What is GPxPatch

GPxPatch is a real-time extension system for GP3, GP3-2000 and GP4. It patches GPx at run-time to change several aspects within the game and to add functionality of its own. This means it can change and extend GPx's display for example, or how GPx saves hotlaps.

See these screenshots for examples of GPxSAT Digital 2010 mode, which is a GPxPatch extension to show TV style overlays for race information, including standings, split times, a track map with yellow zone indicators, and much more.

Read the GPxPatch Help file for more info.

Download and Installation

Download the latest version from the download page.

To install, run inst-gpxpatch.exe and follow the instructions. If it aborts with a CRC error message, try to download it again. If that doesn't help then your system is most probably infected by a virus and you are strongly advised to run a virus checker first (with the most recent virus database of course).

It's important to install it into the main GP3, GP3-2000 or GP4 directory (where gp3.exe, gp3_2000.exe or gp4.exe is located).

After installation, GPxPatch will be launched automatically. The game can then be launched by pressing the Start GPx button. Note that GPxPatch is not an editor that changes the executable; instead, it will patch it in memory after it has been launched. So if you want to use its features you always have to start the game from within GPxPatch, or directly by using the /R commandine option.

Since version 1.22 GPxPatch links dynamically to the runtime libraries. Usually these are already installed on your system, but if they are not, you'll need to download mfclibs.zip and extract it to the installation directory. You only have to do this if gpxpatch.exe doesn't start (probably without any error messages) and you only need to do it once.

Related Utilities


HOFxLap is a hotlap/game file viewer, mainly used for authentication. The output is similar to the HOF2Lap utility for GP2, but I've rewritten it completely for GP3/GP4. Additionally, I've written a GUI version that dumps the output to a real window.

HOFxLap supports the extended data that's being attached to GPx hotlap and game files by GPxPatch. For more info, take a look at the documentation (also available in Polish, by Pawel Wagner).

The unique hardware ID logged by GPxLap is only available for automized processing on Linux servers.

If you have a Linux server and want to create a league, but don't know how to validate the games and/or hotlaps, you can download software that does this automatically. It's called GPxSite and was made in PHP by Niels Basjes. You'll also need a Linux version of HOFxLap for it. Just send me an email and I'll send it to you.


Marc Aarts has written a tool to put track related data in the GPx executable into the track file itself. This data can then be read by GPxPatch to enable tracks to be put in every slot and also to configure this data for each track specifically. CMagic is available for GP3 1.13, GP3-2000, and GP4. It can be downloaded from the download page.


F1LapView is a graphical race viewer to compare races logged with GPxLap. It combines data from each saved game to create a virtual race as if all cars raced at the same time. This is visualized by drawing a trace for each car from start to finish with a height that is relative to the time difference to the leader. There are also virtual traces of the leader for previous laps, so you can see where other cars have been lapped.


Send all GPxPatch and HOFxLap related mail to: gpxpatch@sdidit.nl (please include the GPxPatch version in the subject). Before you ask a question, please take a look at the GPG Forums to see if there's already an answer to your question. The forum is also the preferred way of asking questions because then everyone can answer your question and also read those answers.

  • Configurable keys. Edit gpxpdata\keys.ini to use different keys.
  • Marc added some bigger manana fonts for high resolutions (1024 and 1280). Edit gpxpdata\fonts.ini if you prefer smaller fonts.
  • Linking dynamically to runtime libraries, reducing the download archive size a lot. If it doesn't work anymore you'll need to download mfclibs.zip and extract it to the GP3 directory.
20 May 2001 1.21
  • Fixed sound volume, which would be very low on tracks with elevation changes.
  • Separate tyre type bitmaps for GPxSAT + option to choose them.
  • Can enter negative co-ordinates for GPxCinfo.
  • More log info for GPxSound.
18 May 2001 1.20
  • Added a new extension called GPxSound. It adds support for 3D opponent car sound.
  • GPxSAT now replaces the "Driving with" and "Viewing" messages, shows the time left in the session, has an added initial for most names, and should display most characters correctly.
  • Fixed transparency of bitmaps and font.
  • Display also works for multiplayer games now (I hope).
  • Added a fuel indicator and an options tab to GPxCInfo.
  • Solved random crash when entering cockpit.
  • ATL: also shows time difference when you're 3 sectors behind but not lapped yet.
21 Apr 2001 1.10
  • Implemented a first version of At The Line.
  • Marc added a lot more tables and options to GPxSat.
  • Custom layout gpxcinfo.
  • GPxCInfo also works in other resolutions than 1024x768.
  • Fixed random crash when entering cockpit (aka the 'GP3 Driver' bug).
  • Fixed crash when exiting cockpit.
  • Hopefully fixed flickering bitmap/font (aka the 'black font' bug).
  • Moved external pit indicator from GPxSAT to GPxCInfo.
  • Automatic font selection based on resolution (specified in fonts.ini).
  • Catch lap record from track file (and option to do this; will replace old records!).
  • Drivers with only a first or only a last name are displayed correctly now.
  • Installer won't concatenate "gpxpatch" to path anymore when changing it.
  • Logging OS type and version.
02 Apr 2001 1.04
  • Added a first beta version of 'Speed and Time' (GPxSAT), an extension made by Marc Aarts.
  • Track set file can be located outside gpxpdata directory.
  • Option to specify name of gp3.exe (e.g. gp3v.exe for GP3Video).
  • Changed memory allocation for Win2000 again.
21 Mar 2001 1.03
  • Works with GP3Video on Win2000 (no need to hold shift anymore).
  • Fixed missing info in the HOFxLap output, the average PO in the summary for example. This was caused by the fact that it doesn't recognize the car is driven by a player anymore. HOFxLap still shows the car id instead of the car nr, but that will be fixed in HOFxLap.
  • The laptime wouldn't stop running when entering the pits in a non-race session. This was caused by unfinished At The Line code, and is fixed now by finishing the part that caused the bug. So GP3 will now register a laptime in the race even when entering the pits (can't be counted as a fastest lap though).
18 Mar 2001 1.02
  • Works with gp3video again.
  • Workaround for GP3 crash when saving under Windows 2000 (debug mode required).
  • Track checker. This feature is for people making tracks. Thanks to Addie Walti for testing.
  • Option to skip intro.
  • F12 to toggle textured/wireframe/point.
  • Shift+F9 takes a screenshot without stuff added by GPxPatch.
  • Colored fonts.
  • Fixed colors during rain.
  • Realism options (which failures you can get) are logged.
  • Correct car number is logged now.
  • Fixed fastlap pos in extended data (FP).
27 Jan 2001 1.01
  • Now works on Windows 2000 Professional (also with SP1, although it seems to crash after loading a game, but this is without GPxPatch too). Thanks to Marc Aarts for extensive testing to help me solve the problems. Also thanks to Brett Canfield for reporting the problem and giving me some info about it.
  • Added an extension called GPxCInfo, which for now displays the car's gear, revs and speed in the external camera views.
  • GPxLap extended data: Added more values to the damage checksum, and some more physics values to the init checksum.
21 Jan 2001 1.00
  • First release.
