This Guide will be published in a functional state, meaning you can follow the steps and resolve the OP/ED issues, but as of 08/19/25 it is not what I would call "Complete". Basically I want to add more photos for each step & decide if I want a Script to automate most of this process.

Either way..

(The fixes are 100% real, it's just not as Pretty or Well done, for my standards.)

This will work across Linux Distributions regardless § requires light Terminal usage.


Steam Deck / SteamOS

1. Steam

2. Desktop Mode

3. ProtonPlus - Custom Proton Manager[dl.flathub.org]

4. GE-Proton10-12: - The Script will automatically install this version -

......I'm debating this ↗️↗️↗️ - so for now just...

• Use ProtonPlus to install GE-Proton10-12

5. Protontricks: - Click for Installer -[dl.flathub.org]

6. Sh Script for Auto-Installation: - - Click for Script -[raw.githubusercontent.com]

(Right Click the Page & "Save as")

6(a) Save the Script(codec.sh) to..

Steam Deck:
Linux/Other:
$HOME - Assumes your home location regardless of (user)name, you can type this manually into the file browser and it will take you to /home/Username/Downloads.

---

7. Guide Requires Game to be installed on Internal Storage

- Estimated Guide Install: Average 2-6 minutes(+/-) | Hardware Dependent

---

Desktop Mode? - 1(a). You will need to know how to enter Desktop Mode & at the very least know how to open Steam & Use The File Explorer(Dolphin)

---

Why Internal Storage? 2(a) - It's not required, this is solely to streamline the tutorial and reduce how much I have to type I have to type. Adding an SD Card into the mix will add additional steps that may confuse some readers.. Follow-up at another time.

• Open Protontricks
  
  - Select GINKA ----> Next Screen | Choose: "Select the Default Prefix"
  
  
  
  
• Select the Following:
  
  Change Settings ---> "win11"
  
  
  (This is going to be REALLY fast, Proceed to the Next Step)

• Select Run a Commandline Shell (for debugging)
  
  
  
  
• Type the Following
  
  (If you have a keyboard you can use "Shift + Insert" to paste - you can also bind Steam Input to do this in Desktop Mode on SteamOS)
  
  
  sh $HOME/Downloads/codec.sh wmp11 quartz2 lavfilters
  
  (You will have to manually type this, copying & pasting isn't allowed in the debugging shell, so long as you place codec.sh in $HOME/Downloads it will recognize it.)
  
  Press "Enter" - and the script will get to work. - And just like that...
  
  

So yes if you made it this far you are done & everything should be working 100%.

*Should

I will include troubleshooting steps and other things, but for right now I just want to get the guide out there, bc I've been sitting on this for waaaaaay too long, I'll fix up the guide and make it look pretty by the end of the week.

But if you made it this far thank you for your time & I hope it helped you out.
