This is a bug fix release to make GPxPatch compatible again with GP3 and GP4 1.00.

This version should work in combination with CSM mods and TSM. See the changelog for a list of changes.

In co-operation with Addie Walti, full GP4 custom track support has been implemented. Custom track builders should read the GPxTrack documentation if they want to comply fully with GPxPatch, although effort is done to support existing custom tracks without modification.

Other improvements include 100 panels and color/alpha blending in GPxCInfo, tyre type in lap log, and more.

Addie released a revised version of the Circuit de Pau / France. It's the first track to support GPxPatch 4.00. I've used this track with much pleasure to test the new track manager.

I've published the GP2Lap source on GitHub. A small part related to saved game authentication is left out.

This version enables you to customize the keys (X and C) for looking left and right in the cockpit.

Had a discussion with MerlinC2000, which resulted in adding an Inverse Corner Radius item, and a few extra options.

An Android app to show rally results organized by mijnrally.nl. Only interesting for the contestants involved.

This version contains some fixes and minor features. Happy 2009.

Simple commandline utility to show information about a replay and optionally extract the car setup to a file. Handy to keep in your Replays folder.

This version contains some fixes I made right after I released 3.91 but never made it into a new version after I stopped all GPxPatch related activity completely until recently.

Using 3D instead of 2D data files for LFS track map (track itself is still drawn in 2D).

Since I have trouble with my old forum I have temporarily changed the forum link to point to the forum at RealGPx. Thanks to Lo2k and Duffer for providing this forum.

News items can be read through a RSS feed now.

Works with GP4 1.00 again and contains some GPxSAT fixes and changes.

Includes new GPxSAT features by Ricky. Also includes several other things and fixes.

Added a pit siren and several other things.

Fixed some problems found in 3.81, updated the German translation (by Uwe Mönks), and updated the blue theme notes.htm (by lo2k).

See the changelog for a list of changes.

Works with GP4 1.00 again.

Added GPxSound for GP4.

Contains random seed for unlimited practice session.

Fixed a crash when adding files using the normal file dialog.

Contains the new GPxSAT digital 2004 mode, by Markus Krötz (graphics by Pablo Borzi).

See the changelog for a list of changes.

Also works with GP3-2000 setup files now.

Also works with GP3 and GP4 setup files now.

Updated physics patching so it understands GP4Phys 1.03 .g3p files.

Yesterday the foreign language dll's were not working for the GPxSAT and GPxCInfo tab. It should work again in this new version (uploaded it on 10-02-2004 at 1:10 AM).

Added an extended pause mode. This means that when the game is paused you are able to do what you always wanted to do but were not able to. The option is turned off by default, in case it gives certain side effects (I didn't get any, but I didn't test it extensively). You can find the option on the main GPxPatch tab. Setting the option to indeterminate requires you to press Enter to active it when the game is paused.

Pitstop bug fix is now optional.

Shows information about pitstop bug fix and minimum/maximum speed each lap (since GPxPatch 3.56).

I've tried to fix the pitstop bug in GP4. Please report and send a saved game of it if it still happens.

Announcement: GPxSAT is under development again. Markus Krötz decided to try to take over the project to add some new screens. The first screen he has added is a penalty screen. He also fixed a few bugs.

Adds driver input items and rotating image control in GPxCInfo.

Adds driver help items in GPxCInfo (download this file for an example; unzip in the gpxpdata\pnl directory and select helpdemo\panel.ini in GPxCInfo).

Adds a GUI for creating custom panels.

It was translated by Peter "jatori" Groh and Tom Dobrokovsky and it is up to date with version 3.50.

• Showing if save/restore car state feature was enabled.
• Added support for quicklaps files.
• Fixed gpxlap_stat_f5 to be gpxlap_stat_f7 in alternative output.

Adds a pit setup menu and save/restore of car state.

Enables in-car setup changes (brake balance and differential).

Added support for multiple tracks when reading LFS RAF files.

Fixed setup shown twice and fastlap position for GP3-2000.

Just one fix: session specific fuel laps and consecutive cars would be 0 instead of the default when empty (thanks David Winder for finding this).

This version still doesn't contain in-car setup changes yet, but it does contain some fixes and new little features.

Added support for GPxPatch 3.36.

This version doesn't contain in-car setup changes yet. It's just meant to get the old stuff released first.

It is now compatible with GP4 1.02.

Now considers reserved slots when joining a server.

Version is the same as yesterday, except it contains a Russian translation of the dialogs, done by Yuri Kuznetsov.

Contains a fix for the track problems.

Contains bug fixes and a few new advanced options.

See changelog for the list of changes.

This time it includes the Spanish translation.

See changelog for the list of changes.

Some bug fixes.

Added support for GP4 1.02, added tyre and plank wear, and fixed some bugs.

GPxSound (GP3 only) seemed to be broken in version 3.30, so I've uploaded a new 3.30 with a fix for it.

Added support for GP4 1.02 (patch 9.6). See changelog for the complete list of changes.

The graphics in the installation executable were not updated by accident. A new inst-gpxpatch320.exe has been uploaded to correct this problem. If you had already downloaded it before 11 am CET then you can download the graphics separately here.

See changelog for the list of changes. Please note that it does not support GP4 1.02 yet (patch 9.6).

See changelog for the list of changes.

Added support for Live For Speed. See changelog for the complete list of changes. If you haven't checked out this sim yet, go give it a try. It has a free fully functional demo, including support for multiplayer over internet.

Maarten (the board maintainer) has implemented new search code in the board, since the old one didn't scale properly with the increased number of messages on the board. The new one is very fast, but still has less features:

• you can only search for single words.
• you can only search in message bodies (not author, subject, ip, email).
• the score of each result is always 1.
• all old messages are currently being added to the search index, but at the moment only the last 3 months or so have been added. The board may be locked while old messages are added.

Luc Segers from GP4 League pointed out to me that the car behavior was different between using GP4Phys.exe and GPxSet to patch the physics. The checksums were also different. The reason was a bug in the patching of downforce coefficient and will be fixed in the next version. In the meantime, I suggest that leagues using custom physics mandate that those are patched using GP4Phys.exe. Sorry for the inconvenience.

This version enables all graphical features for GP4, including Marc Aarts' GPxSAT, which has been extended to include the digital tv timing mode. Note that to disable GP4's timing info you have to turn off the option "tv overlays" in the graphics options menu. Also note that GPxSound does not work for GP4 yet.

After having been down for more than a month the forum is finally up again.

Quick fix that solves the problem of sessions not stopping.

Shows frame rate changes that was added in GPxPatch 3.03.

There is a bug in GPxPatch 3.03 that sets the post-session duration to 6000 seconds instead of 6. You can work around this by putting the following line in gpxpdata\gpxlap.ini, under a section called [Misc]:

RaceOverDuration=6

Logs frame rate changes and fixes some issues. Also added German (by Uwe Mönks) and Italian (by Antonio Russo) translation.

See changelog for the list of changes.

Added support for GP4.

Added support for GP4 and added some new features. See changelog for the complete list of changes.

Fixed bug that caused 3.01 to crash on any GPx version except GP4.

Made some bug fixes.

Fixed some GP4 setup issues.

Added support for GP4, and shows split times for each lap.

See changelog for the list of changes.

I finished this version already half a year ago, but never released it. See changelog for the list of changes.

With this version you can see what random seed was used.

This one should really have a working GPxSet now, hopefully. I have also fixed the edit button in GPxTrack.

See changelog for the list changes.

Added support for .g3p physics files and implemented a random seed feature.

Important note: if you load a .g3p physics file, make sure it was saved with GP3APE 1.03 and is 196 bytes. Anything else will give undefined results.

Added the cc checksum to the -a output.

No new features, just added compatibility with GP3-2000.

Removed trailing 'h' from the cc checksum (it was to indicate that it's hexadecimal, but that's not relevant). Also updated the changelog in the HOFxLap documentation, since it was missing some entries.

To see the small list of changes, see the GPxPatch changelog and HOFxLap documentation. It boils down to authentication support for GP3-2000.

Today is the birthday of GPxPatch, which I want to celebrate with the announcement that I will release new versions of both GPxPatch and HOFxLap (currently being beta-tested), containing support for authentication of GP3-2000 saved games/hotlaps, and thus enabling leagues to use GPxPatch together with GP3-2000.

For a list of changes, see the changelog.

This is the last version of GPxPatch for the time being (unless it contains serious bugs), so please don't ask for more features to be added.

This version extends the Art tab with more options. Livery sets are now replaced by season sets and car sets, so any livery sets for 2.01 will not work with 2.02.

For a complete list of changes, see the changelog.

Mainly some bug fixes that were introduced with version 2.00. It also adds the possibility to select a car shape to use so you don't have to use Paul Hoad's Car Editor to patch the exe.

For a complete list of changes, see the changelog.

Marc Aarts has released his CMagic 2000 program through my site (he has closed down his own site unfortunately). This program is needed to put magic data into tracks that can be read by GPxTrack. This allows you to put each track into a different slot. It also allows track makers to finetune their tracks for GP3-2000. It can be downloaded from the download page.

Note about the GPxPatch that was released last night: There was a problem with the liveries paths, which resulting in either a GP3 crash or in completely transparent cars. I've fixed this now and uploaded a new installation file. If you have downloaded it before Sep 21, 10AM CET then you need to redownload it. The correct inst-gpxpatch200.zip should be 381837 bytes in size.

This version works with GP3 1.00, GP3 1.13, and GP3 2.00 (GP3-2000). It also adds a livery manager so you can have 22 different liveries (thanks Marc for helping out with this, hopefully you'll return and release CMagic 2000).

For a list of things added in this version, see the changelog.

Now possible to retrieve a server list from WON that contains only servers running a specific mod (see changelog).

A bit unexpected since it has been 18 months since the last update, but there's a new version of GP2Lap. It includes a fix for the country adjectives (Frank fixed this a long time ago already, but it was never released), and it adds a new page ('1') with info about gear, revs, and speed.

Seems 1.05 couldn't load hotlaps anymore. This is fixed now.

Added an option to change the font, since some people complained about the font being too small.

Fixed a few bugs (see changelog).

I got a good tip from Cesar Mello from Brasil regarding multiplayer games. If it would be possible to make GP3 use an IP address instead of doing a LAN broadcast message, it would be possible for the client to join a session over the internet. So I went to work and patched GP3's calls to DirectPlay (just a small hack). Now we could do a multiplayer session over the internet. Just one warning: you'll need a good connection for this, and even then you can't really play with more than 2 players! Some people already played over the internet by using Kahn, and this is just the same except you don't need Kahn anymore.

This version also has the lap times and fastest lap times (without splits though) listed in ATL in non-race sessions.

The number of players and the maximum number of players are now split into separate columns.

Now you always use the host name instead of the ip address. Host name can be resolved from the ip address in the server properties dialog.

Thanks to Claudio Alonso, who offered to translate the GPxPatch documentation to Spanish.

I'm happy to announce a new member on the GPxPatch team, Radu (GPXFan). Radu is going to help me with the event sounds. Specifically, he's going to work on multiple sounds for an event, and on a sound queue so they will be played after each other, not at the same time. Actually, he has done most of the work already and sent me his source code. I was impressed so I asked him to join the team. Good luck, Radu.

Now you can manually add a server by host name (requested by Colin Buckler).

Adds a first version of event sounds. See the changelog for more information.

Minor update that fixes some problems and adds some small stuff. See the changelog for more information.

Minor update for showing the reserve_slots rule of servers using the Admin mod.

You can use the regular forum again.

The forum is down again. For now you can use a temporary forum to post your messages.

See the changelog for more information.

This version adds 3D opponent car sound to GP3. See the changelog for more information. Note that you can use the 'T' key to see the time left in GPxSAT.

Now possible to load GPxLap extended GP3 saved races.

The latest version of GPxPatch has fixed some problems but also added some new ones. I'll summarize the problems that have been reported. We're trying to solve them, so you don't have to report them to us anymore.

• Black font background and blue background in finish flag. This is probably caused by the fact that some video cards don't support 3D colorkeying (this means making a specific texture color transparent), most notably TNT, TNT2 and similar video cards.
• White blocks instead of text. Still investigating this one.
• Nothing visible in linked multiplayer mode. This bug is not new, but fixing it has received higher priority since the latest additions of visual features.
• Different grip and/or other physics. This is a tricky one, as I didn't change anything physics related on purpose.
• gpxsat.log says that the hooks fail.
This is bug in the error handling. The hooks work fine, so don't worry. If GPxSAT doesn't work then the problem is something else.
• GP3 crashing after a random period when using GPxPatch.
• Some characters not shown. Most notably in German. Marc changed the font for this to fix it, which you can download now.
• GPxTrack doesn't write back new records to custom track file. This is by design, since I don't want to update track files. I'll try to make a patch that can save records of any track and custom track into a separate .ini file, which also solves the problem of records.rec only containing records of 16 tracks.

One thing that didn't make it into GPxPatch 1.10 is customization of the positions of the external car info (GPxCInfo). You can do this manually by putting a gpxcinfo.ini file into the gpxpdata directory and put the following in it (this example will put it to the right; negative numbers are added to the right/bottom):

[Misc]
GearX=-6
GearY=300
RevsX=-6
RevsY=350
SpeedX=-6
SpeedY=400
PitX=-6
PitY=450

Contains a first beta version of At The Line. Also contains bug fixes and a much improved GPxSAT. See the changelog for more information about what's new.

Fixed the car number in the GPxLap output (thanks to Willem van der Steen for reporting this bug).

Temporary forum messages have been merged (thanks Maarten)

Maarten van Schouwen, who maintains my forum, has provided for me a temporary alternative. It can be found at this link.

The server running the forum is currently down. Maybe this will last the whole weekend.

As promised, a new version of HOFxLap. To see what's new, check the documentation.

Contains a first beta version of Marc Aarts' Speed and Time extension. Some other new things can be found in the changelog.

This release fixes the reported bugs (see changelog).

I got some bug reports for GPxPatch 1.02, which I'll summarize here:

• It still won't work with GP3Video on Win2000. To work around this, hold the shift key wile pressing the Start GP3 button. It will most probably work correctly then.
• Some info is missing in the HOFxLap output, the average PO in the summary for example. This is caused by the fact that it doesn't recognize the car is driven by a player anymore. I'll fix this soon.
• The laptime won't stop running when entering the pits in a non-race session. I shall fix this soon too (it's caused by unfinished At The Line code).

This release does NOT yet contain tv style info or at the line. It's just to release some bug fixes and some small features I have finished last month, but were never released. To see what's new, take a look at the changelog.

This week I've been busy redesigning the site, so it all looks more consistent and it's easier to navigate. It's optimized for speed and for Opera.

Main things added in v1.01: Support for Windows 2000 and view of gear/revs/speed in external view (thanks to Marc Aarts for both testing on Windows 2000 and for supplying the font).

Added in v1.02 is support for GPxLap extended data in saved games/hotlaps.

This is the successor of GP2Lap. It's a real-time extension for GP3. The first release includes a track manager, extended save games, screenshot key, an in-game log viewer (hardware acc. graphics mode only), 'gp3split', and more.

Note that the current HOFxLap can't view the extended info in saved games/hotlaps yet. I'll release a new version that supports it probably tomorrow.

A serious problem was found, it'll take me a lot of time to fix this, sorry (and this was the last time I set a release date).

Looks like I didn't make it this weekend either. But it's only a matter of the finishing touches before I can release it. Don't set your expectations too high though, because there's still a lot of features missing (compared to GP2Lap).

Sorry for the wait, but it looks like I didn't finish it in time before the new year started. I've got it ready to release, but I'm just adding a GUI launcher to it and a help file, so it'll be easier for everyone to use. I hope I can release it this weekend. I'll need to sort out these pages too, actually...

• Besides a lot of new info and some bug fixes, this version includes a GUI version. Read the help file for more info about bug fixes and added features.
• Of interest to file checkers is the fact that for hotlaps I've changed the moment in time of some of the fields. They are now shown as they were at the start of the hotlap. The reason is that the other time frame is at the moment of saving the hotlap, which is arbitrary. Affected fields are: driver aids, weight, and fuel laps.

• Andy Barganski is working on official timing info.
• Frank didn't have time to work on GPxPatch unfortunately.
• What I have so far works well with GP3 1.13.
• I'm currently working on HOF3Lap. Marc Aarts is doing some testing for us, and is also working on his own hotlap checker (a GUI version). I've planned to release HOF3Lap this weekend, which will be similar to the HOF2Lap of the pre-GP2Lap era. It will also work on Linux and some BSD variants.

I've replaced the old forum with a new forum. The reason is that the old forum was using an ugly advertisement banner and also javascript. The new forum was made completely in php3, and doesn't use a banner (because it was made for free by Laurent at PHP lab). I've done some effort to copy the messages of the last seven months to the new forum, but I lost the thread hierarchy and the dates for them. Thanks goes to Sweep for help and providing a server to run the forum on.

I've made a votelet (poll) to find out what graphics mode most of you are using in GP3. This will give me some feedback that will help me make some priorities in making GP3Lap. Thanks in advance for your answers!
