GlosSI [GloSC] 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
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.
En los foros de GoG hablan de usar el lancher GALAXY 2, auque parece ser mejor opcion GlosSI en le tema de usar el control de steam en juegos fuera de steam.
Yo utilizo reWASD para que todos los mandos que conecto al PC, da igual de que sean, se comporten como si fueran de Xbox. Es de pago, pero no es caro y ya te digo, sirve para TODO.
