Black & White Continued
Music speed glitch
When the player uses Dig or an Escape Rope while cycling (cycling music must be playing) or surfing while below the first floor in Wellspring Cave, Chargestone Cave or Challenger's Cave and travels to Pinwheel Forest, Moor of Icirrus or Desert Resort, the music will play with a lower pitch and tempo, as if the player was in an underground floor. Reentering the affected area will revert the music back to normal, as will surfing or using the bicycle.
Mystery Gift Card Album cry glitch
If the player has a Wonder Card that contains a Pokémon on the next page to the one they are currently on, moves the cursor to "Exit" and taps the screen, the cry of the first card on that page will be heard.
Nacrene Gym bookcase glitch
After the bookcase in Nacrene Gym has been moved to reveal the secret stairs, it is still possible to read the book on the bookshelf from the stepladder. If the player stands on the stepladder, saves, then resets, upon resuming it is possible to read the book as if the bookcase had not moved. It is possible to do this until the player leaves the room.
Nimbasa Gym Trainer glitch
In Japanese versions of Pokémon Black and White, if the player loses to Lady Colette in Nimbasa Gym while directly facing her when encountered, this glitch will occur. When the player comes back in she will be standing on the same spot and will battle the player. After she is defeated, she still remains on the tracks of the roller coaster, and can be passed through while riding the roller coaster to Elesa.

Opelucid Gym air walk glitch
On the sloping part of the path before the first dragon's tail in Opelucid Gym, the two tiles directly up and down can be walked on, leaving the player walking on the air.
Opelucid Gym pedestal glitch
In front of both "certified Trainers" pedestals in the Opelucid Gym is an empty tile that cannot be walked on. This tile is interacted with rather than the pedestal itself, and acts just like it. The pedestal cannot be walked on, however.
Opelucid Gym shadowed tiles glitch
Yet another glitch in Opelucid Gym is that all of the tiles behind the Gym Leader can't be walked on.
Relic Castle glitch
On B3F of the Relic Castle near the drop point from the hole closest to the correct drop point to B2F there is a non-solid wall tile. It is on the wall one tile to the left of the wall directly to the south of this drop point.
Sitrus Berry glitch
If a Pokémon holding a Sitrus Berry hurts itself from confusion and reaches under half of its max HP through the damage, then its Sitrus Berry will not activate until another form of damage is dealt.
Shed Shell glitch
Sometimes in in-game battles, if the player's lead Pokémon holds a Shed Shell, it will be unable to switch out. This glitch does not occur in link battles.
Sky Drop glitch
This glitch can only occur in Double and Triple Battles. It is activated when Gravity is used while two Pokémon are in the semi-invulnerable state after Sky Drop is used. Gravity will bring the user of Sky Drop down while the target will be stuck in the semi-invulnerable state, unable to move until it is knocked out.
Text speed glitch
An old woman in Driftveil City talks one text speed slower than the selected text speed. This is due to her missing a large section of code, and is not intentional.
TM67 Retaliate glitch
In Japanese versions of Pokémon Black and White, TM67 (Retaliate) appears as a Dark-type TM, despite the move being Normal-type.
Trick Room glitch
If a Pokémon has an effective speed greater than 1809, it will ignore the effects of Trick Room and act before slower Pokémon.
Variable scoring glitch
This glitch only works in cities and towns that can be flown or teleported to with variable scoring dependent on the player's location in the area: Nacrene City (accordion player), Icirrus City (clapping group walking in a circle), and Opelucid City (harmonica player). If the player is in the area that the variable scoring is active, and flies or teleports to that same city or town, the variable scoring will be active until the music is changed, regardless of the player's location within the city or town. Likewise, if the player is in an area where the variable score is not active and flies or teleports to that city or town, the variable score will not activate until the music is changed.
Walking Trainer glitch
When blocking the path of certain Trainers who walk in a loop, if their path is blocked at a corner so that they cannot change direction, they will continue walking in the direction they were slowly and without turning, so as to appear to be walking into nothing but behaving as if they are walking into a wall.
Wellspring Cave glitch
When the B button is pressed on the 1st Basement floor of the Wellspring Cave the NPC's will start moving at different speeds depending on the Trainer. With some difficulty, this allows players to avoid all of the Trainers on the floor.
In all Generation V games
TM94 Rock Smash glitch
In Black, White, Black 2, and White 2, TM94 (Rock Smash) appears as a Rock-type TM, despite the move being Fighting-type.
