NFS Most Wanted (2005) — Unity rebuild

A from-scratch rebuild of Need for Speed: Most Wanted (2005, PC) in Unity, written by reverse-engineering the original speed.exe (v1.3) function by function. It runs on your own installed copy of the game: Rockport, the cars, the menus, the career scripts, the sounds and the cutscenes are read from the game folder while it runs.

No game content is in this repository — no textures, models, audio, music, video, data files or executable. You need your own copy of Need for Speed: Most Wanted (PC).

Website: https://magicibrar.github.io/nfsmw-unity/ (what works, how it was built, setup and modding).

Status

• 98 % of the game's code ported (effective, measured over speed.exe's 2.35 MB of game code; 80 % ported function for function, the rest partial, nothing missing). See NFSMW_RE/coverage/coverage.md.
• A playable offline career from the press-start screen to the Blacklist: races, pursuits, the safehouse, car lot, customization, the Challenge Series, split screen and LAN.
• 9 automated play tests and a 55-shot screenshot tour pass on every build.

Details per feature: NFSMWUnity/README.md. How each file format and system was reversed: NFSMW_RE/REPORT.md and the specs in NFSMW_RE/specs.

Point it at your game

The rebuild needs the installed game folder: the one that contains GLOBAL, TRACKS, CARS, FRONTEND and speed.exe. It looks for it in this order:

1. -gameRoot "D:\Games\Need for Speed Most Wanted" on the command line
2. a file named gameroot.txt next to the player exe (or next to Assets in the editor) holding that path
3. the NFSMW_ROOT environment variable
4. the retail default, C:\Program Files (x86)\EA GAMES\Need for Speed Most Wanted

The rebuild targets the v1.3 data (the patched retail game). It only reads the folder; it never writes to it.

Build and run

1. Install Unity 6000.4.2f1 (Unity Hub) and, for the tools, the .NET 8 SDK.
2. Clone this repository and open NFSMWUnity in Unity.
3. Create NFSMWUnity/gameroot.txt with your game path (see above).
4. Open Assets/Scenes/FreeRoam.unity and press Play, or build with NFSMW > Build Windows Player (or ./batch.sh NFSMWBuild.BuildWindows build from Git Bash). Put a gameroot.txt next to the built NFSMWUnity.exe too.

Controls, split screen and LAN are described in NFSMWUnity/README.md.

Modding

Export the game's textures (PNG) and models (OBJ), edit them, and drop the results into a Mods folder; the rebuild loads them instead of the originals. Your game files are never changed. See MODDING.md.
