About

Mortal Kombat 4 Recompilation is a static recompilation of Mortal Kombat 4 for modern systems, built on psxrecomp and recomp-ui.

Getting started

You must own the original USA game and supply a disc image matching the exact single-track CUE/BIN identity the package accepts. A legal SCPH-1001 BIOS dump is also required, since OpenBIOS is not supported by this package, and retail BIOS dumps are not redistributed.

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).

You must own the original USA game, SLUS-00605.

Status & roadmap

The ports are developed by a hobbyist with substantial AI assistance, and every change is validated before it ships.

Licensing & legal

Project-owned source, scripts, configuration and documentation use GPL-3.0-only, while PSXRecomp remains under PolyForm Noncommercial 1.0.0 and recomp-ui under MIT.

Additional notes

Validation: No build counts as a public release until its exact package passes every listed validation gate, and boot evidence does not replace a full gameplay test.
