LLJoy

LLJoy is carefully designed software that allows you to emulate gamepad, keyboard and mouse input with the aid of a joystick, making it ideal in those awkward situations where various games don't present support for the aforementioned controllers. There's also the ability to easily swap button functions or reverse the axis. In this case, dead zone and saturation swapping support is available, as well as DirectInput and XInput. Profiles with settings can be saved to files.
