The end result is that the Ditto will be Shiny in the Generation II game.

Revision as of 18:51, 21 December 2013

This is a list of glitches that occur in the Generation II core series Pokémon games.

Gold and Silver

NOTE: The following glitches affect all versions of Japanese Pokémon Gold and Silver (1.0 and 1.1) unless noted otherwise.

Present damage miscalculation

Main article: Present (move)#Generation II

In Pokémon Gold and Silver, the move Present has a damage formula of its own due to a glitch. This causes the level, Attack, and Defense variables of the regular damage formula to be replaced. Thus, the move deals unusually large or small amounts of damage, depending on the Pokémon.

This glitch was fixed in Pokémon Stadium 2 and in Pokémon Crystal.

Trainer House corruption

Main article: Trainer House glitch
BoEANSprite.png This glitch is in need of research.
Reason: Does it occur in the Japanese and Korean releases? Is it really fixed in Crystal?
You can discuss this on the talk page.

This glitch affects the Trainer in the Trainer House and is caused by corrupted RAM for the save file in Pokémon Gold and Silver.

It was fixed in Pokémon Crystal.

Bug-Catching Contest data copy glitch

Main article: Bug-Catching Contest data copy glitch
BoEANSprite.png This glitch is in need of research.
Reason: Gold/Silver JP V1.0 & V1.1 or just V1.0? Is it present in Gold/Silver KO?
You can discuss this on the talk page.

This glitch is exclusive to the Japanese releases of Pokémon Gold and Silver. When the player flies out of the Bug-Catching Contest while it is taking place, it causes the creation of unstable Pokémon data.

It was fixed in the international releases and in Pokémon Crystal.

Crystal

NOTE: The following glitches affect all versions of English Pokémon Crystal (1.0 and 1.1) unless noted otherwise.

Legendary beast Pokédex cry distortion

BoEANSprite.png This glitch is in need of research.
Reason: Does it also occur in Gold/Silver?
You can discuss this on the talk page.

When the player checks Entei's Pokédex entry, plays its cry, and then immediately switches to either Suicune's or Raikou's entries, their cry will be distorted.

Overworld player sprite miscoloration

This glitch affects the color of the player's overworld sprite, switching it between Ethan's red and Kris' blue palettes. It is caused by creating a save file as either Ethan or Kris, then overwriting it with another save file using the other player character but turning the game off while the new data is being saved. The effect disappears after saving and rebooting the game (note that the old save file will be overwritten).

In all Generation II games

NOTE: The following glitches affect all versions of Japanese Pokémon Gold and Silver (1.0 and 1.1) and of English Pokémon Crystal (1.0 and 1.1) unless noted otherwise.

Celebi Egg glitch

Main article: Celebi Egg glitch

Coin Case glitches

Main article: Coin Case glitches

Ditto assumption

In Generation I and II, any Pokémon that uses Transform is regarded as a Ditto in its new form; this means that if the player catches a Mew or a glitch Pokémon which has used the move Transform or a Pokémon which has used Transform via Mirror Move, instead they will obtain a Ditto.

Mew turning into Ditto is not an issue because wild Mew cannot be legitimately encountered. With the overhaul of the mechanics in Generation III, wild Mew are able to legitimately encountered. Nonetheless, the glitch is also no longer a concern because it too was fixed in Generation III.

Exp. Share formula error

A Pokémon with the same original Trainer as the player that is sent into battle with an Exp. Share held will gain about 50% of the experience (due to rounding) twice, which it will not equal 100%.

Experience underflow

Main article: Experience#Experience underflow glitch

In Generation I and II, level 1 Pokémon 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).

Five-digit experience amount oversight

A Pokémon 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 Lucky Egg.

Leveling past 100

In Generation I and II, if a Pokémon is obtained at a level above 100 (101–254), it can be leveled up with 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.

Love Ball catch rate error

The Love Ball only gains a catch rate of 8× on Pokémon of the same gender and species as the player's Pokémon, rather than on Pokémon of the opposite gender.

Park Ball graphics corruption

If the Park Ball is used from the Ball pocket of the player's Bag on a wild Pokémon, the game will fail to reload the graphics correctly, causing a temporary glitch in which part of both the Bag and battle screens merge until the Park Ball's graphics are cleared.

Pokémon Storage System cloning

Main article: Cloning glitches#Storage system method

Sketch glitches

Main article: Sketch glitch

Thick Club effect error

If a Marowak with a maximized Attack stat (maximum DVs and stat experience in Attack) uses Swords Dance while holding a Thick Club, its Attack will overflow to 8.

This glitch was fixed in Pokémon Stadium 2.

Trade cloning

Main article: Cloning glitches#Trading method

Glitches involving communication with the Generation I games

Johto guard bypassing

Main article: Johto guard glitch

Shiny Ditto DV manipulation

The Shiny Ditto glitch requires a game from both Generation I and II but it only has an effect on a Generation II game. In Generation I, if a Pokémon uses the move Transform while already transformed, it will retain the DVs of the Pokémon it transformed into after being caught. Due to Shininess being determined by DVs in Generation II, this allows the player to make a wild Ditto Shiny by having it use Transform while already transformed; accomplishing this is possible by either having a Shiny Pokémon that knows Transform (Mew, certain glitch Pokémon, or another Ditto) or by teaching a Shiny Pokémon the move 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.

Trade evolution learnset oversight

Generation I Pokémon that evolve by trading can be taught glitch moves through this glitch. This can be achieved by trading such Pokémon from a Generation I game to a Generation II game at a level where its 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 Graveler from Pokémon Red to Pokémon Gold will cause the Graveler to evolve into Golem. Since it is at level 34, it will learn 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 Generation II move, so it will become TM05.
