Is there a way to use combined axis linking the accel and clutch pedals instead of accel and brake on the G25? This would be awesome for flight sims... (rudder emulation). Those pedals are on the outer side, and have similar pressure resistance... perhaps an option to be introduced into the next driver version? 5.03??

The programmer responsible for a great little racing game called Trackmania has done just this. Annoyingly the game is all about toy cars not aircraft sim! The accelerator acts as accelerator/brake/reverse - cool in an aircraft but difficult if you are careening around bends on an insane track! Perhaps he will let Logitech have his routine to incorporate into their profiler?

Well, I've discovered that you can do this using two little apps called "Parallel Port Joystick" (known as PPJoy - google it) and GlovePIE.

The first creates a virtual joystick in your computer, and the second allows you to create a script to maps-and-mixes the real axis and buttons of other joys to the virtual one. Then, inside the game, all you have to do is point the controls to the virtual joystick and that's it.

Below is the script that I've used to map the two most external pedals to emulate a rudder, and the central to be the wheel brakes:

//Combined throttle (Y) and clutch (dial) make virtual joystick axis.
PPJoy1.Analog0 =  0.5*Joystick1.dial - 0.5*Joystick1.y
PPJoy1.Analog1 = Joystick1.rz

So now I'm using my old F22-TQS and my G25 pedals as a combined set, and it works just perfect.

Note that the axis used in this script are functional for my installation. Every time you reinstall the G25 or PPJoy (if you reformat your system, for example), you may have to remap (change) the axis. First time I was using Joystick.x instead Joystick.y. This isn't a major problem, unless you reinstall your system a lot (and then is just a matter of reprogram the script).

I've tested this under Win XP and Win7 32-Bit.
