Monster Rancher Recompiled

This release candidate uses PSXRecomp and the shared recomp-ui launcher. You must supply your own SLUS-00568 game disc and SCPH-5502/5552 Europe BIOS. The package contains no game disc, retail BIOS, generated retail game code, or saved game.

Setup

1. Extract the complete setup ZIP into a writable folder.
2. Start Monster_Rancher_Recompiled (.exe on Windows).
3. Select your CUE file and the required BIOS in the setup wizard.
4. Run Generate & rebuild and wait for the game to start.

On Windows, the setup wizard can download the portable build tools. On Linux and macOS, install CMake, Ninja, Python 3, and a C/C++ compiler first. Keep the CUE and all files it references together. The BIOS must be 524288 bytes with SHA-256 1faaa18fa820a0225e488d9f086296b8e6c46df739666093987ff7d8fd352c09.

Candidate status

Version 0.1.0 is being prepared for September 7, 2026. Package setup and gameplay acceptance are pending; native build checks do not establish gameplay support. The exact source and dependency identities are in project-manifest.toml. See feasibility and validation for the tested scope.
