8BitDo Pro 3 DInput Not Recognized

[ExcepJen]

Describe the bug
DS4Windows does not recognize the 8BitDo Pro 3 in DInput mode.

To Reproduce
Steps to reproduce the behavior:

1. Set an 8BitDo Pro 3 to DInput mode (by setting the switch on the back to the middle position, under the 'D')
2. Connect it to a Windows 11 PC over bluetooth and/or a wired connection
3. Open DS4Windows

Expected behavior
DS4Windows should show that there is one DInput controller connected

Screenshots and Logs

With controller connected over USB cable:

With controller connected over bluetooth:

I think the log is as expected considering DS4Windows doesn't detect a controller

Desktop:

• Controller Make and Model: 8BitDo Pro 3 Bluetooth Gamepad, Model 80GQ
• OS: Windows 11 Home 25H2
• DS4Windows Version: 3.9.9 (issue is also present on 3.3.3)

Additional context
https://ds4-windows.com/supported-controllers/ states that DS4 needs to know the controller's VID/PID to work, which it definitely doesn't know as the latest release was months before the Pro 3's launch. The controller does work in Switch mode (when it calls itself 'Pro Controller') but I'm hoping to get the analog triggers working, for which I need DInput.

I figured out how to edit the source code and add the VID/PID, and how to test it (which was the hard part). The Pro 3 is connecting to DS4Windows, but the inputs are definitely jumbled up. Most inputs add a power of 2 to a trigger's value. The gyro (the main thing I'm after) is stuck going left by default, doesn't react to yaw or roll, and reacts very strangely to pitch, going clockwise based on the upward velocity or downward based on downward velocity. I'll be looking for ways to shift these inputs around, I'd really appreciate if anyone can point me in the right direction for that.
