# Devil Within Co-op: statically recompiling Tekken 5's Devil Within mode

> Devil Within Co-op statically recompiles the Devil Within mode from a user's Tekken 5 USA disc into generated Rust, then runs it through a Rust PS2 runtime and Bevy application. Its pipeline extracts the compressed ELF, exports Ghidra analysis and generates code locally; added hooks provide cooperative play, a mod menu and reconstructed developer menus.
