GP4: ICYMI March 2025

For the first time in 2025, I wanted to update you on some of the new downloads and updates available for Geoff Crammond's classic game. 

It amazes me that over 20 years after the release of the game that there are new tools and editors to improve the game are being made available. 

I'm also in awe of those who have the time and commitment and devotion to make a whole track. 

Also in this update is a slight update to an existing mod and some new sounds to enjoy in GP4. 

Before we get going with the recent updates, you can check out, separately, all the 2025 downloads available here: 2025 Downloads

Individual Meshes & Textures - updated and improved
There's actually been multiple updates since this was first released. By injecting a dll into the game, it allows previously impossible options that are now available to editors. Plus, with the old csmprocess file, it is possible to enable these things via CSM.  Individual internal cockpits, a proper internal cockpit visor, individual collision meshes and a fix for the 3D rims reversed tread bug are all now possible with this tool.

GP4 Mesh Tools for Blender - updated
This little update fixes a bug that introduced some weird graphical glitches when updating pit props. Thanks to Öggo for working with me to diagnose and fix the issue.

GPF (Menu Fonts) Editor
This lovely new tool not only helps you edit the font files in the menus for GP4, but it also opens up the possibility to have high resolution fonts too.
by Öggo  | Info

Helmet Visor Colours
Another helpful fix is an age annoying uneditable item in GP4. Originally, the Arrows drivers had orange tinted visors and one of the Minardi drivers had a green tint. This was great for 2001, but it was annoying it continues to be seen in mods. Now this can not only be remedied, but all visors are now customisable per driver.

1998 Trackpack
Following on from created lovely high resolution trackpacks for 1996 and 1997, we now have the same treatment for the 1998 tracks. Lovely work in giving some of these older tracks a new lease of life.

1987 non-CSM mod updated
Thanks to Jose Gomes on doing some edits to the existing non-CSM version of the 1987 mod:  - change to FULL HD views and positions - change cockpit and steering wheel - fix mirrors - fix crash model of gp4 cars - update sound and commentaries  At the moment there is no CSM version of this mod, but hopefully that will be done soon.

1999 Williams FW21
It's fantastic to get new cars being added to the GP4 community. This beautiful Williams comes with 4 shape variations and a full season's worth of textures. The 1999 grid is starting to fill up with some fantastic quality cars.
by Hega (Quickslick, kedy89)  | Info

2023 Lusail International Circuit, Qatar
Built on the dat file by prblanco, drt01 has carefully done the 3D work and created a fantastic atmosphere to this track that has now become a regular on the F1 calendar.
by drt01 |  info

Le Mans Petite Sarthe - 2024 version
Due to the limitations in GP4, we have to settle for a shortened version of the famous track used for the Le Mans 24 hour race. Thanks to Davide for updating the track to 2024 standards, ideal for the IMSA vs WEC mod I worked on last year.
by drt01 | info

Adelaide International Raceway
This is a real race track from Viking75, and it was largely used for touring cars and junior single seater races.
by Viking75 |  info

San Carlos, Venezuela (Fictional track)
This fast track has the horizon from San Carlos in Venezuela.
by Viking75 |  info

Pasadena Raceway (Fictional track)
Viking says "I am exploring the limits of GP4 builder's possibilities. I built a 19 km circuit, with 3924 sectors. It cannot go beyond 4000 sectors. I added a lot of heavy objects to see if it still worked and it does. The lap time is 4mn 25, very long. The circuit is very winding but with very wide turns. Thank you to F1 virtual for the building at the pit entrance."

1979 Ferrari 312T4 Engine Sound
Jose Gomes continues his good collection of engine sound updates with this one from the end of the 1970s. This Ferrari sound fits really well specifically with the 1979 mod, and other similar era seasons.
by jcgrj |  info

F1 WGP Pit radio sounds
This is a fun add-on with sounds from the classic F1 WGP game. These sounds can be implemented via GPxPatch
by RegularJohn | info

And some news from me...

1994 Tyrrell 022 Yamaha
This is not a new download, but I was asked if I could share the 1994 Tyrrell separately from the mod. Here it is as a stand alone download, the Australian GP version.
by fongu | Info

and there's a new page on this blog: Fictional Cars

Well, all that's left to say is happy racing. 

GP4: ICYMI - January in GP4

There is a huge amount of work that goes into mods for GP4, and sometimes there is a large gap between downloads. But this past month has seen some significant downloads become available and, in case you missed it, here's some more info about it. 

Zaz Tools Update 1.27c by Zaz
	Update 14/01/2024: ZaZ fixed an issue with the PreExecute-variable. The fix is now included in version 1.27c.  I know Carl has had some issues with the mediafire account, but here's a working mirror link.
	Info

IMSA 2.0 Random
	We have Meteoro405 to thank for the CSM update, and this updated mod makes full use of its new features.  Essentially, there was a bug in the loading up bat files. Ariel has written a bat file that produces random variables each time you load the mod.  There are also various track livery options that there are many possible car wad files possible with just a few clicks.
	Info

WEC HUD by AugustoGibim
	TV Style onboard cam for WEC Series 2023.  This HUD goes great with the mod above.
	Info

F1 2000 Mod by rracunis
	Hega has been releasing a lot of 2000 content in the past year, making use of EnzoJZ's models that were left gathering dust for over a decade. They've been updated, mapped and painted, along with helmets, cockpits and other things. Rracunis has kindly put it together in a mod, based on my 1994 CSM mod structure.
	Info

Bell Helmets Pack (XFM-1, M3, AFX-1, Vortex) by Öggo
	Öggo has been slowly working away at various late 1980s - early 1990s helmets, and we've had fantastic Arai, Rheos and Shoei helmets already. Now we have four new helmets, all of them various Bell helmets used in F1 and Indycar. You'll also see these helmets in Assetto Corsa in not too long. I've already started to use the templates on some of these helmets already, I look forward to sharing some of them with you in the not too distant future.
	Info

Sebring International Raceway by drt01
	This is another brilliant track addition to GP4. drt01 has done a fantastic job putting this together. The track is really bumpy, probably the bumpiest track I've tried.
	Info

This is not a new release, but new to my downloads page. 

F3000 International Masters by yaya
	This is a little conversion from Race07, nicely done by yaya.
	Info

Thanks for your support and keeping this site going. Keep racing. 

GP4 in 2023 ICYMI

As 2023 draws to a close and we look forward to what might be in 2024, I thought I'd end the year with a bit of a retrospective. My blog tends to focus on GP4 content that I'm releasing, as well as compiling links to the current season. Occasionally I'll add things to my downloads section (although not quite everything).

We've had a couple of epic years of advances and great content created for GP4, and I thought I'd do a summary of 2023 GP4 downloads not created by me, just in case you missed it. 

2000 cars, helmets & cockpits by Hega, Tweaker Visors & pitcrews & engineers by kedy89
	The big news for 2023 is the gradual release of cars from the year 2000. The 3D car shapes were created around 15 years ago by EnzoJZ. Besides the Ferrari and the McLaren, the cars were all under 10,000 polygons and used a unique method for controlling normals (which is stunning and stands up today).  Enzo had passed on his blessings for these to be finished, and initially, Coldblood took the lead in updating and releasing these cars, but sadly progress ground to a halt.  After some persuasion from some members of the community, Hega took on the job and practically re-worked and finished every car on the grid and created a great helmet set to boot.  Nice to see Kedy89 back and releasing updates, and we have engineers & pitcrews using 32bobo32's excellent HD template.
	Info

CAP Converter by Öggo
	We also have a couple of different releases from Öggo.  This is a simple little tool that helps with CSM mods and is also compatible with Wad Controller by Duffer.  Essentially, these are mods to the GP4.exe. Various people over the years have released them as CAP files to put into the 'Patch' folder of your mod and CSM would do the rest. Alternatively, CSM allowed text patch files in Hex, allowing you to see what the code did. Now you can convert between the two (it is best to stick with one method or the other rather than using a mix of both).
	Info

1991 Rheos helmet & template by Öggo (based on EKO Sim Racing & ASR Formula's version)
	In case you've missed it, Öggo has been slowly been creating incredibly detailed shapes from the 1990s.  This is a Honda/Mugen helmet used in 1990/1991 by Senna and Berger. This helmet comes with textures for both drivers as well as a template for you to create your own skins.

1993-1997 3D Rims set by Öggo, Alesi_fan, Turbo Lover
	This is a fantastic set of tyres and rims done to great detail and yet perfectly playable in GP4.  The rims from this set have already been incorporated into the 1994 and 1995 mods via some updates released on this site.
	Info

2001 3D Grooved Tyres by Zifox (updated from rims by Hega, EnzoJZ, Coldblood, Vesuvius)
	On the topic of 3D tyres and rims, Zifox has created 3D grooves for the Michelin and Bridgestone tyres for the early 2000s mods.  The problem comes when the game applies intermediate or wet tyre textures, it does not change the shape, but Zifox has done a great job to seamlessly make these textures fit the shape.
	Info

1997 add-on package by SkaningeN
	Moving onto the SkaningeN section, and we have a whole host of updates from my friend Eric. He's done many long and painstaking work or creating in-season changes to shapes, liveries as well as special helmets. Here's the 1997 add-on pack, which includes the original cars converted from F1C, as well as the hi-res converted from Asseto Corsa and Soulbringer's excellent McLaren. Full credits to the original authors are given in the link below.
	Info

2001 add-on package (for Hega's cars) by SkaningeN
	SkaningeN has put together this nice pack of additional shape updates, mostly rear wing changes, for Hega's cars from 2001.
	Info

2002 Packages for Sauber & Jaguar by SkaningeN
	We're all saddened that the 2002 mod from Soulbringer and Kedy89 was pulled. They were well on track to completing one of the most detailed and top quality mods in GP4.  There were two cars missing from their catalogue before they removed their content, so SkaningeN has updated the old F1C conversions for the Sauber and Jaguar. I was glad to help on the Sauber with the alternative nose-cone and front wing.

2003 Helmet set & shapes by SkaningeN
	Skaningen has updated the 2003 helmets and included shapes by Daimon and Jvinu (updated by Hega) and put together this great set of high resolution helmets.
	Info

	These are updated on EnzoJZ's and Lee's tyres. These are 2D rim versions.  For more 2003 updates previously released, you can see a collection of them here
	Info

2004 Helmet set & shapes by SkaningeN
	Much like the 2003 pack, this 2004 pack includes helmets from Daimon and Jvinu (amended by Hega). I had previously remapped Daimon's helmets to fit the textures of Jvinu. This set also includes the Bell helmet by Eugenio Faria, which was also remapped by me. This Bell helmet was used from mid-season 2004 to mid-season 2005. You'll also find my all new Massa helmet included here.
	Info

2004 2D Tyres & Rims by SkaningeN
	These are updated on EnzoJZ's and Lee's tyres. These are 2D rim versions.

	These are updated on EnzoJZ's and Lee's tyres. These are 2D rim versions.
	Info

	Erik continues his work into 2006, with helmets originally by R0b3rt0_38, Raulongo, Overgone, MDBSnake, Öggo, b-tone and Alex Schumi. Some remapping of Daimon's helmets were done by me.
	Info

	Once more, EnzoJZ's and Lee's tyres are adapted to 2006 versions. These are 2D rim versions only.
