This article is a work in progress.
...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

Pokémon Diamond and Pearl were the first Pokemon games in the 4th generation.


Debug Strings
Enough debugging text in here to swim in. I'm not even kidding.
Unused Maps
A LOT of unused maps.
Unused Graphics

Demo Version

The kiosk demo of Pokémon Diamond and Pearl was used in stores prior to the game's release, and contains many differences from the final.

Unused Items

Quite a few Key Items remain in the code. If hacked into your inventory, they have no use, but they all have item descriptions.

Fluffy Tail (0x40)


"An item that attracts Pokémon. Use it to flee from any battle with a wild Pokémon."

Has the same effect as the Poké Doll.

Shoal Salt (0x46)


"Pure salt that was discovered deep inside the Shoal Cave. It is extremely salty."

This item was required in Ruby and Sapphire to make a Shell Bell.

Shoal Shell (0x47)


"A pretty seashell that was found deep inside the Shoal Cave. It is striped in blue and white."

This item was required in Ruby and Sapphire to make a Shell Bell.

Mosaic Mail (0x93)


"Stationery featuring a print of a vivid rainbow pattern. Let a Pokémon hold it for delivery."


Would have been used for an event like the Brick Mail.

Loot Sack (0x1AD)

Pokemon Loot Sack Sprite.png

"A sturdy, spacious bag that is used to carry loot obtained in the coal mine."

Would have been used to carry the items found in the underground. In the final game, the underground menu serves this purpose.

Rule Book (0x1AE)

Pokemon Rule Book Sprite.png

"It lists the rules for holding battles. For linked battles, you may choose which set of rules you wish to use."

Was possibly required at one point to select different battle types in link battles.

Seal Bag (0x1B4)

Pokemon Seal Bag Sprite.png

"A tiny bag that can hold ten Seals for decorating Poké Balls."

Apparently dumped in favor of the Seal Case.

Red Chain (0x1B9)

Bag Red Chain Sprite.png

"A mythical chain that is said to link the legendary Pokémon that created the Sinnoh region."

Cyrus uses this as a part of his ultimate scheme, but the player never gets ahold of it.

Oak's Letter (0x1C4)

Pokemon Oaks Letter Sprite.png

"A letter from Prof. Oak. Written in it is a request for you to go to Rt. 224."

While this event item did get released in Platinum, it was never released for Diamond and Pearl. This item would allow you to access the Flower Paradise and subsequently catch Shaymin.

Member Card (0x1C6)

Pokemon Member Card Sprite.png

"A card needed for entering the inn in Canalave City. Oddly, the last date marked on it was 50 years ago."

While this event item did get released in Platinum, it was never released for Diamond and Pearl. This item would allow you to access the locked house in Canalave City, where sends you to New Moon Island and subsequently catch Darkrai.

Azure Flute (0x1C7)

Pokemon Azure Flute Sprite.png

"A flute that puts out echoing sounds that do not seem to be of this world. It is unknown who made it."

See its own section.

S.S. Ticket (0x1C8)

Pokemon S.S. Ticket Sprite.png

"The ticket required for sailing on the ferry S.S. Anne. It has a drawing of a ship on it."

Every game before this had an S.S. Ticket for some sort of boat.

Contest Pass (0x1C9)

Pokemon Contest Pass Sprite.png

"The pass required for entering Pokémon Contests. It has a drawing of an award ribbon on it."

This was required in Ruby and Sapphire to enter contests, but not in Emerald. Apparently scrapped in this game, too. Returned in the Ruby and Sapphire remakes using the same sprite.

Magma Stone (0x1CA)

Pokemon Magma Stone Sprite.png

"A stone formed when boulders melted in intensely hot magma, then hardened. Magma remains sealed inside."

This item figures into the Stark Mountain events, but is only handled by NPCs. Like all of Generation IV's key items, this hangs around forever and ever in newer games... ...until it's finally obtainable in Pokémon Black 2 and White 2.

Unused Music

To do:
  • Rip [the unused remix] of the FireRed/LeafGreen "successful capture" jingle.
  • There are some duplicates of used tracks.

In the games, there are a few samples of unused music.

SEQ_DUMMY (0000)

There is also the Mystery Zone music, which is a very early version of the Route 206 theme. It is MIDI HEX 0000.


MIDI HEX 0003 is the title screen music from Pokemon Ruby/Sapphire/Emerald. This was likely used for testing purposes when the game was being developed.

SEQ_ROAD_DZB_D and SEQ_ROAD_DZB_N (0020 / 003B)

Two early versions of the Route 205 tunes. Interestingly, the unused Night music is a bit faster than the unused Day music.


The note scale used as a placeholder for several unfinished music.


MIDI HEX 0089 is an unused remix of the Gym Leader battle theme, which was supposed to be used for the Palmer battle in the Battle Tower, before being replaced by Cynthia's theme.

Unused Models

To do:
There is more...


PKMN DPPT dmybox00.png

A placeholder model called dummy box 0. It might have been used as a placeholder until certain models were created.



DP Unused Sign.png

In the games, there is also an unused model that is used for shops. It is very similar to the ones placed outside shops in Pokémon HeartGold and SoulSilver, but is independent of the shop model, and they also don't rotate. Through hacking, these models can be loaded to the game and work perfectly fine, except they don't glow, unlike the Pokémon Mart.

Unused Accessories


One unobtainable accessory and one unobtainable backdrop exist in the game. It is unknown how either of them would have been obtained, though the Comet can be obtained through Pokésav.

Unused Trainer Class

One unused trainer class named Sis and Bro exists in the game. Its ID is 0x2F.

Unreleased Events

Newmoon Island and Member Card

Flower Paradise and Oak's Letter

Hall of Origin and Azure Flute

Pokemon-DP-Hall of origin.png

An event item exists known as the Azure Flute, which was never officially distributed, and can only be obtained through hacking the game. When hacked into your Bag, the Azure Flute can be used at Spear Pillar to warp to another map, the otherwise unused Hall of Origin above Spear Pillar. Atop a glass staircase, on a platform high in the sky, you encounter a level 80 Arceus. It seems this event was the originally planned method of Arceus distribution, but for reasons unknown Arceus was distributed directly as an event Pokémon instead.

Interestingly, it seems that an Azure Flute distribution wasn't ruled out as late as the releases of HeartGold and SoulSilver; those games have a mechanism to allow a Hall of Origin-caught Arceus to return the player to the Sinjoh Ruins and get another one of the trio of Dialga/Palkia/Giratina.

As a consequence of this event remaining unused throughout the entirety of Diamond, Pearl and Platinum's release, all of the assets associated with the Hall of Origin area, including 3 unique pieces of music, are never used in the games:

The melody which plays upon using the Azure Flute. Note the immense similarities to both the "Push Start" sound effect as well as the 6 note jingle which plays on the "Game Freak Presents..." screen.

The "theme" which plays for the Hall of Origin. Again, it sounds extremely similar to a theme already used in the game, particularly the ambiance which plays on the title screen.

The theme which plays when one battles Arceus. While totally unused in the Sinnoh trilogy of games, it was eventually reused for the aforemented Sinjoh Ruins event cutscene in HeartGold and SoulSilver.


Shiny Arceus


For the sake of consistency, every Pokémon in every Pokémon game is given a Shiny variant. Arceus is no exception, having a Shiny palette for each of its 18 forms, including the one not accessible through normal gameplay (see below). However, because the only way to obtain it legitimately was through distributions, the Shiny version of Arceus was left unobtainable through normal means.

Unused Arceus Form

PKMN DPPT Arceus Graphic1.png PKMN DPPT Arceus Graphic2.png
PKMN DPPT Arceus Graphic3.png PKMN DPPT Arceus Graphic4.png
Arceus has an unused form as well! Arceus' type changes to the type of the plate it is holding. However, it also has a ??? form, based on the special ???-type most notably used as the type of the move Curse (up until Generation V). Because there is no plate based on this near-placeholder type, this form is never seen.

Regional changes

Japanese Font

The Western localizations use a different Japanese font for regular text as opposed to the one from the Japanese versions. This also applies to Platinum, HeartGold, and SoulSilver.

This was not the case in the Generation III games, where all releases use the same Japanese font. The Generation V and VI games also did not replace the Japanese font.

Registeel Sprite

In the non-English European versions of Diamond and Pearl, Registeel's sprite was edited because of its arm. The arm's original position is reminiscent of the salute of the Nazis. The sprite change was later applied to all versions of Platinum and retained for HeartGold and SoulSilver.

Pokétch Matchup Checker

In Diamond and Pearl, "Matchup Checker" was obtained from a Japanese only event. It became available in-game in Platinum.

Lucario Doll

PKMN DPPT LucarioDoll.png

In Diamond and Pearl, the Lucario Doll was obtained from a Japanese only event.

Surf glitch

In the Japanese versions, it is possible to surf right through the entrance door in Aaron's room in the Pokémon League. This makes it possible to traverse the entire void, which can lead to useful things (such as capturing the normally event-only Pokémon Darkrai and Shaymin without needing any event), but can also result in the player being stuck forever, especially when saving. This has been fixed in the international versions of the game.

Item cloning

In the Japanese versions, if a Pokémon holding an item uses the move Transform and then has its item stolen in battle, both Pokémon will retain the item after battle provided the transformed Pokémon does not faint. This can be used in double battles to easily duplicate items. This bug too was fixed in the international releases.

Mimic glitch

Another glitch exclusive to the Japanese versions of the game, if a Pokémon uses Transform by way of the move Mimic and then faints after transforming, it will keep the moveset of the Pokémon it transformed into forever.

Ability bugs

The Attack and Speed drop provided by the Slow Start ability is retained in the Japanese versions even if the ability is removed, for example by way of Skill Swap. This was fixed in the international versions.

Rotom, Giratina, and Shaymin Alternate Forme Placeholder Data

There exists placeholder data for alternate forms of Rotom, Giratina, and Shaymin in Diamond and Pearl, suggesting the alternate forms (sometimes referred to as "Formes") featured in Pokémon Platinum were already in development. 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. There are three exceptions to this: Rotom, Giratina, and Shaymin are the only Pokémon listed with the number 1. It seems this number is meant to be a placeholder, meaning that at least one alternate Forme is in development.
