Pokémon Diamond and Pearl were the first of the fourth generation of Pokémon games, and the first core-series games on the Nintendo DS. They brought back and standardized old features such as day/night cycles (from Pokémon Gold and Silver), wireless online battles and trades (from Japanese Pokémon Crystal), and the categorization of moves based on the individual moves rather than on their types (from Pokémon XD: Gale of Darkness; known among fans as the physical/special split). Of course, there's also new Pokémon and other new mechanics as well.

Enough debugging text in here to swim in. I'm not even kidding.
| Unused Graphics|
Unfinished graphics galore.
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.
Quite a few Key Items remain in the code. If hacked into your inventory, they have no use, but they all have item descriptions.
"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.
"The pass required for entering Pokémon Contests. It has a drawing of an award ribbon on it."
"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.
"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 hung around forever and ever in newer games...until it was finally made obtainable in Pokémon Black 2 and White 2.
"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 was later released in Platinum, it was never released for Diamond and Pearl. This item would allow you to access the locked house in Canalave City, which sends you to New Moon Island, and subsequently to catch Darkrai.
"A letter from Prof. Oak. Written in it is a request for you to go to Rt. 224."
While this event item was later 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.
"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 a hold of it.
"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.
"A tiny bag that can hold ten Seals for decorating Poké Balls."
Apparently dumped in favor of the Seal Case.
"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.
Add more info from the Platinum page's version of this section.
Early Great Marsh (0x00DF)
A version of the Great Marsh without wild Pokémon, people, or any events. The game names this area "Pastoria City", and the Mystery Zone music plays (SEQ_DUMMY). Its internal name is "D06R0101".
Jubilife Condominiums 3rd and 4th Floors
Jubilife Condominiums has two extra floors. One of them has Gym music, and a Focus Band given to you by an NPC.
Unused Sunyshore House
Sunyshore City has an unused map with two NPCs who cannot be interacted with by the player. It appears to have undefined map coordinates regarding its exit point.
Oreburgh Area (0x003F)
One of the five unused areas in Oreburgh City. This one has two guys with normal dialogue strings. Its internal filename is "C03R0603".
Record Corner (0x019A)
In Ruby, Sapphire, and Emerald, the Record Corner is the Pokémon Center 2F room where players can mix records. The unused equivalent in Diamond, Pearl, and Platinum was scrapped and the record mixing features were moved to the Union Room.
Some of these are early versions of already-existing tracks, such as SEQ_SLOT. Compare them to the final tracks here.
Route 225's tracks are displayed as "SEQ_TOWN06_D" and SEQ_TOWN06_N" in the files, indicating that they may have been intended to be used as music for a town.
An unused remix of the Eterna City/Celestic Town music, which doesn't seem to fit the ancient atmosphere of the two areas. Its file name indicates that it might have been for Celestic Town at night.
An alternate version of the Wild Pokémon Victory music. Its name implies that it could have been used for winning money at the slot machines in the Veilstone Game Corner.
An alternate version of the Lake Crater music.
A remix of the Pokémon FireRed and LeafGreen capture fanfare.
SEQ_D_ICE/SEQ_D_UNKNOWN/SEQ_POKEPARK/SEQ_BF_FACT (004F / 0051 / 0052 / 0063)
An unused track that plays a series of ascending notes.
MIDI HEX 0003 is the title screen music from Pokemon Ruby/Sapphire/Emerald.
MIDI HEX 0089 is an unused mix of the Gym Leader battle theme which was meant to be used for the Palmer battle in the Battle Tower, before being replaced by Cynthia's theme. In particular, the instrumentation at the beginning is louder in this version.
A very early version of the Route 206 theme, used for the Mystery Zone. It is MIDI HEX 0000.
SEQ_ROAD_BZB_D and SEQ_ROAD_BZB_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.
An unused option for a Pedometer of sorts can be found in the text for the main menu. A pedometer in the form of the Pokéwalker accessory would later be used in tandem with HeartGold and SoulSilver, which do have an option for it on their main menu. Additionally, a pedometer application that counts the player’s steps in-game was included in the Pokétch. Whether this feature came into being before or after this menu option is unknown.
Jubilife City Gym
⋯⋯になりたい ただの おるすばん
Jubilife City's Gym Leader!
...But I'm just the humble caretaker.
Text for an NPC pretending to be Jubilife City's Gym Leader exists in the Japanese versions of the game, providing additional evidence that there was to be a Gym in Jubilife City. The text bank that holds this line in the international copies is simply emptied out.
Hall of Origin and Azure Flute
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 because the event was thought to be too confusing for players, Arceus was distributed directly as an event Pokémon instead.
Interestingly, it seems that an Azure Flute distribution hadn't been 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 three 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. The filename may refer to Arceus's name from earlier in development, "Ausu". Again, it calls back to a song motif that is still used in the game, particularly the ambient sounds that play during the beginning of the intro and on the title screen.
The theme which plays when battling 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, albeit in a slightly different form due to the different soundfonts.
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. Shiny Arceus was later made available as a distribution via serial code in Omega Ruby and Alpha Sapphire with the purchase of tickets to the 18th Pokémon movie.
Unused Arceus Form
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.
Unused Roaming Darkrai
In the game's files, there is data for an unused encounter with a roaming Darkrai at Lvl. 40. It is released on the map if one executes script command 0x21C with its parameter set to 0x2. The existence of this battle suggests that Darkrai was originally planned to be caught in the same fashion as its counterpart Cresselia. This data also remains in Pokémon Platinum.
Unused Wild Held Item Data
Some Pokémon, when found in the wild, have a chance of holding an item. This held item data also exists for some Pokémon which cannot be caught in the wild in the final game, however, rendering these assignments unused.

A house model that isn't used anywhere in Jubilife City.
There's a file that has a similar filename to this model that may be holding animation data (/data/fs_kanban.nsbca). Investigate this, and attempt to load the animation data in-game.
An unused sign model that is very similar to the ones placed outside shops in Pokémon HeartGold and SoulSilver, but is independent of the shop model. It was probably intended to be placed in front of or next to Pokémarts, but was changed during development.
An unused model of a flat sign with "P.C" written on it, which likely stands for "Pokémon Center". It was probably intended to be placed in front of Pokémon Centers, but was changed during development.
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.
The following is every tileset ripped from the game. Pinpoint unused tilesets from this. http://i84.photobucket.com/albums/k13/Cyhunt/DPRipping/Allfiles.png
In the texture files of an unused Poké Mart model, there is text which isn't even used in the model.
Unused Texture Set
Within the game's texture files, there is a set of textures that go unused, and ultimately display unused graphics. However, these textures were displayed in some pre-release screenshots of the game, so it was likely that these textures were placeholders and were intended to be removed. The textures can be displayed in-game by reloading the graphics while in the Mystery Zone and then returning to the overworld. Interestingly, the dirt path tiles seem to have been shifted around in development, and the water tiles appear to animate incorrectly. The textures are identified as texture 0 within the game's coding.
Route 217 Snow Texture Set
In the textures that are used on Route 217 (identified as texture 14 in the game's coding), there are a few unused textures, one of which has what seems to be a placeholder for the bicycle stands that appear in Eterna City and Oreburgh City.
In that same set of textures, there is also unused textures for the lakes and their respective edges. However, only the center of the lake has textures; the edges do not appear to have any textures in the designated texture file. They may have been removed during development, or the developers may have made the main lake texture, but never finished the rest of the still lake texture in favor of creating moving water for Lake Acuity, which uses the same texture set.
Additionally, it has an unused path texture, a differently-colored version of the loamy soil for berries, and a slightly brighter edge around the puddles. The loamy soil texture would have gone unused mostly due to the fact that no berries would have grown in the locations where its texture would have been used, but it was never removed. They may have also been copy/pasted around during development to save time and then left in.
Unused Pokémon Back Sprites
Compare them to the final versions.
Many of these are carryovers from earlier builds of the game. Notably, Bronzor's back sprite is an earlier version of its front sprite, and Jirachi's back sprite here is cropped.
|Pokémon||Sprite||Shiny||Sprite Female||Shiny Female||Sprite 2|
Unused Trainer Sprites
In the game's files, there are three alternate Trainer battle sprites, as well as a sprite meant for the "Sis and Bro" trainer class (first introduced in Ruby and Sapphire), which was ultimately scrapped here and didn't reappear until Omega Ruby and Alpha Sapphire.
Sis and Bro
Unused Overworld Sprites
There are some sprites in the game still that match styles used in pre-release screenshots. Rip n' upload these.
A generic male NPC sprite that's never used in the game.
Unused Large NPC
A different version of the larger NPC's sprite. The unused version looks more stretched-out, making the sprite seem...even larger.
Unused Rival Sprites
Unused Pokétch Apps
Screenshots of the unused apps.
The "Stopwatch" and "Alarm Clock" apps for the Pokétch are unused. They are assumed to have been planned for event distribution like how the "Matchup Checker" app was distributed at Pokémon Center stores in Japan, but they were never distributed in any event.
Unused Pokétch Graphics
See if there's any residual code left over that could make use of any of these graphics in the game's overlays.
A series of Pokétch-themed buttons that represent various menu-related activities remain in the ROM. Such an interface was eventually used in Pokémon HeartGold and SoulSilver, and was probably removed from the selection of apps because it would've meant having to switch apps just to be able to access basic game functions, such as adjusting options or saving, as well as because of the Pokétch not being immediately available. This axed app may have been the inspiration for the various touch-screen interfaces that future games used. Also worthy of note is that there is only one bag design. In the final game, the male protagonist uses a backpack (as pictured), while the female protagonist uses a shoulder bag. Also, half of the icons here (the Pokédex, Bag, and Save icons) were redrawn when put into the Start menu.
Two graphics for large Pokétch switches also exist. These switches are not used on any of the 23 used or 2 unused Pokétch apps.
An unused script is present in Floaroma Town. It contains a dialogue with Cyrus, who you meet later in the final release. There are triggers that match the check for an X value between 170-172, and Cyrus is also present in the NPC data of Floaroma Town. Based on these facts, it can be stated that the player was originally supposed to meet Cyrus in Floaroma Town. References to the text exist in all languages, but the Japanese version has additional messages, for which scripts may also be present. The video shows the reconstructed script.

Japanese ROM Size
The header in the ROMs of the initial release of the Japanese versions specifies a size of 128 MB, but revision 5 decreased it to 64 MB.
In the Japanese versions, the title screen instructs players to "PUSH START BUTTON", but the localizations instead state "PRESS START".
Unlike Ruby, Sapphire, FireRed, LeafGreen, and Emerald, the Western localizations of Diamond, Pearl, Platinum, HeartGold, and SoulSilver use a different Japanese font for regular text as opposed to the one from the Japanese versions.
Black, White, Black 2, and White 2 instead use a Japanese font that is reminiscent of the one seen in some of Diamond and Pearl's pre-release Japanese footage.
Registeel uses a different pose in all non-English European releases of the game, as its original pose could be misinterpreted as a Nazi salute. This change was later applied to all versions of Platinum and retained for HeartGold and SoulSilver. It appears that the sprite was redrawn from scratch rather than edited, given the different shading.
The Matchup Checker app for the Pokétch was distributed to Japanese players to celebrate the American release of Diamond and Pearl, and was later made available in-game in Platinum. Additionally, players of Diamond, Pearl, and Platinum could obtain a Lucario Doll from the Lucario Wakuwaku Fair event.
In revisions 0 and 5 of the Japanese versions, there are two issues which were officially acknowledged by Nintendo on October 24, 2006.
- Aaron's room at the Pokémon League allows the player to surf and enter the void.
- Returning to the second floor of the Pokémon League after using the Union Room causes the player to get stuck in a wall.
Nintendo proposed a solution to affected players who got stuck but had not saved the game yet. For other players, Nintendo recommended using the ダイヤモンド・パール修復プログラム Diamond & Pearl Recovery Program that was released on October 27, 2006 and could be downloaded from any DS Station, later 3DS Station, up to February 2018 or from the Wii's Nintendo Channel during its lifetime. Alternatively, they could mail in their cartridges for repair until February 2018.
Moves that suppress or change Abilities are Skill Swap, Worry Seed, Gastro Acid, Role Play, and Transform. Verify whether the bug in question happens with all of them or only some.
The following bugs are all exclusive to the Japanese versions.
- A Pokémon transforming and then having its held item stolen in battle will lead to both Pokémon retaining the item after battle, provided the transformed Pokémon does not faint. This can be used in Double Battles to easily duplicate items.
- Successfully using Transform through Mimic and then fainting will cause the user to permanently keep the moveset of the Pokémon it transformed into.
- A holder of a Choice item who then uses Pursuit on the same turn that the target switches out can use a different move on the next turn, even though that would normally be prevented by the Choice item.
- The Attack and Speed drops caused by the Slow Start Ability are retained even if the Ability is removed.
By the time Nintendo and The Pokémon Company opened their South Korean subsidiaries in 2006, Game Freak was finalizing Diamond and Pearl. A Korean release did not occur until 2008, and it has some limitations, such as items like the Manaphy Egg being unobtainable due to inherent incompatibilities and the unavailability of the required spin-off games. However, because at least Japanese Ruby and Sapphire were released in South Korea, Pal Park accepts all languages of Ruby, Sapphire, FireRed, LeafGreen, and Emerald, unlike the Japanese and Western versions. The transferred Pokémon are treated as nicknamed due to the language mismatch, behavior that is not exclusive to the Korean versions.
Since gambling is illegal in South Korea, the slot machines of the Veilstone Game Corner were replaced with Game Machines that drop 5 to 20 Coins every day, and multiple texts in the casino were altered. These changes were later ported to European versions of Platinum, which also edited Looker's dialogue accordingly. Note that the player can still buy Coins, and that the Game Machines are said to break if Lemonade or Soda Pop is spilled on them.
The red color of some female-gendered strings like Original Trainer (OT) names was replaced with pink for cultural reasons, as names written in red are believed to bring misfortune or even death.
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, while 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, indicating that at least one alternate Forme is in development.
Wild Encounter Rate Changes
In source code leaks from 2020, certain dates have been found to be able to modify the encounter rates of Pokémon found in the overworld by walking. This adds directly to the base rate of an encounter with Pokémon by walking on that map (or of tile types on that map, such as grass and water) each step. The value cannot increase beyond 100%. The dates that modify these values correspond to holidays and events; some of these increase the rate of finding wild encounters, while others decrease it instead.
