An attempt to recreate the classic Need for Speed Games (1-6), unpacking their original data files into a modern scratch built engine. Extremely early in development, current features include:

  • Fully working NFS3, NFS2, NFS2SE, NFS3 PS1, NFS4 track load
  • Explore TR02b! (if you have NFS_3_PS1 folder filled with the ISO contents)
  • Drive the car with WASD, Reset the car with 'R'
  • "Hermite Curve camera" tick box and untick car cam to flythrough track. Unselect both to have a 'free camera', moveable with WASD and viewpoint change by holding right mouse button, move faster by holding "Shift" key.
  • Select car and track from installed Need for Speeds using menu bar (your mileage may vary, major bug related to car load for non high-stakes)
  • Select Car models (Low LOD, Med LOD, Misc parts) in Debug Menu, by expanding "Car Models" dropdown and playing with checkboxes
  • Set Draw Distance by unchecking NBData and adjusting slider (Neighbour data only available for NFS3/NFS4).
  • For NFS3 tracks, change between 'Classic Graphics' and a unfinished slightly more dynamic implementation.
  • Go to free camera, and expand the "Engine Entity" dialog box on an NFS3 track, to adjust lighting parameters for lights after targeting them with the cursor and * clicking. This will affect the colour of the track in non classic graphics mode. Adjust TrackModel Specular Damper and Reflectivity similarly from Debug Menu.
  • Similarly, click the car to tweak physics parameters in real time in the "Engine Entity" dialog, and view data from the car.
  • Pan and zoom around the car with mouse wheel and LMB/RMB in "Car Cam" mode (ensure Hermite Curve cam is unchecked)
  • Set Sky Colour
  • View what the Physics Engine sees with "Bullet Debug View" checkbox.
  • Enable primitive AI with a checkbox in the debug menu, and watch the car drive itself (with great difficulty)

What is ONFS about anyway / What was and is planned?

  • Reverse engineering NFS1-6 PC and PSX (maybe other systems as well)
  • Reading original assets - tracks, cars, images, etc...
  • Game engine for some gameplay with any track and car
  • AI generated by neural learning
  • Music loader
  • Custom(izable) menu
  • Importing tool to easily import CD or iso (maybe even from internet)
  • Customizable music sets (oh look new album from Spacetime Miscalculation from Rom Di Prisco)
  • GUI and console tools built into OpenNFS:
    • Music decoder (encoder)
    • qfs/fsh (de)compiler
    • Video demuxer
    • Car/TrackModel exporter
  • TrackModel Editor and others

Current Loadable Assets

Below is a table better describing the current level of asset load into OpenNFS:

Game Cars Tracks Music
NFS5 PC 40%
NFS4 PC 90% 90%
NFS4 PS1 50%
NFS3 PC 100% 100% 95%
NFS3 PS1 40% 90% 95%
NFS2 SE 90% 90%
NFS2 PC 90% 90%
NFS2 PS1 90% 10%



OpenNFS does not bundle any EA intellectual property. A copy of the original games must be provided to OpenNFS in order to function, instructions for this are available on the release page.

For development builds on CI:

All versions (Windows/Mac/Linux) are built on VSTS, but the current build artifacts only contain the OpenNFS.exe. To use these builds, it is recommended to download a Github Release from the 'Releases' page, and replace the OpenNFS exe with that produced by CI. You will most likely also need to update the 'shaders' directory, using the latest available from Git. I will alter my CI scripts soon to produce zips that can be ran without these extra steps.

Trello Development Board

Check out what I'm working on by looking at the task board here:


The CMake files are currently configured to detect external libraries from within the 'lib' folder at the same level as 'src', just do a 'git submodule update --recursive --remote' to get them.

  • GLEW 2.1.0
  • GLFW 3.2.1
  • GLM 0.9.9-a2
  • Bullet3
  • Boost


Massive thanks to Denis Auroux, Vitaly 'Necromancer', EdasX, Ian Brownm, Jesper Juul-Mortensen and Arushan for their work on reverse engineering various NFS formats.
