GloSC VS steamgriddb-manager

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.

SteamGridDbManager

Sure you can do that on Steam either as adding any game as non-Steam game from menu or use tools like this to do that.

You should really use steamgriddb manager to set consistent images that's what ROMs ce done and it looks great https://www.steamgriddb.com/manager

Steam already has that feature way way before even others were a thing back then. It's https://help.steampowered.com/en/faqs/view/4B8B-9697-2338-40EC and to do this in a shortcut, you can use https://www.steamgriddb.com/manager to import your "installed" games from other launchers.

The tool https://github.com/SteamGridDB/steamgriddb-manager

Steamgriddb manager? just googled it, https://www.steamgriddb.com/manager found that it is not under development? I didn't plan to replace it, but I can imagine that there is probably some overlap.

Have you tried SteamGrid DB Manager ? It has worked to import games for Epic and other launchers before. I have Battlefront II from Epic sure also and i think I used that to import it.

steam grid db manager

for Epic and the rest: I would use https://www.steamgriddb.com/manager (or https://github.com/WombatFromHell/OriginSteamOverlayLauncher) for this sort of stuff...but it may be reliable for certain games (aka Call of Duty Warzone).

There is also this manager which is made for many launchers to be easy to import into steam. I've never used it personally and don't know if it's made for steam input in mind.
