# Galaxian³: Project Dragoon — PlayStation matching decompilation

> cannon-seed reconstructs C source for Galaxian³: Project Dragoon on PlayStation across Japanese and European boot executables and game payloads. Its build pipeline splits target executables, compiles candidates with a pinned toolchain, and compares rebuilt images with retail SHA-1 hashes. The repository also retains assembly for nonmatching functions.
