ViGEmBus, HidHide, HidGuardian, ScpToolkit and DS4Windows: the driver stack around InputMapper.
ViGEmBus is the virtual gamepad bus driver that lets Windows applications create virtual Xbox 360 and DualShock 4 controllers. If you use InputMapper 1.7 or DS4Windows, this driver is the piece that actually places a virtual controller into Windows. Without it, your mapping software has nowhere to send its output, and games will not see…
Search for help with an older InputMapper install and you will quickly land on a 2016-era guide telling you to install ScpToolkit. At the time, that advice was reasonable. Today, following it blindly can leave you with an outdated driver stack, a known-vulnerable component, and conflicts with the modern tools you actually want to run….
Double input is the most common InputMapper problem: you press a button once and the game registers it twice, menus jump two entries at a time, and characters perform an action plus the action mapped on top of it. The cause is almost always the same — Windows sees both your physical DualShock 4 and…
If you have followed InputMapper for any length of time, you have met two similarly named tools: HidGuardian and HidHide. Both exist to solve the same problem — hiding a physical controller so games only see the virtual one — but they come from different eras of PC controller mapping, and they work in fundamentally…
