* [[List of battle glitches (Generation II)]]

===Celebi Egg glitch===

{{main|Celebi Egg glitch}}

For example, trading a level 34 {{p|Graveler}} from {{game3|Red and Blue|Pokémon Red|s}} to {{game3|Gold and Silver|Pokémon Gold|s}} will cause the Graveler to evolve into {{p|Golem}}. Since it is at level 34, it will learn {{m|Rollout}} in Gold. If it is then traded back to Red, it will still have the move but the game won't recognize it properly since it is a {{cat|Generation II moves|Generation II move}}, so it will become {{m|TM05}}.

This bug was carried over from {{game2|Red|Green|Blue}}. In [[Cerulean Gym]], the [[water tile]]s have [[wild Pokémon]] data programmed in, which allows players to [[Fishing|fish]] {{OBP|Pokémon|species}}. It was already corrected in {{game|Yellow}} and it was fixed again in {{game|Crystal}}. This likely happened because while Yellow came out after Red and Blue did, Red and Blue were already being used as the base of Gold and Silver due to Yellow not existing yet.

{{main|Trainer House glitches}}

{{main|Bug-Catching Contest glitch}}

In the Japanese versions of {{game|Gold and Silver|s}}, if the player uses {{m|Fly}} or {{m|Teleport}} to leave the [[National Park]] during a [[Bug-Catching Contest]], the game will treat the contest as still ongoing.

In Crystal, if the player [[black out|whites out]] due to {{status|poison}} damage while still inside the Dragon Shrine at [[Dragon's Den]] after receiving the {{badge|Rising}}, they can return to the [[Blackthorn Gym]] to receive the reward [[TM]] from [[Clair]]. However, due to an oversight, if the player then returns to Dragon's Den and stands on the tile directly in front of the Dragon Shrine's door, Clair will appear again and give the player another {{TM|24|DragonBreath}}, as if they hadn't already received it.

In {{game|Crystal}}, the level and time of day when a Pokémon was originally caught, hatched, or received is stored in the game data and can be verified by visiting the [[Poké Seer]]. However, this only works correctly for Pokémon met up to level 63.

In Crystal, when the player talks to [[Eusine]] in the [[Celadon City]] Pokémon Center he will report a rumor that {{p|Ho-Oh|a rainbow colored Pokémon}} has appeared in [[Bell Tower|Tin Tower]] (Ho-Oh) and leave the building when {{p|Suicune}}, {{p|Raikou}} or {{p|Entei}} appear in the party and/or storage boxes with OT and ID data matching that of the player. Due to a glitch, the English version of Crystal will only check the first five characters of the player's name. For example, if the player's name was “CRYSTAL”, then having the [[legendary beasts]] with the OT name “CRYST” and a matching ID of the player will enable the event. This is due to the player names in the original Japanese version being a maximum of five characters long and the English version failing to account for the change.

In the Japanese version of {{game|Crystal}}, address $A800 in SRAM triggers a script in the [[Pokémon Communication Center]] that may be arbitrarily set to values other than 0x00 when the game does not currently have a [[Save|save file]]; otherwise, its value is correctly set to 0x00. This causes all sort of bugs, like crashes, freezes, and other random behavior.

On the German cartridge version of Crystal, when doing the Dude glitch, trying to use the [[Poké Ball]] shows:

On the Virtual Console release of German Crystal, if the player has full boxes while the dude wants to present how to catch Pokémon, the game will [[Game freeze|freeze]]. Other languages of Crystal freeze or reset the game with the 'Game Boy Color only' message in different ways.

This occurs with any [[Stadium Cup]]. If there is a previously suspended game and the player is playing a Stadium Cup, suspending the game after a loss causes a warning message to pop up, telling the player that there is already a suspended game. If "Continue without Suspending" is selected, a rematch with the opponent who just defeated the player will be triggered, but no continue will be used.

If a Pokémon is holding a Key Item in the Generation II (such as by using the [[Celebi Egg glitch]]), this item can be deposited normally in the Metal Case from the {{OBP|PC|Stadium}} in Pokémon Stadium 2 and then transferred to another Generation II game.

For instance, this can be used to transfer a [[Squirt Bottle]] between Generation II games for the purpose of [[sequence breaking]].

Due to a localization oversight, using the [[Transfer Pak]] with the English versions of {{g|Stadium 2}} and {{game|Red and Blue|s|Pokémon Blue}} and looking up the locations of [[wild Pokémon]] in the [[Pokédex]] will instead load the corresponding data for the [[Pokémon Blue Version (Japanese)|Japanese version]].
