Proto:Pokémon HeartGold and SoulSilver

This page details one or more prototype versions of Pokémon HeartGold and SoulSilver.

This page or section details content from the October 2024 Game Freak Leak. Check the October 2024 Game Freak Leak category for more pages also sourced from this material.

This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

To do: There's 61 Prototypes that can be built. This should be split up into 2007, 2008, early 2009, mid 2009 and late 2009 if need be. There's some milestone builds. Should we document these over the rest?

Music

Many of the earliest builds use the same instruments as Pokémon Diamond and Pearl. Additionally, the gs_sound_data.sdat file from VER20080930 (dated 2008-Sep-30 as well) has replaced the DP instruments with newer ones, making the remaining/unused Sinnoh music sound different (or plain wrong in some cases).
