==Gold and Silver==
===Bug-Catching Contest===
'''NOTE:''' The following [[glitch]]es affect all versions of Japanese {{game|Gold and Silver|s}} (1.0 and 1.1) unless noted otherwise.
 
===Bug-Catching Contest data copy glitch===
{{main|Bug-Catching Contest data copy 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 creates unstable {{OBP|Pokémon|species}} data.
 
This glitch was fixed in the international releases and in all versions of {{game|Crystal}}.
 
{{YouTubeVid|e4D6wJGGqZA|ChickasaurusGL|Bug}}
 
===Cerulean Gym fishing oversight===
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}}.
 
===Coin Case glitches===
{{main|Coin Case glitches}}
The Coin Case glitches are a set of glitches which occur exclusively in the English versions of {{game|Gold and Silver|s}}. They allow the player to run arbitrary code by exploiting an oversight in the process used by the game to print the text box data for the [[Coin Case]].
 
The Coin Case glitches are a set of glitches which occur exclusively in the English versions of {{game|Gold and Silver|s}}. They allow the {{player}} to run arbitrary code by exploiting an oversight in the process used by the game to print the text box data for the [[Coin Case]].
 
These glitches do not work in the Japanese versions and other localizations or in {{game|Crystal}}.
 
When the game is played on the [[Game Boy]] or [[Super Game Boy]] instead of the [[Game Boy Color]], the effects caused by the oversight are more limited.
 
===Trainer House===
===Present damage miscalculation===
{{main|Present (move)#Generation II}}
In {{game|Gold and Silver|s}}, the [[move]] {{m|Present}} has a damage formula of its own due to a [[glitch]]. This causes the [[level]], {{stat|Attack}}, and {{stat|Defense}} variables of the regular damage formula to be replaced. Thus, the move deals unusually large or small amounts of damage, depending on the {{OBP|Pokémon|species}}.
 
This [[glitch]] was fixed in {{g|Stadium 2}} and in {{game|Crystal}} but it still occurs in the latter during Link battles to preserve backwards compatibility.
 
===Thick Club effect error===
If a {{p|Marowak}} with an {{stat|Attack}} stat equal or higher than 256 uses {{m|Swords Dance}} while holding a {{DL|Stat-enhancing item|Thick Club}}, its Attack will be reduced by 1024 (minimum 1) during [[damage]] calculation only. This happens as a consequence of an oversight that causes the temporary Attack boost from {{DL|Stat-enhancing item|Thick Club}} to ignore the [[stat]] cap of 999 unlike other stat modifiers. During damage calculation, both the attacker's (Special) Attack stat and the defender's (Special) Defense stat are modded by 256, and, prior to that, if either is higher than 255, both are temporarily divided by 4. Thus, stats that are equal or higher than 1024 (256×4) will be treated wrongly.
 
This [[glitch]] was fixed in {{g|Stadium 2}} and in {{game|Crystal}} but it still occurs in the latter during Link battles to preserve backwards compatibility.
 
This behavior also applies to {{p|Pikachu}} holding {{DL|Stat-enhancing item|Light Ball}} and to {{p|Ditto}} holding {{DL|Stat-enhancing item|Metal Powder}}. However, these Pokémon need to receive boosts from a Pokémon that knows {{m|Baton Pass}} in order to be able to reach a stat of at least 1024.
 
===Trainer House corruption===
{{main|Trainer House glitches}}
This [[glitch]] affects the {{pkmn|Trainer}} in the [[Trainer House]] and is caused by corrupted {{wp|Random access memory|RAM}} for the [[Save|save file]] in {{game|Gold and Silver|s}}.
 
==Crystal==
===Pokémon Communication Center===
'''NOTE:''' The following [[glitch]]es affect all versions of English {{game|Crystal}} (1.0 and 1.1) unless noted otherwise.
 
===Pokémon Communication Center script bugs===
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.

==Gold, Silver, and Crystal==
==In all core series games==
===Battle system===
'''NOTE:''' The following [[glitch]]es affect all versions of Japanese {{game|Gold and Silver|s}} (1.0 and 1.1) and of English {{game|Crystal}} (1.0 and 1.1) unless noted otherwise.
====Belly Drum effect====
 
===Belly Drum effect error===
When a Pokémon uses {{m|Belly Drum}}, its {{stat|HP}} is deducted by 50% and its {{stat|Attack}} stat raised by up to 12 stages, ensuring that even the {{stat|Attack}} stat of a Pokémon with an {{stat|Attack}} stage of -6 can be maximized. This is accomplished through executing the command used by {{m|Swords Dance}} by a maximum of 6 times; however, the command is erroneously called once before verifying that HP of the user can be deducted by 50%. This means that if the user doesn't have enough HP to use the move, the Attack stat will be incorrectly boosted by 2 stages. The game will state that the attack has failed.
 
{{YouTubeVid|zuCLMikWo4Y|Dukstless|Normal}}
 
====Catch rate errors====
The [[status conditions]] of paralysis, burn, and poison, increase the catch rate by 0 as opposed to by 5.
There are four minor bugs in the [[catch rate]] formula, all of them as a consequence of programming oversights.
 
The {{DL|Poké Ball|Love Ball}} only gains a [[catch rate]] of 8× on {{OBP|Pokémon|species}} of the same [[gender]] and species as the player's Pokémon, rather than on Pokémon of the opposite gender.
The [[status conditions]] of paralysis, burn, and poison, increase the catch rate by 0 as opposed to by 5 as it was intended.
 
The {{DL|Poké Ball|LoveMoon Ball}} onlyis gainssupposed ato multiply the [[catch rate]] ofby 8×4 on Pokémon that evolve with {{OBPDL|PokémonEvolutionary stone|speciesMoon Stone}} ofbut theinstead samedoes this on [[genderPokémon]] andthat speciesevolve as thewith {{playerDL|Status condition healing item|Burn Heal}}'s. PokémonSubsequently, rather{{DL|Poké thanBall|Moon onBall}} Pokémondoes ofnot thehave oppositeany genderadditional effect and always acts like a [[Poké Ball]].
 
The {{DL|Poké Ball|Moon Ball}} was intended to multiply the [[catch rate]] by 4 on Pokémon that evolve with {{DL|Evolutionary stone|Moon Stone}}, but was erroneously programmed to apply this effect on [[Pokémon]] that evolve with {{DL|Status condition healing item|Burn Heal}} instead. Subsequently, {{DL|Poké Ball|Moon Ball}} does not have any additional effect and always acts like a [[Poké Ball]].
 
The {{DL|Poké Ball|Fast Ball}} only quadruples the catch rate against the first three of all fleeing Pokémon: [[Magnemite]], [[Grimer]], and [[Tangela]].
 
===Celebi=Ditto Egg glitchassumption====
Any {{OBP|Pokémon|species}} that uses {{m|Transform}} is regarded as a {{p|Ditto}} in its new form; this means that if the player catches a {{p|Mew}} or a [[glitch Pokémon]] which has used the move Transform or a Pokémon which has used Transform via {{m|Mirror Move}}, instead they will obtain a Ditto. Mew turning into Ditto is not an issue because {{pkmn2|wild}} Mew cannot be legitimately encountered.
{{main|Celebi Egg glitch}}
 
In {{game|Crystal}}, this bug only affects {{m|Sketch}} because {{m|Mirror Move}} will fail against {{m|Transform}}.
===Ditto assumption===
In [[Generation I]] and {{gen|II}}, any {{OBP|Pokémon|species}} that uses {{m|Transform}} is regarded as a {{p|Ditto}} in its new form; this means that if the {{player}} catches a {{p|Mew}} or a [[glitch Pokémon]] which has used the move Transform or a Pokémon which has used Transform via {{m|Mirror Move}}, instead they will obtain a Ditto.
Mew turning into Ditto is not an issue because {{pkmn2|wild}} Mew cannot be legitimately encountered. With the overhaul of the mechanics in [[Generation III]], wild Mew are able to legitimately encountered.
 
====Dragon Fang effect====
In {{game|Crystal}} this glitch is only avaible using the move {{m|Sketch}}, because {{m|Mirror Move}} will fail against {{m|Transform}}.
The [[Dragon Scale]] boosts the power of {{type|Dragon}} moves rather than the [[Dragon Fang]].
 
====Exp. Share formula====
Nonetheless, the [[glitch]] is also no longer a concern because it too was fixed in Generation III.
A {{OBP|Pokémon|species}} with the same [[original Trainer]] as the player that is sent into {{pkmn|battle}} with an {{DL|Experience-affecting item|Exp. Share}} [[Held item|held]] will gain 50% of the [[experience]] twice, which, due to rounding, may not equal 100%.
 
===Dragon=Experience Fang glitchamount====
A {{OBP|Pokémon|species}} that gains an amount of experience consisting of five digits will not have the number displayed correctly but this is only possible with an [[outsider Pokémon]] holding a {{DL|Experience-affecting item|Lucky Egg}} used at the [[Trainer House]]. The lowest [[level]] required for achieving such feat is 82 for Pokémon with an experience yield of 255, and the lowest experience yield with which this is feasible with is 208.
Due to a bug, the [[Dragon Scale]] boosts the power of {{type|Dragon}} moves rather than the [[Dragon Fang]].
 
This glitch was fixed in {{g|Stadium 2}}.
 
===Exp. Share formula error===
A {{OBP|Pokémon|species}} with the same [[original Trainer]] as the {{player}} that is sent into {{pkmn|battle}} with an {{DL|Experience-affecting item|Exp. Share}} [[Held item|held]] will gain 50% of the [[experience]] twice, which, due to rounding, may not equal 100%.
 
===Experience amount oversight===
A {{OBP|Pokémon|species}} that gains an amount of experience consisting of five digits will not have the number displayed correctly. Furthermore, such scenario is only possible in the [[Trainer House]]. The lowest [[level]] required for achieving such feat is 82 for Pokémon with an experience yield of 255, and the lowest experience yield with which this is feasible with is 208. Performing the [[glitch]] also requires an [[outsider Pokémon]] with a {{DL|Experience-affecting item|Lucky Egg}}.
 
{{YouTubeVid|o54VjpAEoO8|Dukstless|Glitch}}
 
====Experience underflow====
{{main|Experience#Experience underflow glitch}}
In [[Generation I]] and {{gen|II}}, [[levelLevel]] 1 {{OBP|Pokémon|species}} using the "medium-slow" growth algorithm will jump from level 1 to level 100 after gaining a low amount of experience points (less than 54 if the total experience is 0).
 
{{YouTubeVid|SXH8u0plHrE|TTEchidna|Glitch}}
 
====HP animationbar oversightanimation====
In [[Generation II]], aA Pokémon whosewhich {{stat|HP}} is greater that 49 will deplete the HP bar at a slower rate than intended when taking damage. Due to an issue with the order of the code within the game, a value that would help to set a delay that was partially dependent on the maximum HP of the Pokémon instead sets always sets a delay that does not change with different HP values. This results in extra delays in the animation updating and prolongs the animation of the bar dropping. A Pokémon with 48 HP or less is not affected as each HP is equal to one or more pixels of the HP bar, thus skipping any delay.

A Pokémon with 48 HP or less is not affected as each HP is equal to one or more pixels of the HP bar, thus skipping any delay.
===Interregional Teleport quirk===
If the player travels to either [[Kanto]] or [[Johto]] in the [[S.S. Aqua]] and then {{m|teleport}}s, he or she will be taken to either the {{ci|Vermilion}} or {{ci|Olivine}} Pokémon Center as opposed to the last [[Pokémon Center]] they used in either [[region]]. This does not occur with the [[Magnet Train]]. If the player loses a {{pkmn|battle}} during their trip, they will be sent to their cabin instead.
 
{{YouTubeVid|SE-BfsFgZVM|Crystal_|Glitch}}
In {{game|HeartGold and SoulSilver|s}}, teleporting after travelling in either Magnet Train or S.S. Aqua behaves properly by returning the player to the last Pokémon Center used. This also applies to lost battles during the trip.
 
====Leveling past 100====
{{YouTubeVid|Va3pzlujwE4|channel/SM|Johto|Kanto}}
If a {{OBP|Pokémon|species}} is obtained at a [[level]] above 100 (101-254), it can be leveled up with {{DL|Vitamin|Rare Candy|Rare Candies}} up to level 255. If a Rare Candy is fed to a level 255 Pokémon, its level will reset to 0. If a Pokémon above level 100 levels up due to [[experience]], its level will be reset to 100.
 
===Legendary=Park beastBall crygraphics distortioncorruption====
If the {{DL|Poké Ball|Sport Ball|Park Ball}} is used from the Ball pocket of the {{player}}'s [[Bag]] on a [[wild Pokémon]], the game will not reload the graphics on the battle screen, causing a temporary glitch in which part of both the Bag and {{pkmn|battle}} screens mix up until the Pokémon catching animation is over, at which point the game will show the battle screen being reloaded.
When the {{player}} checks {{p|Entei}}'s [[Pokédex]] entry, plays its [[cry]], and then immediately switches to either {{p|Suicune}}'s or {{p|Raikou}}'s entries, their cry will be distorted.
 
===Leveling=Present past 100damage====
{{main|Present (move)#Generation II}}
In [[Generation I]] and {{gen|II}}, if a {{OBP|Pokémon|species}} is obtained at a [[level]] above 100 (101–254), it can be leveled up with {{DL|Vitamin|Rare Candy|Rare Candies}} up to level 255. If a Rare Candy is fed to a level 255 Pokémon, its level will reset to 0. If a Pokémon above level 100 levels up due to [[experience]], its level will be reset to 100.
In {{game|Gold and Silver|s}}, the [[move]] {{m|Present}} has a damage formula of its own. This causes the [[level]], {{stat|Attack}}, and {{stat|Defense}} variables of the regular damage formula to be replaced. Thus, the move deals unusually large or small amounts of damage, depending on the {{OBP|Pokémon|species}}.
 
In {{game|Crystal}}, this bug was fixed for regular battles by having Present use the standard damage formula. The old formula from Gold and Silver is still used during link battles to preserve backwards compatibility.
===Park Ball graphics corruption===
If the {{DL|Poké Ball|Sport Ball|Park Ball}} is used from the Ball pocket of the {{player}}'s [[Bag]] on a [[wild Pokémon]], the game will not reload the graphics on the battle screen, causing a temporary glitch in which part of both the Bag and {{pkmn|battle}} screens mix up until the Pokémon catching animation is over, at which point the game will show the battle screen being reloaded.
 
===Pokémon Storage System cloning===
{{main|Cloning glitches#Storage system method}}
 
====Shiny switchTransform glitchswitch====
If a {{m|Transform|transformed}} Pokémon defeats a Trainer's Pokémon and the player switches it out to a [[Shiny Pokémon]] when prompted to, the transformed Pokémon will have a Shiny pallette while being switched. This does not happen if player switches Pokémon normally.
 
{{YouTubeVid|VbPRiHBNh-M|BrightcynderPhase2|Normal}}
 
====Sketch glitches====
{{main|Sketch glitch}}
 
===Trade=Thick cloningClub effect====
If a {{p|Marowak}} with an {{stat|Attack}} stat equal or higher than 256 uses {{m|Swords Dance}} while holding a {{DL|Stat-enhancing item|Thick Club}}, its Attack will be reduced by 1024 (minimum 1) during [[damage]] calculation only. This happens as a consequence of an oversight that causes the temporary Attack boost from {{DL|Stat-enhancing item|Thick Club}} to ignore the [[stat]] cap of 999 unlike other stat modifiers. During damage calculation, both the attacker's (Special) Attack stat and the defender's (Special) Defense stat are modded by 256, and, prior to that, if either is higher than 255, both are temporarily divided by 4. Thus, stats that are equal or higher than 1024 (256×4) will be treated wrongly.
{{main|Cloning glitches#Trading method}}
 
In {{game|Crystal}}, this bug was fixed for regular battles but still occurs during link battles to preserve backwards compatibility.
 
This behavior also applies to {{p|Pikachu}} holding {{DL|Stat-enhancing item|Light Ball}} and to {{p|Ditto}} holding {{DL|Stat-enhancing item|Metal Powder}}. However, these Pokémon need to receive boosts from a Pokémon that knows {{m|Baton Pass}} in order to be able to reach a stat of at least 1024.
 
====Trainer Counter/Mirror Coat damage oversight====
In {{pkmn|Trainer}} {{pkmn|battle}}s only, if the player uses a healing item or a [[Poké Ball]] during the same turn as the opponent's {{m|Counter}} or {{m|Mirror Coat}}, their [[damage]] will be of at least 4 {{stat|HP}}, twice the minimum standard damage for neutral moves (2 HP).

{{main|Time Capsule exploit}}
====Shiny Ditto DV manipulation====
 
In Generation I, if a {{OBP|Pokémon|species}} uses the [[move]] {{m|Transform}} while already transformed, it will retain the {{IV|DV}}s of the Pokémon it transformed into after being {{pkmn2|caught}}. Due to {{Shiny|Shininess}} being determined by DVs in Generation II, this allows the player to make a {{pkmn2|wild}} Ditto Shiny by having it use Transform while already transformed; accomplishing this is possible by either having a Shiny Pokémon that knows Transform ({{p|Mew}}, certain [[glitch Pokémon]], or another Ditto) or by teaching a Shiny Pokémon the move {{m|Mimic}}, then having the wild Ditto use Mimic on the move Transform. The end result is that the Ditto will be Shiny in the Generation II game.
===Shiny Ditto DV manipulation===
The Shiny Ditto glitch requires a game from both [[Generation I]] and {{gen|II}} but it only has an effect on a Generation II game. In Generation I, if a {{OBP|Pokémon|species}} uses the [[move]] {{m|Transform}} while already transformed, it will retain the {{IV|DV}}s of the Pokémon it transformed into after being {{pkmn2|caught}}. Due to {{Shiny|Shininess}} being determined by DVs in Generation II, this allows the {{player}} to make a {{pkmn2|wild}} Ditto Shiny by having it use Transform while already transformed; accomplishing this is possible by either having a Shiny Pokémon that knows Transform ({{p|Mew}}, certain [[glitch Pokémon]], or another Ditto) or by teaching a Shiny Pokémon the move {{m|Mimic}}, then having the wild Ditto use Mimic on the move Transform. The end result is that the Ditto will be Shiny in the Generation II game.
 
{{YouTubeVid|8Lb5pq0y6h8|v0id19|Normal}}
 
====Trade evolution learnset oversight====
{{cat|Generation I Pokémon}} that {{DL|Methods of evolution|Evolution via trading|evolve by trading}} can be taught {{DL|List of glitch moves|glitch moves}} through this [[glitch]]. This can be achieved by [[Trade|trading]] such {{OBP|Pokémon|species}} from a Generation I game to a Generation II game at a [[level]] where its [[Evolution|evolved]] form will learn a [[move]] not present in Generation I. Trading the Pokémon back to the Generation I game will cause the move to become a glitch move.
 
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}}.
 
===Other===
=={{pkmn|Stadium 2}}==
===Infinite=Celebi continuesEgg glitch====
{{main|Celebi Egg glitch}}
This is a glitch that can be performed in [[Pokémon Stadium 2]] with any [[Stadium Cup]]. It does not work in the original {{eng|Pokémon Stadium}}. If there is a previously suspended game and the player is playing the [[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.
 
====Interregional Teleport quirk====
If the player travels to either [[Kanto]] or [[Johto]] in the [[S.S. Aqua]] and then {{m|teleport}}s, he or she will be taken to either the {{ci|Vermilion}} or {{ci|Olivine}} Pokémon Center as opposed to the last [[Pokémon Center]] they used in either [[region]]. This does not occur with the [[Magnet Train]]. If the player loses a {{pkmn|battle}} during their trip, they will be sent to their cabin instead.
 
{{YouTubeVid|Va3pzlujwE4|channel/SM|Johto|Kanto}}
 
====Legendary beast cry distortion====
When the player checks {{p|Entei}}'s [[Pokédex]] entry, plays its [[cry]], and then immediately switches to either {{p|Suicune}}'s or {{p|Raikou}}'s entries, their cry will be distorted.
 
====Pokémon cloning====
{{main|Cloning glitches#Storage system method}}
{{main|Cloning glitches#Trading method}}
 
==Stadium 2==
{{g|Stadium 2}} fixed the following bugs from {{game2|Gold|Silver|Crystal}}:
 
* [[#Dragon Fang effect]]
* [[#Present damage]]
* [[#Thick Club effect]]
 
===Infinite continues===
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.
 
===Pokédex data oversightlocalization===
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 Japanese version.
