Like previous major releases, especially those that set a new generation, Pokémon Black and White went through multiple development stages, many of which included several elements that were eventually dropped or revised before the games' release. Some of these components can still be found within their internal data.
The sprite used in the starter selection screen for Tepig is different in some early videos. The prototype sprite has a more triangular hind foot, with only one being visible on the sprite, and slightly different shading. Also, the silhouettes of the unselected starters are lighter compared to the final.
Early VS sprites for Hilbert and Cheren can be seen in an early video which was broadcasted on Pokémon Sunday. Whilst Cheren's VS sprite had a minor alteration with where his eyes are looking, Hilbert's sprite received a complete overhaul. An early VS sprite for Bianca, lacking her Xtransceiver, was shown in the early video footage that came with an issue of Dengeki Nintendo DS.
In Excadrill's first appearance in a promotional video, its stripes were mirrored. However, this was not long-lived, as it was changed to its current appearance in the next video.

Some retailers in the United Kingdom (specifically GAME and Gamestation) used pre-release box art using the name Alleos for the region as opposed to its final English name, Unova. This name was also used at pre-release and post-release demo events in the United Kingdom.
In several pre-release screenshots and video footage, Castelia City's texture is noticeably different from the final version, with at least four different variations seen before the final release.

Pre-release screenshots of Chargestone Cave show rocks lying around the cave to be of a different shape and having a darker tone with less glow compared to the final version.
On an early screenshot of within Skyarrow Bridge, a female Backpacker can be seen. This Backpacker was replaced by an Ace Trainer in the final release. However, in Pokémon Black 2 and White 2, exactly the same spot is occupied by a Backpacker, just like in the screenshot. In addition, two pre-release screeshots of Skyarrow Bridge depict a slightly different skyline of Castelia City.
Since the engine that powers the games is improved upon that of the Generation IV games, all items from Generation IV, including Poké Balls, key items and unused items, are present in the internal data, with the exception of HM07 and HM08, which are now blank space "?" items. However, most of these items are unobtainable. Other leftover items, like the God Stone, are specific to Pokémon Black and White and can be likewise obtained through modification of the saved game or cheating.

Several lines of unused weather effect text appear within the internal data of Black, White, Black 2, and White 2. Notably, quotes for fog exist within the text, implying that fog functionality was planned to exist in Black and White. While the final game does include foggy locations, such as Route 15, the fog weather condition does not appear in battles.
