ViGEmBus

A high-performance kernel-mode driver that emulates industry-standard Xbox 360 and DualShock 4 controllers on Windows.

ViGEmBus (Virtual Gamepad Emulation Bus) serves as the core framework for projects like DS4Windows and XOutput. It operates at the kernel level to bridge the gap between non-native hardware and the XInput or DirectInput standards. By creating fully functional virtual device nodes, it allows Windows to recognize any input source as a native peripheral. This eliminates compatibility hurdles for thousands of Steam and PC titles: ensuring low-latency response times and 100% hardware abstraction for gamers and developers alike.
