I think you have to set the type of controller used by the other player if it's a wheel controller. Have you tried looking in the options menu?Just bought a 40G PS3 and a copy of Grand Turismo. Have the standard controller that came with the console and a second Logitech controller. One controller will work with the came, but if you try to do a 2 person battle the other controller will not do anything once the race starts. We feel like we've tried everything and are having no luck getting them both to work at the same time. What are we doing wrong?? Thanks for any advice.
I haven't used a wheel controller with GT Prologue as of yet, but try looking in controller options menu (also...it might be an idea to read the manual ). Let us know how you get on!
