This page details one or more prototype versions of Pokémon Crystal.
Document the prototypes from the German, French, and Italian localizations, as well as the English v1.1 and Australian releases.
On April 24, 2020, a massive leak containing files from the development of Pokémon Gold, Silver, and Crystal was released to the internet. Among these is mostly-complete source code for Crystal, which contains several ROMS relating to the localization of Crystal.
Builds from the English localization are of particular note as many features from the Japanese Crystal were removed or changed in all other versions of the game, and the English localization served as the basis for all other language localizations. Unfortunately, unlike previous games, the source code does not have version control data, so it is not possible to find any Japanese builds.
