well i have an old ps2/xbox steering wheel lying around and have decided to gut it and cut a hole big enough to stick a SIXAXIS controler init. currently i am just waiting to get my dremel charged up to finish the cutting and post pics of it and maybe even a small vid of it in action. i also will post a tut on it.
games i know it wil work on :
motorstorm
nascar 08
and waiting on GT5P to arrive ill see if it works there too.
