Emulate other devicesIt can make your system think your controller is something else (like an Xbox controller), which helps with compatibility in games that don’t support certain devices. Create profilesYou can save different control setups for different games and switch between them instantly. Adjust sensitivity & behaviorFine-tune things like joystick sensitivity, deadzones, trigger response, etc. Keyboard & mouse → controller mappingYou can play controller-only games using keyboard/mouse by translating inputs into controller signals.
