Controller button prompts would not appear. Game displays keyboard buttons instead.
Game works no problem out of the box.
As the users below me said, you really have no reason not to play CHAOS;CHILD without the Committee of Zero patch. Don't play the game without it. Just get it.
IF YOUR GAME WILL NOT LAUNCH AND THE ERROR CODE STATES THAT THERE IS AN ERROR IMPORTING SETUP FILES: I experienced a weird problem after installing the CoZ patch. When pressing start game from the launcher, the game would immediately crash with the following error message: "There is an error importing setup files", and google/reddit/discord was really unhelpful.
I thought it was a CoZ problem at first, but it seems to be a common problem with japanese-made visual novels (the Science Adventure series has this problem). According to Google, on windows, it's generally a UTF-8 encoding problem, but Steam Deck uses UTF-8 encoding by default.
I tried all the fixes listed on the Steam Community discussion posts, including deleting config.dat in documents. THEY DO NOT WORK ON THE STEAM DECK. Some will even tell you to do something to your Steam Deck root folders. PLEASE DO NOT ALTER YOUR ROOT FOLDERS.
After uninstalling the game and deleting all CoZ files in the game folder, I reinstalled the game, reinstalled the CoZ patch, and it worked. I'm not sure how to recreate this issue, but hopefully this helps someone that has the same problem in the future.
use the Committee of Zero patch to get the full experience for this game, the github page polyversal-coz-linux-patcher helps a lot
This game may just work out of the box, but it's recommend to install the Committe of Zero patch, it's necessary due to a horribly bad localization. Installing the CoZ patch isn't streamline since it's a Windows program, but if you can follow some readmes you'll be fine.
The CoZ patch needs a special Proton version (ProtonGE-anonymouscode) this does require the terminal to install as Protonup-QT won't see it, but it was all copy and paste from the github readme and this is the only time you need the terminal. It also needs a bash script for the install.
Time of setup of the already installed game including downloading 2 VERY SLOW github files was about 30 mins. The game has no issues once this is done. It starts, my cloud saves work and the audio, video and text is all fine. I wouldn't rate this game "Platnium" with this kind of inital setup, it wasn't hard, but it was time consuming, requiring reading 3 readmes, 2 github files, along with the patch itself and it required the terminal. So this was far from just having to switch a Proton version and adding a command line. But once you got it setup it's a Platnium experience.'
WINEDLLOVERRIDES="dinput=n,b" %command%
The game worked flawlessly with and without the Committee of Zero improvement patch (which you should be using). This patch will install perfectly fine, and if you just installed the game onto one device and are not moving i.e. a microSD card between devices, then none the below applies. Everything is green, go ahead and enjoy! But if you're moving the game install (i.e. on an external drive or a microSD card), there is an extra step required.
- The CoZ patch does two things during installation: Moving its files into the game files (including the launcher), and exporting a Wine DLL override for dinput8 onto the prefix when it detects that it's running under Wine. However if you put the game onto a microSD card or external drive, and then try to run it on another Steam Deck or on a PC, the prefix will get re-created and thus will not have this DLL override that was applied when the patch was installed. The impact of this is that the CoZ launcher will show up, but the patch itself will not be loaded (evidenced immediately on starting the game by the untranslated logo on the main menu, different font, no mouse support). So even though the CoZ launcher will load and be used to start the game, the patch content itself will not be loaded!
- To fix this you can just manually export the DLL override in the launch options though, with "WINEDLLOVERRIDES="dinput8=n,b" %command%" (without the quotes). Reinstalling the patch wiill also work, but this may be more straightforward.
- There are other ways to set the DLL overrides, such as by manually setting the override in Winecfg or editing the prefix regisitry (which Winecfg does), so use your preferred method.
- This step is also required if you choose to manually install the patch by dragging the patch files over into the game files without using the CoZ installer.
If you install the patch on a fresh game install, none of this applies and it all works OOTB! But if you install it on a microSD card or SSD that you move between devices, you will need to set the DLL override so that the patch can be loaded. That's it!
Try patch from Committee of Zero when launcher failed.
Flawless.
I did not test for very long, since I've already 100%d the game some years ago.
Shows the keyboard prompts rather than gamepad prompts, but otherwise works great so far.
I used GE Proton to use FSR before it landed in mainline proton.
Works perfectly well out of the box
I used proton 6.3-6 but other versions would probably also work. AFAIR I did not come across any kind of issues/crashes.
Just make sure to install the committee of zero patch. It improves translation. They also have Linux installation instructions for the patch on their website.
Installed the Committee of Zero patch
the latest proton versions have slow video playback
Proton FSHack makes it a more enjoyable experience at high resolutions(1440p+) than windows since the game only goes up to 1080p and won't screw up the scaling unlike windows.
Work perfectly out of the box except for movies. Xbox controller is recognized and works.
Movies make fps go down to 10
Recomiendo FUERTEMENTE la retraducción al inglés, corrige muchos errores y para conseguir el final verdadero es VITAL ya que cierto elemento está en japonés y va a ser mas difícil sacarlo. http://sonome.dareno.me/projects/cc-linux.html
After fixing the game not launching problem, the game starts and then runs without issues with the patch installed.

It seems that by default Steam calls the boot.bat file, which does not work on Linux.
Committee of Zero patch fixes this by making Steam launch the .exe file instead. If for some reason you won't install the patch (you should really install it as it improves the game in many ways), ran these commands in the game's install folder to fix the issue: mv boot.bat old_boot.bat ln -s launcher.exe boot.bat And you also might need to set the game's launch options to "EN" as noted by others.
Debes usar Proton 4.11-12, si no lo usas el sonido no va bien. Recomiendo FUERTEMENTE la retraducción al inglés, corrige muchos errores y para conseguir el final verdadero es VITAL ya que cierto elemento está en japonés y va a ser mas difícil sacarlo. Simplemente sigue esta guía tal como lo dice, eso sí, luego usa Proton 4.11-12 En esa web hay una guía para pasartelo al 100% sin spoilers. http://sonome.dareno.me/projects/chaoschild-steam.html
Runs about perfectly. Don't tried without Zero patch though
Sometimes mouse motion is not capturing. Need to alt tab the game
Use the Committee of Zero's patch to get the game working, along with English-translated visuals, better fonts and translations:

If you get glitched graphics, try reinstalling the game on the same partition you have your main Steam library on. I don't know why, but this helped in my case, even though my side library is using Ext4 as its filesystem too, so it wasn't an NTFS issue.
Works perfectly out of the box.
With the Committee of Zero patch (which is HIGHLY recommended), the game works flawlessly. I beat the game in 42h without any problems whatsoever.
I think everything works (Controller support wasn't tested), I installed the Committee of 0 patch and that one works too.
Unknown(2+ hours with Proton)Controller is working (Xbox One Controller). As others have mentioned, I had to rename launcher.exe to boot.bat and set launch options to "EN" to start the game. Using the improvement patch also worked.
Unknown(2+ hours with Proton)UnknownUnder 4.2-9 the game won't start even after trying the launcher/boot changes. However, launching with Proton 3.16-9 did work.

everything works but crash happens occasionally. to get it running, go to installation folder, rename Launcher.exe to boot.bat and set launch options to "EN".
Flawless - everything works perfectly, including audio, alt-tabbing, fullscreen support with a resolution different than native. Controller support hasn't been tested. Committee of Zero's improvement patch is recommended and it supports Linux: https://sonome.dareno.me/projects/cc-linux.html
Same problem at launch as with Steins;Gate 0. Copy Launcher.exe as Boot.bat and you won't have a problem. Also there may be some sound issues (sync with character motion, quality of sound), but they are not critical. Game performs great.
Unknown(< 15 minutes with Proton)Works almost flawless. Go to the Chaos;Child folder and rename launcher.exe to boot.bat. Go to the game's Launch Options and set it to 'EN'. Game should run without issue.
