----- This guide was made for Primarily Steam Deck users on SteamOS -----

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

Steam Deck / SteamOS

1. Steam

2. Desktop Mode

3. GE-Proton8-21: - The Script will automatically install this version -

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

5. Sh Script for Auto-Installation: - - Click for Script -[codeberg.org]

(Right Click the Page & "Save as")

---

---

4(a) Save the Script(sck-in.sh) to..

---

---

---

6. Guide Requires Game to be installed on Internal Storage

- Estimated Guide Install: Average 4-8 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.

(If you've followed the prerequisites above you should be in Desktop Mode already.

• Open Terminal(Named: "Konsole")

  ---

  
  

  ---

  
  
• Use the Application Guide to find "Konsole" & Open it.
  

  ---

  

  ---

  
  
• Use "L2" or Right Mouse Click Action to Copy/Paste the Following into the Terminal(Konsole) in Sequential Order:
  
  
  
  chmod +x sck-in.sh && ./sck-in.sh
  
  
• Press "Enter" or the "A" Button to apply information to the Terminal
  
  
  
  (If this fails for any reason, try dragging the .sh file into the terminal & press "A" / Enter)
  
  
  
• Our Files have now been installed - Next Step

(God I don't want to do this)

1. Select Sickly Days & Summer Traces

Select the "Default Wine Prefix" when it asks.

2. Go to "winecfg"


3. Check Windows Version

• Proton may in some instances, default winecfg to an older & incompatible version of Windows such as Windows 2003, XP, etc.
  
  
• Ensure it is no lower than Windows 10/11.
  
  {This is crucial}
  
  
  4. Under Library add the following overrides:
  
  
  d2d1
  
  
  qasf
  
  
  quartz
  
  Don't forget to click "Apply" before leaving winecfg
  
  (If you click the down-facing arrow, it will auto-fill in the words as you type)
  
  On-to the next part...

(Hestia-sama, have mercy on my soul...)

1. Select Install a Windows DLL or component

2. Install the following Dependencies:

• DO NOT INSTALL ALL AT ONCE
  
  - Install each dependency one at a time, in that order to ensure everything is installed properly & Protontricks does not exactly tell you when it finishes until it's completely done installing, this will keep you engaged & prevent you from guessing if protontricks failed, hanged or stopped working.
  
  Proceed to the next step.

1. Select Run a commandline shell (for debugging)


2. Type The Following:




- This is case sensitive, thus type exactly as written - cannot copy/paste this -

(Once that's done, you can close the Protontricks Program)

(Movies: OP/ED Should now work)

1. Go to Game Properties via Steam Client:


2. Add the following to the Launch Options..

Access Violation should no longer appear!

This is an issue within how WINE-Proton handles KiriKiri Engine visual novels, which I presumed that Valve fixed bc there was a time where all KirKiri VNs were busted on SteamOS(2 months ago), but this specific issue seems mostly steamed from the missing .dll file that's needed.

It is also modified to work better w/Linux & cause less issues.

This guide is not entirely my own, I did add my own additional fixes & automation in the process, but there are many creditors who made this possible. Zero Fox[bugs.winehq.org] who made the first bug report about this(two months ago) directly to the WINE Developers who resolved any concerns on their end.

And to the guide on VNWiki[www.vnwiki.xyz] which has a list of all creditors who made this guide ultimately possible.

Not Least: b-fission[github.com]

who modified the missing .dll file & created the codec.sh script that installs needed codecs & overrides WINEPREFIXES to ensure compatibility.

codec.sh is the sole reason I am able to make OP/EDs work on GE-Proton10+, where as after GE-Proton8-21 OP/EDs were broken for KiriKiri Games using methods such as the GINKA Guide

For making everything easy to access, now I'm just going step further by improving automation & accessibility for the Average Steam User.

Additional Proof that this guide does work:


Hopefully this made the fix easier to access & resolve than existing methods.

I'm going to sleep now, give the guide a rating or i'm never doing this again(haha...)

okokokok.. Why are you yelling?!??

Anyways..

• Install GE-Proton10-12
  
  - Go to Properties ---> Change Proton Compatibility to ↖️↖️↖️
  
  - Preferably delete the existing prefix & open start the Visual Novel in Steam to automatically create a fresh / new(Proton Prefix) one w/GE-Proton10-12 includes fixes
  
  
• Follow the Guide up to STEP 4
  
  - When you get to the Debugging shell Type the following:
  
  
  sh $HOME/Downloads/codec.sh wmp11 quartz2 lavfilters
  
  - And that's it. Now your KiriKiri Engine Visual Novel works with GE-Proton10-12
  
  Using GE-Proton8-21 is faster to complete & requires less typing, but you can get Proton 10 working with this VN - the custom d2d1.dll is holding this VN together on Linux for sure, thanks again fission-b.
