OK Matlo allow me to take it a step further and ask and even better question...
You mention GIMX currently only supports Logitech wheels. I know someone who is actually working on a program for Windows, that will take multiple Direct Input HID devices(ie a wheel, a set of pedals, a stick shifter, etc) and aggregate them into ONE device. Once they are aggregated, this program will combine them to emulate *one* Logitech G27 wheel, and Windows will think I am using a Logitech G27 instead of multiple generic DI HID devices. So, with this in mind, if my devices are being emulated to work as a G27, and Windows recognizes them as a G27, then would it work with GIMX, and in turn work on the PS4?

It will only work if it implements the Logitech protocol published here:

Thank you kind sir! I will forward this over to the dev of the app.
In the meantime keep up the great work. You are making
HISTORY by being the first person to offer real and
TRUE ffb through a console converter, and we all applaud the SUPERB job you've done!

Let me answer that interesting question: it's probably not difficult to translate the Logitech effects to DirectInput effects. The biggest problem is wheel specific commands like setting the wheel range. Every manufacturer probably has its own specific commands, and discovering how these specific commands work requires a lot of time and money. People would be frustrated to have a half working wheel. It would be great that manufacturers publish their protocol, as Logitech does.

Thanks for the input Matlo. Very interesting. Matlo out of curiosity, would it be easier to find the necessary protocols from a Virtual Device, such as the vJoy?

It's not easier to interface with a vJoy device, and it's less generic. With vJoy you can aggregate several input devices into a unique virtual FFB wheel. It does not solve the main problem, which is vendor-specific commands (like commands for setting wheel range...).

Are you planning a fund-raiser?
I for one would love to use my G25 on Forza!

There's no guarantee it can be done. It depends on the ability to use an Xbox One controller to authenticate as a G920.
I'm not planning a specific donation campaign as I'm not sure to have enough time to work on it. You can still donate in the main donation campaign, and post a comment reply to tell me your wishes.

Being the rather impatient type, I actually succumbed and purchased a G920.
I will report if it works as a client device for PS4 emulation.
If there is anything I can do to aid you in adding G920 emulation, don't hesitate to ask.
