PROJECT OVERVIEW
What this effort is rebuilding
Pokémon Crystal is tracked as a matching decompilation. That approach reconstructs readable source while comparing the rebuilt output with the original Game Boy Color program. A reported percentage should be read as the project’s own matching metric—not as a promise that every asset, tool, or gameplay system has been documented.
READING THE SIGNAL
What the progress figure means
The tracked source reports 100% progress. That normally describes the repository’s declared code target; documentation, ports, bug fixes, tooling, and work on other regional versions may continue after that milestone.
PRESERVATION CONTEXT
Why this project is worth following
This work helps document how a Game Boy Color title was structured and built. Following the project can expose platform-specific techniques, compiler behavior, file formats, and engine decisions that are otherwise difficult to study. The repository currently identifies Assembly as its primary language context.
QUICK ANSWERS
About Pokémon Crystal
Is this an official release?
No. Decomp 720 tracks an independent community project maintained by pret. The original game and its assets remain the property of their respective rights holders.
Does the repository include the game?
Usually not. Reverse-engineering projects commonly require contributors or users to supply legally obtained game data. Check the repository’s own setup instructions before building anything.
How does Decomp 720 verify updates?
This page checks the linked public repository no more than once per day. It only replaces the tracked percentage when a clearly labeled, machine-readable or README progress figure is available.
