I just picked up a boxed Gravis Eliminator Aftershock gamepad from Goodwill. It was only $2.50 so I couldn't pass it up. The custom configuration program for this controller is called Xperience, the latest version being 4.5.

It's a USB controller, so Windows recognizes it without the need for any additional software. From reading the manual, it seems that the Xperience software lets you assign keypresses to buttons, adjust the sensitivity, etc.

I have other programs that can do most of that, so before I install software I don't really need, I was hoping that someone could tell me if the Xperience software would allow me to swap the functions of the left & right analog thumbsticks? I know there's probably no preset option (why would anyone ever want to use their right hand to control a game???), but I was wondering if it could be done manually by changing the axis assignments? An image in the manual leads me to believe this might be possible, but it doesn't really go into detail about what you can do.
