Pokémon Diamond and Pearl beta

Before their release, went through multiple stages of development, many of which included several things eventually dropped during that period. Some remnants of this data can still be found within the internal data of the games.
==Pre-release==
===Sprites===
, , , and all have had prototype sprites from various pre-release pictures and videos, but these sprites have been removed from the final release. Munchlax's sprite seems to be a duplicate from the Munchlax sprite in Pokémon Dash. The Cherrim prototype sprite was shown in an early Japanese commercial. It was surprisingly like the final sprite, only with the left leg up instead. Pokémon.com published prototype sprites during their run up to the release of . Scizor's sprite, as shown in one of the prototype screenshots, depicted the same pose as its final sprite, albeit considerably larger, and using its color palette from the Generation III games rather than the darker palette from the final sprite.
There are also leftover sprites of both the and Team Galactic . Despite the fact that the Ken Sugimori artworks didn't change for the final release, the overworld sprites were different. The rival's sprite featured a slightly different hair style while the Team Galactic Grunts had darker blue hair, somewhat similar in color to Saturn's hair.

===Maps===
Official pre-release screenshots depicted different designs of certain maps. Two screenshots are of Jubilife City and show the Pokémon Center and the Poké Mart in different spots than the final release. Another screenshot depicted with an unfinished look for water, sand and rocks. The last screenshot depicts , where some early s can be seen.

===Camera===
Unlike in the final release, which forces a parallel perspective inside most buildings, the three-dimensional perspective view used in the overworld was apparently intended for use in all buildings. Several objects inside of the buildings themselves, through modification of the game's engine camera to force it into its perspective view, have been revealed to actually be fully 3D models, such as tables.
In , buildings that are intended to be viewed in the forced perspective camera lack side walls, only having the back one, while buildings whose interior design is carried over from have side walls fully modeled, such as inside of Pokémon Centers. This modeling of the side walls actually causes a graphical glitch, due to sprites being seen to pass through the walls on their edges, as well as on their shadows.
===Pokétch===
In multiple pre-release screenshots, an early design for the Pokétch was shown. It had a smaller app changing button and more of the device on-screen. Also, the Digital Clock application was shown without a at the bottom-left corner of the screen.
===Font===
The font used for the text as seen in the pre-release screenshots of the Japanese versions is very similar to the font used in the Japanese versions of the Generation V games.
===Unused Models===
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 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.
==Post-release==
===Maps===
An alternate map for Spear Pillar was discovered. It is similar to the regular Spear Pillar, but the entrance to Mt. Coronet is missing. It is speculated that the Mystery Zone found at the is a possible prototype map.
An earlier version of Great Marsh contained in the game files plays the Mystery Zone music and contains no NPCs, Pokémon, or events. Strangely, the Great Marsh is listed as Pastoria City instead; implying that Great Marsh may have been intended to be a city at one point. The internal file name for this map is D06R0101.
Two unfinished floors for exist in the finished game. They are the third and fourth floor. One of the floors plays the Gym music and has an NPC that gives the player a Focus Band. The stairs are glitched and do not let the player go down to the next floor.
Sunyshore City has an unused map with two NPCs who cannot be interacted with and the map's entrance has no defined coordinates making exiting the map impossible without cheating.
There are five unused areas in Oreburgh City, however; only one of the unused maps contains any NPCs. The two NPCs speak normally. The internal file name for this map is C03R0603
Mystery Zone with ID 0x019A appears to be an unused record mixing room. It plays Pokémon Center (Day) during daytime and Pokémon Center (Night) during nighttime.
===Marsh tile===
The marsh tile in which the player can battle is only used in the Great Marsh (where normal battles cannot occur), yet it has in-battle effects programmed for it. Specifically, will change the user's type to , will turn into , and will use the animation of and may lower the target's Speed by 1 stage.
===Roaming Darkrai===
Within the coding of the game, there is data for a roaming Darkrai left within the game but with no way to be activated without the use of cheating devices.
===Music===
* A remix of Title Screen: Main Theme from can be found in the internal data with a label of SEQ_TEST_TITLE. It can be inferred that it was added during the initial stages of development as either a test track (as per the filename) or as placeholder until Opening Movie was made and added in.
* An unused remix of Battle! (Gym Leader), that was most likely intended to be used for the against Palmer can also be found among the internal files under the name SEQ_BA_TOWER.
* Music played while in the Mystery Zone is a variant of Route 206 (Day). Its filename is an ambiguous SEQ_DUMMY, but it has been speculated that it could be an earlier version of the theme that ended up being associated with placeholder areas without their own music (such as the Mystery Zone).
* While tweaking and given the is present in an area that the games identify as Jubilife City, a variant of Jubilife City (Day) is played. It is presumed that this theme was an unfinished version of the ordinary theme.
* An alternate version of the Lake Crater music (labeled SEQ_EV_LEGEND) goes entirely unused but is still present within the game.
* 's music files are labeled and placed next to town themes (SEQ_TOWN06_D for the Day version and SEQ_TOWN06_N for the night version), implying that Route 225's music may have been meant for a town at one point.
* An unused version of the Wild Pokémon victory music goes unused with a file name of SEQ_SLOT, meaning it was likely meant to be used for the Veilstone Game Corner slot machines.
* Several files, named SEQ_D_ICE, SEQ_D_UNKNOWN, SEQ_POKEPARK and SEQ_BF_FACT play an identical two-second jingle, the ascending C major scale, on a piano-like instrument. All of these go unused in the final games and are likely jingles that went unused in the final game and replaced with placeholders that were removed during development.
* A remix of the capture fanfare is present, likely meant as a placeholder.
* Early versions of 's Day and Night music are present (labelled SEQ_ROAD_BZD_D and SEQ_ROAD_BZD_N). Interestingly, the Night and Day versions seem to be reversed, as the "Night" version plays slightly faster and contains the notes that distinguish the Day version from the Night version in the final game.
* Three unused songs associated with the unreleased Azure Flute event that were meant to play when the flute is used at Spear Pillar, when walking to the event area, and when the battle with occurs.
===Items===
* S.S. Ticket, the ticket for granting entry on the luxury liner S.S. Anne. It is likely a carryover from .
* Contest Pass, which would allow entry into . However, allow entry without a pass. Furthermore, the item was only used in , having been unused since .
* Magma Stone, a mystical item that would have been used at Stark Mountain. Albeit used by NPCs during the 's adventure, it is not obtainable by them. It is possible it would have something to do with the event. This hypothesis would later be confirmed in Pokémon Black 2 and White 2 as or obtains the item at , which allows Heatran to be summoned at Reversal Mountain.
* Red Chain, which is a creation by the lake guardians that would be used to awaken or . Cyrus himself actually uses the item during the plot, and it's possible that the Team Galactic event at the Spear Pillar was initially meant to be activated by the .
* , an unusable about using Nintendo Wi-Fi Connection. It's possible that this was removed since these guidelines were included in the instruction book of the games.
* , an unusable item that holds up to ten Seals, but was replaced with the Seal Case.
* , a sack for holding treasures from the Underground. It was replaced with a unique menu for the Underground.
===Sprites===
Back sprites of and , presumably from one of the earliest stages of development, were found. Shellos' sprite is pink, like its , and seems to combine the western variation's head with the 's body, while Gastrodon's sprite is brown and looks like its , but with more rock-like protrusions on its body. Before the release of , this was also considered by some fans to be another "unofficial confirmation" of Pokémon Gold and Silver remakes, since their Pokédex data states that its colors and shapes differ from region to region. However, this proved not to be true due to the similarities to the final forms, and the fact that there are no front sprites for either of the prototype forms. Additionally, there are no known forms of Shellos or Gastrodon that are exclusive to HeartGold and SoulSilver.
The internal data also contains different back sprites for , , , , , , , , , , and – both regular and forms. Sprites of a , and the 18 shiny variants of Arceus are also available. Also unused is an early gray-scale version of 's front sprite, although it is facing the left instead of the right.
Alternate sprites for the , , and , as well as a sprite for the class, which consists of a male and a female , were also discovered.
There is also an early status sprite within the in-battle move effect graphics data set showing sprites for a duckling looking left and looking right.
