SISR ✂️
Steam Input System Redirector
SISR (pronounced "scissor") redirects Steam Input configurations to the system level (localhost or network).
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
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 WIP. Expect bugs, crashes, and missing features.
