DS4 Tool – Control any XInput enabled game with your DualShock 4 gamepad

DS4 Tool (short for Dualshock 4 Controller Tool, DS4Tool for short, AKA: DS4 to XInput Mapper, DS4 To XInput Wrapper) is a free and open-source PS4 controller emulator, made by InhexSTER in 2013 (discontinued but still works well in some cases), based on the open-source project created by Scarlet.Crush. It works the same as its great successor DS4Windows made by Ryochan7, acts as an emulator and enables you to pair, configure and use a DualShock 4 controller on Windows OS.
