Using your DDR pad with FFR

[serioussam24]

so guys i got this awesome idea but i need some help putting into motion. i've got a usb adapter for my playstation controller but in order to use it with FFR i need to make the joystick buttons register as up, down, left, and right on the keyboard as FFR doesn't have a joystick feature (someday... ) so if any of you out there know how to remap the buttons on my controller let me know. maybe someone out there has already done it?...
