Hi Fabio, welcome back.
I recently purchased a Moza R12 direct driver wheelbase, a Moza FSR2, and a Simsonn Pro X Ultra pedal set. It's another world coming from the Logitech G27.
I had many issues getting it to work, but most because of my stupidity. After many talks with ChatGPT and Claude, they are now working smoothly and beautifully.
I intend to make a tutorial later on how to make it work; there are different options using third-party software, but you actually don't need them.
1. All the modern steering wheels and pedals have their own software; make the configuration (deadzone, curves, strength, degrees of rotation, etc) of your devices in this software.
2. In the GP4, go to options/controls/keyboard setup.
3. Click on Change Driver Keys: set Accelerate: keystroke A, Brake: keystroke Z, Steer Left: keystroke Z, Steer Right: keystroke , , and the really important ones: Gear up: keystroke SPACE and Gear Down: keystroke Shift. Clic OK.
* OBS: make sure these are the same keys in the keys.ini (you can check in the gpxpatch main tab/ edit key binds).
4. In Controls, click on an empty user set and go to Advanced.
5. In Steering, click on Steering device, choose Controller A (X), click on it, and you should be able to test your steering in Axis X.
6. In Accelerate/Brake, click on Acceleration device, choose Controller B (X), click on it, and you should be able to test your throttle in Axis X.
7. In Accelerate/Brake, click on Brake device, choose Controller B Y, click on it, and you should be able to test your Brake in Axis Y.
8. In Gear Change, it should already be set to Change up SPACE and Change down SHIFT because you had set up the driver keys previously, and the game automatically configures the keys accordingly.
9. That's the configuration which will make your steering wheel, gears, and pedals work. If it won't work, the error is at this step. Save the configuration, then you can load it at any time.
10. Click on Calibrate and perform the calibration as requested.
11. Go to workshop/utilities and save game state.
With these steps, modern devices work well here. There are other options such as using Vjoy (virtual device), Hidhide, and Joystick Gremlin (running as administrator), which also made it work, but the other way is easier.
You can set all the buttons using software called Antimicrox, running it as administrator. It looks like it's crazy difficult to set the keys, but it is very easy if you write down the action of each button and its specific keyboard keystroke. I will send you my profile. Open the program and click on Load; my profile will be on your PC. Then you have to test which action each button does on your steering wheel and modify it in your own profile. Trust me, it is quite easy and makes all buttons work in-game.

That's it so far; hope it helps.
