Pokémon Black and White

The 5th generation of Pokémon games starts with this pair of games on the DS. Set in the far-off Unova region (based on New York City!), they introduce a full set of new Pokémon; not a single older Pokémon makes an appearance before the Elite Four except for Pikachu. Yes, you read that right. It also has more of an emphasis on the storyline of the game.

Key items from Generation IV
All the key items from Pokémon Diamond and Pearl through to Pokémon HeartGold and SoulSilver still exist in this game. This includes the unused key items from Diamond/Pearl.

Poké Balls not used in Black and White
These are in the game for compatibility with Pokémon caught in the previous games. These include Safari Balls and Bug-Catching Contest/Apricorn Balls from HeartGold/SoulSilver, among others. If hacked into the bag, most of them can't actually be used.

On a related note, Dream Balls, when hacked into the Bag outside of the Entree Forest, work as normal Pokéballs. Cherish Balls (used for distributions) that are hacked into the Bag work the same way.

God Stone
A gray-ish recolor of the Light Stone/Dark Stone sprite, with a stubby description.

Wonder Launcher power-ups
There are several items used only in the Wonder Launcher multiplayer battle mode. These items are temporary power-ups for Pokémon which are more potent than typical ones. If hacked into the bag they can't actually be used.

Poké Toy
Key Item version exists.

Lock Capsule
This unreleased event item from HeartGold and SoulSilver was intended to be transferred to Black and White. It was never distributed, but it works perfectly if hacked into Black and White. Taking it to Mr. Lock in Castelia City enables you to open it, revealing TM95, which contains Snarl. Note that trying to use the Relocator to port it from HeartGold and SoulSilver will not work–the Relocator will not recognize the Lock Capsule. This is most likely because it was not programmed to recognize the item, as the event was cancelled.

TM95
Seeing as its planned distribution method never happened, TM95 isn't normally obtainable in Black and White. Until the sequels, the only way to get Snarl was to breed it from an event Zoroark or a Smeargle that has Sketched it from it.

Unused Hidden Abilities
In the Generation V games, it is possible to find Pokémon with special "hidden Abilities". However, some Pokémon couldn't be encountered with hidden Abilities through any legitimate means, rendering the hidden Abilities unused in normal gameplay.

The new breeding mechanics of the Generation VI games gave Gothita, Rufflet, and Klink their previously-unused hidden Abilities.

Larvesta and Volcarona can now be found with their hidden Ability in the Generation VI games.

Also of note is that Litwick, Lampent, and Chandelure's hidden Ability in the Generation VI games changed from Shadow Tag to Infiltrator. These Pokémon can now be found in the Generation VI games with Infiltrator. Zapdos's hidden Ability was changed to Static in Generation VI, and it can be seen with this Ability in the Battle Maison. However, it still remains unobtainable.

Unused Graphics
Among the few uncompressed graphics are logos for Pokemon Diamond and Pearl, probably because Black and White were built on top of those games. There are also graphics for the underground mining minigame, which is not present in B/W.

Unused Fonts and Text Entry
There are a complete set of Japanese and English fonts; they look fairly simple and unpolished, and the hiragana font seems to have been freehanded with a mouse.

They can each be combined with a single palette and tilemap to form the following screens, presumably used to input text:

These graphics and tilemaps are present in both the Japanese, North American, and European releases.

Unused Sound Test Graphics
There are also unused graphics for what looks like either one hell of a sound test, or a whole sound mixer:



They have a single palette and two tilemaps:



These graphics are present in the Japanese, North American, and European releases.

Unused Camera Controls
There are graphics for an unused camera controller present.



Unused Wonder Launcher Item Sprites


In the files for the Wonder Launcher item sprites are three textures that resemble the items Max Ether, Elixir and Max Elixir.

Unused 3D Models
There are unused 3D models for both Dialga and Palkia from the title screen of Diamond & Pearl.

Anti-Piracy
If the game detects the player is playing on a flash card or emulator, the game will freeze at random points and the player's Pokémon will be unable to gain experience points.

Nacrene Museum
A different version of Nacrene Museum exists in the ROM of the game. It contains vastly different textures and modified movement permissions, as well as additional polygons that shouldn't be where they are. The version of the map in the video is a result of file swapping, so all the scripts of the original Nacrene Museum are used. The state of the room at the time suggests that this copy of the room could have been a damaged version of the room (Given events from early on in the game), or that it could have had debugging features at one time. As well, this room shows that at one point, there was only one entry point to the Gymnasium, as opposed to 3. This map also exists in Pokémon Black 2 and White 2. J4oqGqrGzLs

Differences:
 * Completely different textures that aren't used anywhere else in the game
 * Some polygons are missing and there are some additional polygons
 * There are no artifacts on the shelves, and signs to denote what the item on the table is are replaced with flower pots
 * There is a soda machine and a sign on the wall that are not present in the final
 * The doorway leading to the gym has the movement permissions for a doorway that is three spaces wide, but only uses one space
 * There is a random, unused polygon
 * There is a doormat at the entrance to the building
 * There are incorrect movement permissions

P2 Laboratory
If a Walk Through Walls code is used to move south of the boundaries of the P2 Laboratory, a completely textureless map can be found. It appears to be a completely different map altogether, not meant for the Lab itself. Structures used as placeholders for some models are visible, and several tables and trash cans are present. Note that trash cans are sometimes used as placeholders as well. Southward, an area which seems to be meant for water, such as for a lake or oceanfront view, can be seen. It is unknown what this area would have been used for. This area also exists in Black 2 and White 2.

Unused Sound/Music
Deep inside the game's music files the following VOs appear with their respective names:

SEQ_SE_DDEMO_01

SEQ_SE_DDEMO_02A

SEQ_SE_DDEMO_02B

SEQ_SE_DDEMO_03

Kyurem Alternate Forme Placeholder Data
There exists placeholder data for an alternate form of Kyurem in Black and White. There is a table within the game's coding that specifies the number of Formes/forms a Pokémon has. Pokémon that have no alternate forms are listed with the number 0. Pokémon with alternate forms are listed with a number corresponding to the number of forms they have. For example, Pikachu has the number 0, while Deoxys has the number 4. (Note that Genesect has 5, based on its normal form and the four Drives, but the Pokédex does not list them as separate Formes.) There is one exception to this: Kyurem is the only Pokémon listed with the number 1. This number is meant to be a placeholder, meaning that at least one alternate Forme is in development.

This was previously seen in the coding of Pokémon Diamond and Pearl, in which Rotom, Giratina, and Shaymin had the number 1 listed.

Kyurem ended up with two new Formes, Black Kyurem and White Kyurem, in Pokémon Black 2 and White 2. Tornadus, Thunderus, Landorus, and Keldeo, which all gained new Formes in the sequels, are listed with the number 0, suggesting that the alternate Formes for these Pokémon were not in development until later.

Unobtainable Shiny Pokémon
For the sake of consistency, every Pokémon in every Pokémon game is given a Shiny variant. Most Shiny Pokémon have been obtainable through random chance encounters or event distributions, including most Legendary Pokémon. However, a few Pokémon cannot be obtained in this form without hacking, and as a consequence, normal players would never be able to see their Shiny coloration.


 * Reshiram, Zekrom - These Legendary Pokémon are encountered via fixed in-game battles. However, their probability of being Shiny is locked at 0.


 * Victini - Also encountered in battle, but during a distribution-based event. Like Reshiram and Zekrom, Victini's Shiny probability is locked at 0.


 * Keldeo, Meloetta - These Mythical Pokémon were only obtainable through special distributions via Mystery Gift. Pokémon obtained from Mystery Gift cannot be Shiny unless distributed as such, and no distributions of these Pokemon in their Shiny forms were ever planned. The Shiny variant of Genesect, the third Mythical Pokémon of Generation V, was distributed in some Asian countries following the premiere of the 16th Pokémon movie.

Poison Touch
In the Japanese version of the games, a Pokémon with the Ability Poison Touch has a 20% chance of poisoning the opposing Pokémon when it uses a contact-making move. This was changed to 30% in the international versions.
