I know it's for Steam Deck, what I'm interested in knowing is whether the games work with Aurora only in desktop mode or also in big picture mode
Oh, you meant gaming mode as Big Picture Mode is a completely different thing. Yes, it will. But not 100% of the time. It does pretty much work 99% of the time in desktop mode.
So I downloaded and setup the tool for the first time. When i open it say aurora and game status stopped. Did I do something wrong or miss a step?
If you launch the Steamdeck Tool launcher by itself it should say stopped for both. It will only change when you launch a game.
I haven't been able to get Hades or Have a Nice Death with any combination of Proton. Does it have something to do with these being Linux native? Or has anyone had luck getting these to run?
I just answered about Hades not too long ago.

I tried changing these settings but that did not seem to fix the issue. When it occurs I can switch freely between windows but while the cheat happens screen loads the options can not be clicked. Mainly the issues have been with the resident evil games
RE2 - worked at one point, but now I cannot use the cheat happens interface.
RE4 (2022) - Aurora does not detect the game at all. Loading it manually via mobile does not seem to be successful either.
Its definitely a window issue. Have you tried on desktop mode?
