GP4: F1 2025 Mod v1.0 (CSM)

It's here and ready - the 2025 CSM mod has just dropped. 

As with my previous 2023/24 season mods, this mod is the base mod with everything working smoothly. So it is a kind of work in progress release, designed with future add-ons in mind. 

The mods that I have released this year have been redesigned to make use of Öggos' InjectDLL and bringing new features to current season mods. Whilst the structure has many similarities to the previous seasons, it has significant changes means this is a completely new mod. 

Much of the content in this mod has been released here: https://fongugp4.blogspot.com/p/gp4-2025-download-sources.html

All the cars have been brought to us by the RSCT team of Excalibur and Isaint. I have modified Isaint's cars a little, mostly bug fixes to stop the flickering textures and I have repositioned some of the rear wheel hubs to be more realistic. 

I have also taken all these cars and created them for internal cockpit use. This is a new feature, and with the dashes on the wheel instead of the cockpit shape, it makes for a much easier conversion. Because these cockpits use the main texture, track specific liveries work seamlessly without any additional editing.

Also new, to go with the individual cockpits, are steering wheels for each team. They are based on the 2024 versions and both internal and external versions of these wheels are in the game. As it remains a limitation to run one steering wheel for all teams, you simply need to select a driver from the CSM menu to use that team's steering wheel. 

Thanks again to Excalibur for his excellent 3D rims, however I have amended the size of them and created lods, as in previous seasons with Carl_gpgames. 

Thanks once more to Gitanes for his work on performance files, including torque files, physics and magic data files for each track. The magic data, as in previous mods, is a little experimental, it does depend on how you install your tracks and the TSM profile name you use. I have added an option to turn the torque tweak off, this occassionaly makes cars sit in their pitbox for a good while before the mechanics start work - it is not a foolproof fix though. 

Thanks to Mailson_Teles for his lovely loading screens and to jcgrj for the 2024 engine sounds.

I will talk about the new helmets in their own dedicated post, but I'm indebted to Theofilos for creating and sharing his Real Helmets Project. So far only the Arai and Bell helmet variations have been done, a very nice upgrade from before. Thanks to Excalibur for help in the conversion. Instead of waiting for the set to be complete, I have quickly painted some Schuberth and Stilo helmets on Jvinu's shape for the time being. These temporary helmets are not as accurate as the main set. 

To get this mod released, I had to rush to put some generic items in, like high resolution team arts, plain pitcrews and engineers, not in any way accurate. There remains a generic internal visor. To get this mod released, I thought it was better to have something generic, and these can be patched later as people create them. 

As always, thanks to a good number of community members who made this mod possible - some of them long gone from modding sadly, but their work is still being used to this day.
