[released] GP4 physics and performance calculator // updated 221006
Posted by Carl_gpgames
DOWNLOAD GP4 PHYSICS AND PERFORMANCE CALCULATOR V.0.90
I spent 100+ hours trying to find proper values for physics, torque and performance in GP4. Well, not much more to say.
The calculator is quite powerful, giving you the chance to calculate realistic phyiscs and performance with information you find in the internet.
There is still much space for improvment, so i'm happy for any suggestions.
This calculator is capable of editing and exporting more than 350 physics related values from the gp4.exe.
For non-csm users, there is Duffer's wad controller available which can directly patch the gp4.exe.
Thank you to prblanco for disassembling and exploring the gp4.exe, for the vba-code, for letting me use his performance calculator as a base for my work and for teaching me mathematics and physics.
Important note: This calculator was created with the latest excel version (O365). It might include some functions or formulas which do not work on older versions of excel. If that is the case for you, you can simply delete the formulas from the cells that show an error and replace the entries by hand.

Note: Export to .cap is still experimental, better to use patch.ini!

Congratulations on the release Carl. Surely this will only become more and more detailed as we continue to unravel GP4's inner mysteries

I understand nothing in perf for GP4 
but great work

Hats off to you Carl, seriously amazing stuff my friend! Thank you for sharing! 
Having witnessed some of this in the making, this is a truly monumental work, I just hope there is enough talent around to make the most of it.
Excellent job, Carl. Thank you so much for such a huge effort.
All you did is combine 2 existing tools that we already had.
Torque calculator was published by Patrick Closterman in 2006, sugested by me because i gave him the idea.
You can look into the credits of the work if you dont believe me

The second tool is the physics editor that you described.
Nothing new to me.

Nice work, Carl

Thank you Carl for great work and research for this calculator.
Really useful to past (and future), seasons for GP4.

Kkkk... good to know that there is continuity.

Major update!
Thanks to prblanco's help, you can now export physics (incl. torque!) as well.
In the sheet patch.ini you can now generate a code which contains all (including the values which were missing in the original phyiscs editor) known and unknown physics values. simply copy this code to the file patch.ini which is located in the settings folder of a csm mod. Just make sure to delete all existing physics and torque files in your mod before you do so (since gpxpatch patches shared memory but no the exe, it would just overwrite our code if you leave these files).
optionally you can use a hex editor to edit your gp4.exe.
Also i have added all unknown values related to the car physics in the gp4.exe.
If you find out what these values are about, please let me know.

More game changing stuff, incredible work Carl and Prblanco, so much potential here.
Superb guys! Thanks Carl and Prblanco!
