# Pokémon Colosseum: continued GameCube matching decompilation

> Pokémon Colosseum continues a GameCube matching decompilation with additional C and data reconstruction, a measured progress ledger, and native Windows build support. It covers the GC6E01 DOL and 25 REL modules. The author reports byte-identical rebuilt outputs using original fallback objects where source reconstruction remains incomplete.
