Crystal Challenge Patch

16-Bit Challenge Run Patch

Latest update: 28th June 2026 (v0.1)

This patch combines all the pre-existing Pokémon Crystal Patches for Challenge Run and Nuzlocke playthroughs, adding a wide range of quality-of-life options. It is regularly updated based on community feedback.

This patch is a 16-bit conversion of Pokémon Crystal and is in early development, there will be bugs. I do not know what the bugs will be yet!
