Hi all, I tested this with a DFP, G27 and WiiWheell was looking good, but then I found a small bug. It seems that the requested mode is case sensitive. 'G25' works, but 'g25' is seen as a request for a 'DF-GT' and causes and error. Sorry I didn't see this earlier. I'd be happy to apply and fix later, but I suspect Jiri will say fix it first. Simon PS. Resent via Gmail as my hosting is having issues.
