Initial release for Japanese PC version.


Many of these can be turned on and off individually.

Game bug fixes

The original game release has several technical issues, such as broken lipsync and crashes when pausing right before voiced lines. We’ve fixed all we could track down.

Script fixes

From typos to mistranslations, we’ve fixed mistakes ranging from large to small—for a total of over 1,600 lines changed. Some of them were tiny enough that most people would probably skim past without realizing, while others were grossly obvious or confusing and were serious impediments to an immersive reading experience.

Consistency fixes

There were a number of terms in CHAOS;CHILD, such as names of people, objects, and products, which were translated differently in previous localizations and official media. This patch optionally replaces all inconsistent terminology with the translations used in previous titles (primarily STEINS;GATE’s localization), as well as swapping the name order to Japanese (e.g. “Takumi Nishijo” → “Nishijou Takumi”).

Typography improvements

Text box and backlog text is displayed in a nicer font, and issues such as text hanging off the edge of the text box have been fixed.


Adds text to various voice-only lines and cutscenes, including several important lines which previously had no translation. Additionally, there are optional karaoke subs added to openings and endings.

Translated CGs

Includes translated versions of most CGs with text. The original title had some untranslated CGs (including an untranslated map that made it impossible to finish the game without a guide), as well as parts of some CGs which were even machine-translated, and we translated and re-edited these images from scratch in 1080p (as opposed to upscaling from 540p Vita CGs or keeping the Steam versions). Over 200 images were modified in some way.

High quality FMV audio

Many video files in the game (openings, endings, and several cutscenes) have very low-quality audio due to poor compression. This patch replaces low-quality tracks with higher-quality versions.

UI improvements

Much of the system/menu text has been re-translated for comprehensibility. Backlog highlights have been adjusted to suit multi-line text.


Installation instructions

  1. ↓ Download the installer. You want CCPatch-v<version>-Setup.zip, not the source code.
  2. Extract the archive somewhere on your hard drive, not in your game directory.
  3. Go to the newly created CCPatch-v<version>-Setup folder and run CCPatch-Installer.exe. Warning: Has sound.
  4. After you click Finish and the installer closes, you can delete the CCPatch-v<version>-Setup folder.


If you’re having a problem not covered here, please ask us on Discord about it.

Note: The game requires the latest DirectX 9.0c redistributable (having a higher version of DirectX installed is not sufficient). If the game fails to run for you, install DirectX 9. (Steam should take care of this for you, but we’re leaving it here just in case.)

Game/launcher fails to start from Steam

You can try starting the launcher from the desktop/start menu shortcut (if you created one during the installation) or by directly running LauncherC0.exe from the game directory (right click CHAOS;CHILD in your Steam library, PropertiesLocal FilesBrowse Local Files…). Make sure you’re logged into Steam, though.

Phantom inputs make the game impossible to control (menu selections automatically go up)

On some systems the game detects false controller inputs (mostly on Linux, but we’ve heard this from Windows users as well).

In the launcher, click More Settings if you haven’t already, go to the Controller tab, select a different controller if you get multiple options or just disable controller input altogether by unchecking Enable.
