Guide to Play on the Steam Deck Properly

Step 1. Installing the Game

Go to Psychonauts in your steam library and open up properties, then go to Compatibility and hit the checkbox. Change the dropdown to Proton 5.13-6 (If the dropdown doesn’t show up exit and go back to properties.).

Go to the controller settings for Psychonauts and change the control layout to “Polo’s Better Controls” (You’ll probably have to scroll down quite a bit to find it.).

Make sure the game runs at this point and set the graphics in game to 1280×800 and check all the boxes. Also bind your controls in game based off of how the controls are labeled on the controller guide (Picture provided below).

Step 2. Modding the Game

Go into Desktop Mode.

Download this Zip File and extract it into your Psychonauts folder, overwriting every file if it asks you to. This Zip file will change the keyboard prompts to controller prompts (This is a very hacky workaround I used which is why the actual inputs are really odd.).

Download the Psychonauts Widescreen Fix and also extract it into the Psychonauts folder. Go into the scripts folder and edit the ini file inside it. Change the WidescreenHudOffset from 100 to 111.111 so that way it will scale the elements properly for 16:10.

Go back to Gaming Mode.

Go to properties and add this to Launch Options:

WINEDLLOVERRIDES="dinput8.dll=n,b" %command%

Step 3. Enjoy!

Psychonauts should now 100% work on Steam Deck with proper widescreen scaling and controller prompts!
