MTR-PGR4

MissingTheRecompilation: Project Gotham Racing 4

A Windows PC recompilation of Project Gotham Racing 4, with a graphical launcher, 720p/1440p rendering, 30/60 FPS options, optional motion blur, and the garage's Geometry Wars game. Built with ReXGlue, following the work of beatrixzy's PGR4-Recomp.

Getting started

1. Download the Windows x64 ZIP from Releases and extract the whole ZIP to a writable folder.
2. Extract your own PGR4 disc image as described below. No game files are included.
3. Open MTR-PGR4.exe, choose the extracted game folder with Browse, and pick your resolution, frame rate, fullscreen and motion blur settings.
4. Click Play. Settings are remembered. Geometry Wars can be launched from the launcher or the in-game garage; its Exit to PGR4 option is supported.

The release includes the runtime and renderer: you do not need to install ReXGlue to play. Windows x64, a Direct3D 12-capable graphics card and .NET Framework 4.8 are required. A controller is recommended, particularly for garage walking. The launcher starts the games directly; PowerShell is not needed to play.

Extracting your ISO

The tool used for this project is XBOX360 ISO Extract 0.6 by somski. Its release thread and download and the ConsoleMods extraction guide describe the same utility (XBOX360 ISO Extract.exe).

1. Open the extractor and set the source directory containing your PGR4 ISO.
2. Set a separate destination directory for the extracted files. Keep deletion of the original ISO disabled if you want to retain your backup.
3. Rescan, select PGR4 in the extraction list, and click Go. Wait for completion.
4. In MTR-PGR4, browse to the resulting game folder—not the ISO itself or its parent folder. That folder should contain default.xex, Game, UI, and the other extracted directories. Geometry Wars also needs gw.xex and gw.

Use your own legally obtained game dump. Preserve the complete extraction; moving only the XEX files is insufficient. The game folder can be on another drive.

Known bugs

• Vibration and engine noise can disappear at high RPM ranges.
• Small frame-rate hitches remain in certain maps.
• Some shadows have minor visual problems, especially in car interiors.
• Liveries sometimes differ from their menu previews. The left side can show a small corrupted area near the front wheel arch.

Saves and settings

Your saves are created locally; the release contains no pre-existing saves. PGR4 uses runtime/userdata, Geometry Wars uses runtime/geometry-wars/userdata, and launcher settings are stored in runtime/launcher-settings.json. Keep these when updating an existing installation.

Source and credits

See BUILDING.md to build both games and the launcher. Developers need their own extracted PGR4 files and ReXGlue v0.10.0 with the included changes; the build guide explains how to obtain and apply them.

THIRD_PARTY.md records upstream code provenance and credits, including beatrixzy, Tera/Creesic, ReXGlue, Xenia and the graphics/audio libraries. New MTR-PGR4 code is available under the MIT license. Third-party components keep their own licenses; these permissions do not cover the original game's assets.
