Can't find config file on Steamdeck

Hi,

I have installed RPCS3 on my SteamDeck and thankfully found the initial setup guidance invaluable.

However, I am unable to get the gamepad controllers to work. 

I am trying to use a Stadia Controller and an Xbox Controller. The Stadia controller analogue sticks aren't centered in the "Pads" and when I navigate to ~/.config/ there is no rpcs3 folder in there to modify, nevermind a "evdev_positive_axis.yml" file.

I have searched for similar folders and files to no success, and I even created this folder in the ".config" folder but this didn't work either.

What am I missing?

Thanks in advancce.
