i tried something myself by using xinput with a dll from docjoey

here is a link for in lite-c
http://boxstr.net/files/6992681_f13eg/force_feedbacktest.zip
(if it give a advert just reload the page)

it only works for xbox360 controllers so you need a joypad to xbox360 emulator
http://virusdev.ovh.org/files/
(its not a virus) you need to go to xinputmenu-> latest version (now its 3.1.4.1.zip)
read the readme for how it works

for ps3 users just download montioninjoy cable and use the 360 emulator (you need a usb cable for this so its not wireless)

not to give you bad hope but i gues the forcefeedback doesnt give the right force back for your steeringwheel

this is only not the greates way so if some one can write a dll ore header that will be asome

Thanks, the reason for that could be that X360 controller has only vibration, but steering wheels use also forces, so It can only be good done using DirectInput. It would be great if someone could help.
