Racing games won't vibrate without driveboard rom?

[pizzzza19]

In the WheelBoard.cpp code, there is a comment left and vibration progress not completed.

• Implementation of the CWheelBoard class: drive board (force feedback for wheel)
• emulation.
• NOTE: Simulation does not yet work. Drive board ROMs are required.

I understand that basically you need to complete real MODEL3 EPROM and it is 64KB data inside.
However, it's been 25 years since original chassis released and it can be more optimized to modern FFB steering controller and xinput gamepad.
Original driveboard parts are almost sold out everywhere and hard to find them.

epr-20985: Daytona USA 2
epr-20985: Sega Rally2

Is it possible to complete detach FFB & vibrate code from driveboard and become modern-enhanced feature without EPROM?

There was an effort to "simulate" the drive board logic at a high level, which wouldn't require ROMs. We welcome your pull request if you decide to do it :)

I added SDL_haptic to simulate wheel feedback for racing games without Z80 driveboard EPROM.
Tested with Xbox one controller.
I can PR but not sure if user already had original driveboard ROM because it should conflict each other.

*note only simulate vibration

Hello, i PR #308, please try this simulate SDL haptic build.
Disable XinputStereoVibration and you can feel both small & big haptics.

SInce i thrown away wheel controller already, FFB signals are ignored for now. (not working)
