# Hybrid: matching reconstruction of the Japanese PlayStation executable

> Hybrid reconstructs the Japanese 5.877 PlayStation game's P69.EXE as linked assembly, C and classified data. The author reports an exact hash match for the rebuilt executable, while only a small portion is matching C; the repository also documents recovered MUF material and LEV level structures.

## Requirements & limits

- **Prerequisites:** A user-supplied Japanese 5.877 P69.EXE is required for setup and exact rebuild checks.
- **Prerequisites:** The project requires its documented MIPS build tools and compiler workflow for matching C functions.
- **Limits:** Most matched code remains assembly; matching C covers a small portion of the payload.
- **License:** The LICENSE file grants MIT terms to original project tooling and documentation; reconstructed game code retains separate rights.
