trainer]] obtained in this way can be battled, but the screen may display "Waiting...!" as if the player was in a link battle. Once the message "Waiting...!" is displayed, the [[game freeze|game will freeze]]. A corrupted link battle can be forced by having a Pokémon with an irregular HP bar.

It is also possible to cause Trainer House glitches if the last [[Mystery Gift]] was corrupted by an infrared interference. In this case, the item received will be unaffected, but the Trainer House could be corrupted.

==Time method==
[[File:Trainer House Level 0.png|thumb|160px|left|A {{?|5}}, which uses the same sprite as its Trainer, but with less detail and uses the color palette as the Pokémon it is]]
[[File:Trainer House glitch party.png|thumb|160px|A Trainer affected by the glitches; all of his Pokémon have fainted]]
This method usually occurs if the player sets the [[time]] back just after a trade or a [[Mystery Gift]]<!--How?-->. The Trainer in the [[Trainer House]] is replaced with [[Pokémon Trainer|{{PK}}{{MN}} TRAINER]] Thomas<!--Regardless of time?-->. [[Pokémon Trainer|{{PK}}{{MN}} TRAINER]] Thomas is displayed in the receptionist's dialog as a series of "9" and letters. This [[Pokémon Trainer|{{PK}}{{MN}} TRAINER]] is displayed in battle with six Pokémon, which are all fainted, and sends out a level 0 [[Five question marks|?????]] with his same sprite causing an immediate [[game freeze|freeze]]. [[Pokémon Trainer|{{PK}}{{MN}} TRAINER]] Thomas doesn't corrupt the player's [[mail]]box, and can be fixed by doing a new [[Mystery Gift]] or a trade, which should replace the missing information. {{-}}

==Unown method==
[[File:Glitch policeman.png|thumb|160px|left|A glitch Mystery Gift policeman may appear on the second floor of any Pokémon Center, and will give the player a random item]]
[[File:Level 205 Moltres.png|thumb|160px|A Pokémon over level 100 of the glitch Trainer]]
This method overwrites data associated with the mailbox and Trainer House with a certain index number depending on the hexadecimal identifier of a viewed [[glitch Unown]] in the [[Unown Mode]]<!--and wild? Though IIRC #00 just leaves a blank screen-->, causing alterations to the game. If the new value triggers a [[glitch Unown]] then the [[time]] will be reset and the Trainer in the [[Trainer House]] will be displayed without a valid name, but with six Pokémon. Battling the Trainer twice (or even once) in one day often either freezes the game or triggers the [[glitch dimension]]. The [[glitch Trainer]] may have Pokémon with glitch [[status condition]]s and Pokémon over level 100, and may have Pokémon with impossible movesets and Pokémon with a series of "?" instead of their name. Some glitch Pokémon know a glitch move which, if used, causes the message "But nothing happened" to appear, followed by the game entering the [[glitch dimension]]. Additionally, if the player checks Unown's Pokédex data in a Pokémon Center or inside a city, there will be a {{tc|Policeman}} on the second floor of all Pokémon Centers, as if the player had received a Mystery Gift. When spoken to, he says "Hello! You're <player>, right? I have something for you." If the player chooses "YES", the Policeman will say "Here you go!" and the player will receive an item (this item is related to the glitch {{p|Unown}} index number). This allows the player to obtain various glitch items, such as the [[Teru-sama]].

===Registering glitch Unown===
To register a glitch Unown in the Unown Mode, the player may obtain a [[Five question marks#Hex FF)|????? (Hex FF)]] as a bad clone from the [[Celebi Egg glitch]]. If the ????? is placed as the first Pokémon in the party, the player can use the "MOVE {{PK}}{{MN}} W/O MAIL" option to withdraw over 6 Pokémon. This corrupts RAM data located past the expected end of the {{OBP|Pokémon data structure|Generation II}}, although there are only a limited amount of Pokémon that the player can withdraw before the game freezes. If details about a 'post-6' Pokémon conflicts with data about Pokémon in the Unown Mode, then it is possible to replace entries with glitch Unown, provided that the player already has the Unown Mode, for example the index number of the current fourth move's PP of Pokémon #11 conflicts with RAM data associated with the first Unown. It is possible to replace the first Unown with a glitch Unown this way provided that the player used [[PP Up]]s to raise its associated index number past 26. In the process of obtaining glitch Unown, the player will be corrupting the values of other RAM addresses such as those determining seen or owned Pokémon in the [[Pokédex]], or the number of options on the menu.

If the player added a [[glitch Unown]] which activates a glitch dimension, then there is a possibility that it will trigger the Trainer House glitches depending on its index number. Since getting a [[glitch dimension]] from glitch Unown only partially saves the game, any values changed prior such as the number of Pokémon seen and owned in the Pokédex will be returned to normal, provided that the player did not already save from the menu. A list of glitch Unown which give obtainable Mystery Gift items can be found below.

===List of obtainable 'Mystery Gift' items===
Below are a list of Mystery Gift items obtainable through [[glitch Unown]], based on the viewed hexadecimal identifier.
Some hexadecimal values can trigger two or more items depending on where the glitch Unown is displayed. Missing hexadecimal values don't trigger any item.

[[File:Glitch mailbox gold and silver.png|thumb|160px|A mailbox corrupted by this glitch. The messages may be signed from unused character strings]]
It is rare that the Trainer House data is corrupted without simultaneous corruption of other areas of the save. 
[[File:Trainer House glitch Green message.png|thumb|160px|left|A glitch message in a corrupted mailbox. It's signed by GREEN]]
Most commonly, the player's [[mail]]box is corrupted. If so, the list is not properly terminated. Some of the messages may be signed from unused character strings, such as {{ga|Blue|GREEN}} (a default character name remnant from the Japanese version), and some may freeze the game or reset it into a glitch dimension if they are read. If the player gives one of these messages to a Pokémon, and the mail appears as a purple version of the [[Flower Mail]] from the mailbox, the game will transform it into an equivalent item depending on its index number. All invalid Mail will appear this way, except for index number 255, which causes the screen to become blank.

If the player has an excessive number of glitch messages the overworld will become corrupted, the screen may turn black and the [[Non-player character|NPC]] sprites will become corrupted sprites. If the player has around 230 messages the game will freeze or reset into a glitch dimension.

By reading or scrolling past these messages, a series of side-effects may occur:

* The options "[[Bag|PACK]]" and "[[Save|SAVE]]" will disappear from the menu.
* Wild Pokémon and Trainers not inside the Trainer House may become glitchy. In this case, the Trainers will have the same name and Pokémon as the last Trainer fought in a link battle. If the player hasn't performed a link battle, their first Pokémon will be a {{p|Wigglytuff}}. The screen will display "Waiting..." when the player attempts to fight as if they were in a link battle. 
* The player's Pokémon cannot use [[field move]]s.

Another common problem is having an excessive amount of room [[decoration]]s, which may include glitch decorations placed directly into the [[PC]].
