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 were a massive amount of ROM builds from the different localizations of Crystal.
The 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 was where these changes were made.
