Need some advice please

Im just after some advice on what can and cant be done in regards to making an adaptor or program to remap a g25 to work with the 360?

For it to work someone needs to be able to write software to convert HID (PS3, PC <G25>) to XID (Xbox 360), which has already been done in reverse for xbox 360 controllers to work on PC so i dont see why it cannot be done for pc >> xbox.

Also an xbox console can pickup a HID Usb device so it has to be do-able.

If we can work something out there will be money involved for them because I know for certain i could sell many of them very easily. I have seen probably 500 posts in the last month of research with people wanting this. Its a gold mine if it can be done once and replicated easily.

Weather it can be done in a software based form and writen in xbox code, or some sort of inbetween adaptor can be made to remap the buttons to axis.
Something like this >> xcm.cc/xcm_xfps_360.htm << although that does not work with a g25, it can be used to remap a ps2 controller to work on xbox and a ps2 controller wouldnt be XID.

I realise stuff like force feedback etc is going to be near impossible, but even if a device could be created to remap the controls to the ingame/controller controls. For example convert the joystick(steering buttons) to the steering axis's on the wheel, then the brake button to the brake pedal axis.. etc etc, as for the H-pattern again i'd imagine it would be too hard but even if people could have the up and down shifter it would make them happy which again would be remapping the two shift up and down buttons to the up and down axis for the shifter.

Just after some advice from someone that understands all this fully to see if it can be done.
