# Ratchet & Clank: Size Matters — scoped PS2 matching decompilation

> Ratchet & Clank: Size Matters decomp reconstructs source for US and European PS2 boot executables and level modules against retail bytes. The project separates authored C matches from assembly baselines and records accepted placements and compiler evidence for bounded portions of the game.
