Forza Motorsport 4 Recompiled (fm4-recomp)

Verdict: you can play Forza Motorsport 4 on a Windows PC, but only as an experimental alpha. Forza Motorsport 4 Recompiled (fm4-recomp) by Alexandros Mandravillis (Alexbeav on GitHub) is an unofficial project that turns the Xbox 360 game into a native 64-bit Windows program. Races, saves and the early career work; performance and some graphics are still rough. It ships no game files, so this page has no download or play link. We only describe it.

Status on 2026-10-17: working, alpha. The latest version is 0.1.0-alpha.2, published on 2026-10-15.

What it is

The Xbox 360 runs on a PowerPC processor, so its games cannot run on a PC as they are. An emulator such as Xenia solves this by imitating the console while you play. A static recompilation works differently: the game’s code is translated into native x86-64 PC code once, ahead of time, and compiled into a normal Windows program. Nothing is translated on the fly while you race.

fm4-recomp does this with ReXGlue, an open-source Xbox 360 recompilation toolchain, using the author’s own fork of its SDK. A runtime stands in for the Xbox system functions the game expects, and graphics run through Direct3D 12.

Current status

According to the README and the project’s status page, on the developer’s tested Windows system the game can:

• boot to the main menu and load a profile;
• complete races and save career progress, including achievements and driver levels;
• progress through the Amateur and Clubman tiers into Sportsman;
• install the four content packages from Disc 2.

What does not work yet, or is not confirmed:

• the career beyond the Sportsman tier has not been validated;
• car thumbnails can come out blank on a fresh profile;
• the safe graphics settings are slow: stutter and about 30 FPS in heavy scenes, and a stable 60 FPS is not reached;
• higher internal resolutions and faster timing settings cause visual corruption;
• online features are outside the tested scope, and Linux and macOS versions are only open requests.

What you need

• Game files from your own copy of Forza Motorsport 4. The README validates only the Europe Game of the Year edition, Disc 1. Disc 2 is optional.
• A 64-bit Windows PC with a Direct3D 12 graphics card. The README gives no minimum CPU or GPU.
• Building from source also needs developer tools (PowerShell 7, Git, CMake, Ninja and Clang).

Who made it

• Alexandros Mandravillis (Alexbeav) wrote fm4-recomp and maintains it.
• ReXGlue provides the recompiler and runtime; the project credits code in it derived from Xenia, the Xbox 360 emulator.
• A separate repository with the same name, GabrielCRadu/fm4-recomp, says it is based on Pinyon Shift, arcanite24’s Forza Horizon recompilation. Its README describes only an initial boot milestone, and it has no releases. Alexbeav’s repository does not mention Pinyon Shift, so a direct link between the two projects is not confirmed.

Is it safe and legal?

• It is an unofficial fan project, not affiliated with Microsoft, Xbox or Turn 10 Studios.
• The repository contains no game data; you supply files from a copy you own.
• Unlike Pinyon Shift, which builds the game on your PC, alpha.2 also offers a ready-built Windows program. Whether Microsoft objects to that is not known; no takedown had been filed when we checked.
• Use only the GitHub repository. We do not link builds.

Not working?

Check the status page in the repository first: the known issues above are expected. Crashes can be reported in the project’s GitHub issues; one crash-on-start report was open on 2026-10-17.
