SISR ✂️
Steam Input System Redirector
SISR (pronounced “scissor”) redirects Steam Input configurations to the system level (localhost or network).
SISR takes controllers it receives from Steam (via Steam Input)
and forwards them as emulated but more compatible controllers (indistinguishable from real hardware) to the OS.
This approach makes SISR unique for controller rebinding tools as it uses the established Steam Input system
and gives access to it’s full feature set, supports every controller Steam supports,
and provides access to thousands of community configurations (web-browsable on SteamInputDB).
It can be used to circumvent issues with games and applications that
do not support Steam Input or otherwise pose challenges, like (but not limited to):
- Games with aggressive anti-cheat systems
- Emulators
- Windows Store games/apps
- Games with broken Steam Input support
All while still providing you the full feature set of SteamInput!
SISR can also be used to “tunnel”/forward Steam Input configurations over the network to other machines, including Keyboard/Mouse.
This makes it possible to use devices like a Steam Deck as a dedicated controller without the need to stream the entire game.
The emulated controllers (and Keyboard/Mouse) are indistinguishable from real hardware and show up at system level.
SISR achieves this by utilizing VIIPER (requires USBIP).
Unlike its predecessor GlosSI, it does not use the unmaintained ViGEm driver.
[!WARNING]
Highly experimental work in progress. Everything is subject to change and may or may not work.
Expect bugs, crashes, and missing features.
[!IMPORTANT]
You do get the full functionality of SteamInput, without having to launch your games from Steam
For this Steam must still be running in the background, though.
Please read the introduction post before you get started.
