Does the game have DirectInput support? I have something interesting in mind.

I think it did but the Xbox 360 controller mappings were ridiculous - START to accelerate for example - and there was no way to remap them. This new patch is supposed to add full support for the Xbox 360 controller... whenever it comes out...

Download GlovePIE: http://glovepie.org/glovepie_download.php Use GlovePIE to map your Xbox 360 controller buttons and axes to the PPJoy Virtual Joystick like this:

PPJoy1.Digital0 = XInput1.A // maps the button A to the button Digital0
PPJoy1.Analog0.XInput1.Joy1X // maps the left analog stick x-axis to the axis Analog0

Try it and tell me how it goes.
