This article is incomplete.

Reason: Missing information

The engine that powers Pokémon Black 2 and White 2, like Pokémon Gold and Silver and their Generation IV remakes, is directly based on that of its prequels. Despite this, they still go through similar stages of development as all other main series games.

Post-release findings

Pokéstar Studios

There are alternate colored sprites for several Pokéstar Studios opponents in the games' code, which are presumably Shiny sprites. However, it isn't possible to encounter the Shiny sprites in the final release.

Items

Every key item's sprite since Generation III, including the ones not in Generation IV such as the Fame Checker, exist in the games' data. Furthermore, item data for all key items since Pokémon Diamond and Pearl is still present.

Pokémon World Tournament

In the internal text file for the Pokémon World Tournament, there are two complete sets of unused text strings for Hilbert and Hilda, the player characters of Pokémon Black and White. These strings are located between the ones for Volkner and the Driftveil Tournament participants.^[1] This indicates that they were intended to appear as opponents on an unidentified tournament; in the final release, with the exception of multiplayer interactions with either Black or White, neither character appears at all but are frequently referred to by other characters.

Unlike the Memory Link references to the player character in the final release, their names are permanently set as Hilbert and Hilda. Both sets of text are identical, with the exception of swapping the respective names as necessary.

Quotes

The moments in the player's adventure at which the quotes are labeled to originate from are conjecture, based on the ordering consistency of the text strings used and by associating them with the remaining text strings for the Pokémon World Tournament used in the regular gameplay.
