ATTENTION: GloSC is currently being rewritten, and renamed to GlosSI ([Glo]bal ([s]ystemwide) [S]team [I]nput)

No ETA when it's done
No support until then.

Looking for contributors!
As the past has shown, I have way to less time on hand too maintain such a project.
Reach out via Discord/E-Mail (But get to the point right away, please, I get way too much spam)


Snapshot builds can always be found -> here <-


GlosSI or [Glo]bal ([s]ystemwide) [S]team [I]nput, formerly knows as GloSC (Global Steam Controller), is a tool that allows one to use Steam-Input controller rebinding at a system-level alongside a system wide (borderless window) Steam overlay
All complete with per application bindings and working rumble emulation.
GlosSI can, but isn't required to, launch any of your favorite games or applications and directly add them to Steam, be it Win32 or Windows Store (UWP)!
It is the tool to enjoy any game that has trouble with Steam and/or add extra functionality to your Steam-Input needs

Windows Store, Reshade / SweetFX, Origin, Uplay, Emulators and more with no hassle

How does it work? / What does it do?

GlosSI creates and adds a (or multiple) non-Steam shortcuts to Steam. When one of those is launched, a transparent, borderless window appears in which you can use the Steam-overlay. You also get access to touch- and radial-menus and other functionality normally only present in Games

In addition to that, Gamecontroller-inputs are redirected to the whole operating system, so that they will work with any game or application
Real Gamecontrollers are hidden from other applications, so that they can't interfere with your game.

This brings full Steam-Input functionality to the desktop and any other application Steam-Input might not have worked before

Games do not need to be launched using GlosSI.
If the "Start Application" option does not work, launch any GlosSI-Shortcut from Steam, followed by a game or application.

What this is not

  • a replacement for Steams controller configuration tool.
  • a Steam remote play / steam game streaming solution. (That being said, it can work, but is not guaranteed to.)
  • Old versions (GloSC, Global [S]team[C]ontroller) where never designed to be used with anything other than said controller, GlosSI can be used with any controller.

Join the GlosSI discord here:

GlosSI consists of

  • The "GlosSITarget" which does most of the magic - Showing the overlay to the user as well as talking to the ViGEm-driver for system wide Controller emulation
  • A config application ("GlosSIConfig") handling shortcut ("GlosSITarget") creation and their addition to Steam.

GloSC got mentioned from Valve in the Steam client beta change log on the 9. of January

GloSC/GlosSI is not affiliated with Valve, Steam, or any of their partners.

GlosSI is built using Qt 6.2 and a fork of SFML for drawing the overlay

The system wide Xbox-Controller works via ViGEm Device Hiding via HidHide
