About

An unofficial native recompilation of the Xbox 360 version of UFC Undisputed 3 for PC, built on the ReXGlue SDK. It is not emulation: the game executable is translated from PowerPC to C++ and compiled as a native PC program. Only Windows x64 is tested, and the native renderer is described as having its foundation in place but scene rendering not implemented.

How it differs from the original

Because the game advances one simulation step per vblank, the README says 60 Hz is the correct speed and the default: at 144 Hz the simulation would run 2.4x faster than on console. Render supersampling is locked at 1x because a saturated GPU lowers the speed of the game rather than the frame rate.

Getting started

The release ships a ready executable, so nothing needs compiling. Run the launcher, point it at the ISO of your own legally obtained disc or at an already-extracted folder, and click Extract and play. The launcher checks the title ID and tells you which game it found if you pick a different one.

Known issues & limitations

The native renderer does not draw the scene yet; the emulated GPU still draws every frame.
A saturated GPU slows the game, so render supersampling is locked at 1x.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Xbox 360 version).

You must provide files from your own legally obtained Xbox 360 copy.
Only Windows x64 has been tested; Linux, macOS, and ARM64 are untested.

Features

The game runs as a native PC program rather than through emulation.
The launcher can adjust resolution, quality presets, language, and controls.
The final image receives contrast-adaptive sharpening and the settings menu has a blurred, darkened backdrop.

How to install

Download and extract the release, run UFC3 Launcher.exe, select your disc ISO or extracted folder, then click Extract and play.

Additional notes

Other platforms: The build presets also list Linux, macOS and ARM64, but the README says none of those have been tested.
No retail files: The project does not include retail game files; you must provide files from your own Xbox 360 copy.
