Is there anyway to program the side volume button?

[ziadk]

Hello all, I am looking for a way to assign the side volume button to an application instead of the volume control operation, any one knows if that is doable?
If no solution for it so far, can you pleased provide me with some technical information about it so I might be able to write a program for it? thank you.

I know that it is done in both Mame and Pocket Music. But I don't know how they do it. I have not seen any general enhancement utility that lets you remap the button.
