I have SC1 and would like to connect with old RBR, but after connect, game didn’t see nothing 
One of my friend said to me if propably need any special outside app to turn on it, for reason really old physic.
Best Regards

Do you not get force feedback? If not might need to set the wheel to 900 degrees so the game sees it and then switch it back to 540. Worked for me if that was the problem.
RBR works just fine, however calibrating with e.g. 270 degrees steering ratio and pressing e-stop might be required in assigning axises so that the game sees the axis moving fast enough and near/over the axis limit.
