If you own a TSW wheel by Thomas, you might find the following tweak helpful in order to get ISI’s F1 200x and the FIA GT mod to work in split axis mode. It’s quite easy to do (no soldering required), and takes all of five minutes to go through.
An update to DX9 might also help if you are still using version 8 or lower. DX9 solved all the quirks and burning hoops I had to jump through in order to get the TSW to work in non-Papy titles.
Here’s the tweak if you’re interested.
