From the developer:
DS4Windows emulates the Xbox 360 controller so that you can play Xbox games on a desktop PC using an Xbox 360 controller. It works by remapping the user’s gamepad into a new, virtual/emulated gamepad or by directly mapping the real gamepad to the user’s keyboard and mouse. This tool can also be used to interface Nintendo and PlayStation controllers.
