ABOUT
SourDex is an unofficial, fan-made companion site for Pokémon Sour Crystal. It's not made or maintained by SoupPotato or the Sour Crystal team — it's a side project that pulls data live from the official repository and documentation to keep this dex and patcher in sync automatically.
This site doesn't host, sell, or distribute any Pokémon ROM. The patcher applies the official Sour Crystal patch (fetched live from SoupPotato's GitHub) to a ROM you already own — nothing ever gets uploaded anywhere.

About the hack
A custom Pokémon game based on the Pokémon Crystal disassembly. Its goal isn't to change the original game, but build upon it — bug fixes, graphical tweaks, and quality-of-life changes, with features visually altered to make better use of the GBC's hardware.
