About

A static recompilation of Mega Man Legends 2 built on psxrecomp and recomp-ui, set up as a kit where you supply your own SLES-03556 (Europe) disc image and your own SCPH-5552 (Europe) BIOS dump. First-run setup generates and compiles the game on your machine. The README calls it a version 0.1.0 release candidate and does not claim full-game completion, audio fidelity or multiplayer.

Getting started

Download the setup ZIP for your platform from the releases, extract it, start Mega_Man_Legends_2, and in the setup wizard select the Redump CUE (or a CHD of the same dump) and your BIOS file. Then run Generate & rebuild; the first run takes several minutes. A diagnostic mode can be turned on if the game crashes or freezes.

Known issues & limitations

Full-game completion, audio fidelity, and multiplayer are not claimed.
Linux and macOS setup and gameplay have not been verified.
A Track 01-only BIN fails verification; use the CUE or a CHD made from the full dump so every audio track is mounted.
Runtime snapshots from older builds are not qualified as compatible.
The disc has audio tracks, so you must select the CUE or a CHD of the full dump; a Track 01-only BIN fails verification.

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).

Features

The setup creates both a normal and a diagnostic build.
You can run the title standalone or manage it with Retro Launcher.
Ordinary memory-card saves are preserved across updates.

How to install

Download the setup ZIP for your platform from Releases and extract it into a writable folder.
Start Mega_Man_Legends_2; on Windows, use the .exe.
In the setup wizard, select your Redump CUE or a CHD made from the same dump, along with your BIOS file.
Choose Generate & rebuild and wait for the game to start; the first run takes several minutes to compile.
