# LittleBigPlanet PSP: a matching decompilation of EBOOT.BIN

> LittleBigPlanet PSP reconstructs code from the game's UCUS98744 disc version 2.00 executable as C and C++. Its checker compiles each source with a recorded compiler profile and compares the resulting function bytes with the original. The author reports 5,020 individually matched functions; a whole-module build of the published proofs has not been measured.

## Requirements & limits

- **Prerequisites:** A personal copy of the game and a locally decrypted PSP_GAME/SYSDIR/EBOOT.BIN are required.
- **Prerequisites:** The documented checking workflow uses WSL and the specified PSP compiler toolchains.
- **Limits:** The author reports 17.9% of public-scope code bytes matched individually; whole-module progress is unmeasured.
- **License:** Project code is GPL-3.0-or-later; bundled third-party code retains its stated terms.
