OriginSteamOverlayLauncher VS GloSC

https://github.com/WombatFromHell/OriginSteamOverlayLauncher/releases/download/v1.09f/OriginSteamOverlayLauncher-v1.09f.zip Download and unpack this. Follow instructions on readme file.

I'd use https://github.com/WombatFromHell/OriginSteamOverlayLauncher, works great for battle.net games.

Either GlosSI or OSOL are likely what you're looking for.

You'll probably want to ask on r/WindowsOnDeck to get a better response, but I think there are two basic routes to try here. One is to try to force the Steam overlay to work with something like GloSSI or OSOL. The other is to use 3rd party drivers for the Deck's controls.

I think part of the problem is the launcher. It seems that whenever I launch any .exe of the trilogy (ME1-3 themselves or the launcher .exe) while I can load into the launcher, controller input does not work. I am only able to navigate the menus and the game itself by switching to mouse mode via the back button on my controller and then using the right stick to navigate. This, naturally, is not functional for actually playing the game. I've tried dozens of fixes now, from adding different .exes, using the .exes with the OriginSteamOverlayLauncher, launching Origin itself through Steam and then launching the game from origin within steam, starting the programs from the host and client in different orders, etc. I've run steam and origin in compatibility modes, as admin, and using a number of secondary launchers and mods. Nothing works. The game simply won't recognize the controller.

You can use osol to avoid this .

Try OSOL and look here for more detailed instructions. I hope this helps, and happy gaming

That's when you start breaking out tools like GloSSI and OSOL to try to get unruly games in line. I've had to use one or the other get Steam Input to work with Amazon Luna running through Microsoft Edge, Star Wars Jedi: Fallen order on Origin, and Far Cry 4 on Ubisoft's launcher. None of those worked when simply added to Steam normally, but were made to work with extra tools.

OSOL Origin Steam Overlay Launcher (works for more than just Origin)

For GTA V (I have the "Epic Store" version), I just added the "Rockstar Launcher" as a "Non-steam game" and it worked with no issues. I had to use GloSC for Genshin Impact and other games.

I had an issue where my PC viewed the backbone as keyboard inputs, so I had to use this GitHub project and it works flawlessly now. https://github.com/Alia5/GloSC I just do a blank one, not linked to any games, and launch it on my PC via Steam before I plan on streaming on my phone.

GloSC

You could try this https://github.com/csutorasa/XOutput that seems to work like xc360 but works with UWP, or maybe https://alia5.github.io/GloSC/, to open UWP apps trough steam and use the steam controler interface to assign the buttons.

I think you might need this to get it to work https://alia5.github.io/GloSC/

I mean the SC is not tied to Steam. Lots of games I play with the SC I start as a non-steam game from Steam and it works fine. Also https://alia5.github.io/GloSC/

I just setup Steam link for the first time, and was disappointed to find that when I launched an Origin game, my controller would default to it's Desktop Mode inputs. Same thing happened for an Epic game. I've seen people suggest various third party software (OSOL, GloSC), but what I did was remap Desktop Mode so that instead of RT being click, LT right click, LS the mouse cusor, etc...... RT was RT, LT was LT, LS was LS, A was A, B was B, and so on.
