Currently, Joysticker Pro does not work with Joysticker scripts, but they could be made to if needed at some point in the future. The funny thing is, in order to do that, I'd end up using a portion of Joysticker to accomplish it because it utilizes the Windows API for its joystick I/O. The WinAPI has been around for a very long time and won't go away anytime soon.
P.S. I just looked at the controller you are using, and it is very cool. I didn't know anything like that existed.
