Original GP4 PC Manual

GP4 retro 2012 MOD - My customization of GP4's original liveries to lightly mimic the 2012, 2013, 2014, 2015, 2016 & 2017 F1 seasons, while staying faithful to Geoff Crammond's original GP4 car shapes and templates within the sim.

Very Simple & Easy Install. The only other (optional) tweak you may possibly wish to do is using Lo2k's Team Editor to adjust steering and helmet positions.

Season update (as of Dec 15th 2017) looks like this:
GP4 2017/8 Cars Set
download this car set & menu art, totally free... >> Vics-One-Drive

Driver Menu Art + Grid Cars to go along with the carset.
You can import the .tga files into GP4, using Lo2k's GPI Browser.
  An old sample of some improvised Helmets
included free with the carset (click for Hi-Res, Hi-Def):

The Ultimate (Newbie) GP4 Guide v1.21

gp4central covers two different ways to correctly install GP4...

Option 1 - Using your original CD

  Get the Install CD for Grand Prix 4 here
  1. Install GP4 from your CD or ISO
  2. Install the Official v9.6 patch
  3. Replace GP4.exe with the Decrypted No-CD GP4.exe
  4. Run the game and configure graphics / sound, then exit
  5. Install GPxPatch by SDI Utilities
  6. Run the game again

IMPORTANT! It is recommended to install (or extract) GP4 to your Home directory, not the default Program Files directory.

IMPORTANT! The first time you play GP4, you will be prompted to configure the graphics and sound. After this is completed, you should exit the game, and then restart it.

Option 2 - Download Grand Prix 4 from GP4Central

Download Grand Prix 4 here (you may get some security warnings! ;-) )

The GP4Central version of GP4 is already patched with the Official v9.6 patch, the Decrypted No-CD exe and the latest version of GPxPatch. You just extract it, and play!

Remember to restart the game after configuring your graphics and sound (see step 4 above).

Team Editor 3.5

For editing some of the games settings, Cameras, Tyres, cars and drivers performance, Team Menu art graphics, and much much more...
WARNING: be careful when using this util in conjunction with GP4 Tweaker, because the settings from both programs can often conflict with one another in very unpredictable and very unpleasant ways!

Decrypted-GP4 :

This decrypted GP4.EXE version is required by the many GP4 utilities, such as GP4edit.

GPxPatch v4.44 :

The GPxPatch is a real-time extension system for GP4. It patches GP4 at run-time to change several aspects within the game and to add functionality of its own. This means it can change and extend GP4's display for example, or how GP4 saves hotlaps. Includes a track manager, extended save games, screenshot key, an in-game log viewer, 'gp3split' and more. My absolute favourite is the real-time telemetry Timing and Scoring on-screen display, just like the live F1 broadcasts on telly!!!

Made by Rene Smit

Wad Updater 3.4

I'll always remember when I purchased my very first computer, just so that I could get to run a (as of then brand new) simulation that I had seen advertised in a computer catalogue, called Formula One World Circuit by Geoff Crammond, the progenitor of what then became the incomparable GPx series of simulations! Long Live GP4 - 4ever!!!

'Speed' is like a contagious disease, a virus. Carried and spread by a bug widely known as the 'racing bug'. Once you get bitten, that's it! You're done for. You become infected for the rest of your life.
