Do I need the original game files to run Galerians Recompilation?

Yes. The project does not include the original game's assets, so you need your own copy.

Galerians Recompilation

RecompilationActive

The original game's compiled code translated into a native program for a new platform, usually a PC port.

About

A static recompilation of Galerians built on psxrecomp and recomp-ui, packaged as an owned-input setup kit. You supply your own three Galerians (Europe) disc images and an SCPH-5552 (Europe) BIOS dump, and first-run setup generates and compiles the game on your machine. The README calls it a version 0.1.0 release candidate.

Getting started

Download the setup ZIP, extract it into a writable folder, start Galerians, select your three disc images (Redump CUE or CHD) and the BIOS in the setup wizard, then run Generate & rebuild. The first run compiles the game and takes several minutes. Setup starts with Disc 1, and later discs are selected when the game asks for them.

Known issues & limitations

Disc changes during play have not been qualified on the recompiled build; setup and startup were verified with Disc 1.
Native setup and gameplay have not been verified on Linux or macOS.
Full-game completion, audio fidelity, and multiplayer are not claimed.
Runtime snapshots from older builds are not qualified as compatible.
Disc changes during play have not been qualified on the recompiled build; setup and start were verified with Disc 1.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (PlayStation version).

On Linux and macOS, install CMake, Ninja, Python 3, and a C/C++ compiler first.

Features

The title can be run standalone using the release ZIP and built-in Generate & Build flow.

How to install

Download the setup ZIP for your platform from Releases and extract it into a writable folder.
Start Galerians; on Windows, use the .exe.
In the setup wizard, select the three disc images and your BIOS file.
Choose Generate & rebuild and wait several minutes for the first-run compilation and game startup.
Keep each CUE file with every file it references; setup starts with Disc 1, and later discs are selected when requested.

Status & roadmap

The README says the Windows setup package passed automated setup and a headless start check, and a private build was reported playable. Linux and macOS gameplay has not been verified, and full completion, audio fidelity and multiplayer are not claimed.

Additional notes

Diagnostic mode: A diagnostic build is produced during setup and can be switched on to collect a diagnostics zip for bug reports.
