What does the SD tool say for Pac-Man? Have you tried choosing a different proton version?
I've tried to choose another version of Proton via the SD Tool Edit Game Settings tab. I tried to force the Aurora window to the foreground and was given this message: Failed to force Aurora to foreground; Command execution canceled. Underlying process (bash#19847) was forcefully terminated.
I dont know what Decky is. The minimum Proton I have installed is 8.0 and I also have installed Proton Experimental. I did not choose any specific Proton myself, SD tool is using Proton Experimental by default. And all I can say is that on a default Steamdeck, launching Aurora together with the game Pac-Man using SD tool works out of the box.
Whatever is causing it to fail on your end its not the SD tool nor a setting of the SD tool. Either its Proton 6.3, I think you can uninstall it from your steam library it should be under "tools" or something. Or its "Decky" or anything else.
Thanks for the feedback.
I appreciate your help, 0x90.
I wanted to mention that I have disabled Aurora with games that forced keyboard inputs and now I can use the Steam Deck inputs instead of keyboard inputs with the game. Whenever I launch the SD Tool, the virtual keyboard appears when Aurora launches. In the past, I was able to use the SD Tool and was not required to use keyboard inputs. I am unsure what is causing this issue.
I will keep troubleshooting as time allows, and report my findings.
