CHAOS;HEAD NOAH: the mindbending, unforgettable opening act to one of the most popular Visual Novel franchises out there—the Science Adventure series. It’s the definitive edition of the CHAOS;HEAD story, featuring a number of fascinating character routes that expand on the original and its characters. And we’ve been working on it for… a very long time.

And it’s finally here.

Featuring a fully uncensored experience, over 150 translated CGs, countless bug fixes, as well as an entire original translation of the game, this is our most ambitious project to date. In the past, we’ve only had our patches available for English audiences on PC, but for CHAOS;HEAD NOAH, we’re not stopping there. Our patch is available for Steam, Steam Deck, GOG, Nintendo Switch*, and in both English and Japanese. See below for a full list of features.

And now, without further ado…

It’s time to find the blue.

Features

Fully Translated from the Ground Up

Over six years in the making, the biggest feature this patch provides is our very own translation. Ever since our head translator opened up the first script in April 2017, we’ve been toiling over each and every line in order to best represent these intriguing characters and the sweeping story that surrounds them. We’ve lived and breathed these scripts for years now, all so we can ensure that you, the readers, will feel the same way we did when we read it for the first time so long ago.

From scenes of grief and tragedy, to lighthearted slice-of-life, to spine-tingling horror, we’ve worked hard to make sure our translation will provide you with the best possible English-speaking experience for this 2009 classic.

We’ve got a little more to say in regard to why we felt it necessary to replace the translation, if you’re interested. You can find it right here.

Consistency

The Science Adventure universe is a rich setting filled with many diverse sci-fi concepts, forming an immersive, interconnected world. Of course, in order for this to work, the connections between games rely on having the same names being used for the same things. Unfortunately, in the official English releases, that’s not exactly the case. Terminology is translated inconsistently, references are constantly missed… It’s clear that these translations were made without context of the greater series.

Our patch rectifies this. Ranging from NOAH’s sequel, CHAOS;HEAD Love Chu☆Chu! to the latest SciADV entry, ANONYMOUS;CODE, we’ve made sure to restore every little connection from game to game to maintain the intended experience for not just NOAH, but the entire Science Adventure series.

Decensored Content

When NOAH was ported to PSP, a great deal of content was cut in order to lower the age rating. And, unfortunately, the Nintendo Switch and PC releases are based on this censored script. Eleven scenes throughout the game had lines completely deleted, and one route in particular had a whopping 500-line scene erased entirely! This scene is vital to the game’s central mystery, making the exclusion all the more damaging to the experience.

In our patch, however, we’ve added back every last bit of the removed content—restoring the presentation of the original Xbox 360 release.

Furthermore, we’ve restored full functionality for the Lingerie Conversion Patch DLC. This includes Seira’s alternate outfit, which was removed in the official localized release.

Translated Images

From CGs to BGs, nearly every single image in the game with Japanese text has been translated into English. Over 150 images have been painstakingly cleaned, redrawn, and typeset for this patch.

Translated Videos and Audio

Every opening and ending song in the game has been translated—all 13 of them. We’ve included optional karaoke subtitles for each one, with the ability to select between Japanese & English song subtitles, Japanese-only subtitles, or English-only subtitles.

Also, a number of lines in the game are audio-only and have no associated text. We have provided subtitles so that these lines are understandable to an English audience.

Finally, to ensure that all the staff who worked on this game get their fair acknowledgement, we’ve also translated the entirety of the game’s credits to English.

Bug Fixes

The Switch/PC ports are plagued with numerous technical issues. Videos refusing to play, sprites not showing, incorrect images being displayed, certain visual effects and menus being entirely broken… We’ve fixed every single issue that we could track down.

For example, the skip feature is notoriously broken, with it constantly stopping every other line. We’ve restored it to its normal functionality so you can get to the game’s many endings far quicker.**

Additionally, the SHORTCUT menu, which allows you to skip between chapters after the Common Route is complete, was left unfinished by MAGES. We’ve fixed up and completed the implementation of this menu, so it is now fully functional.

Typography improvements

We’ve completely rewritten the text rendering engine to provide a better reading experience. All text is now displayed in an easier-to-read font with better formatting, plus new features implemented such as italics.

Additional Features

A number of unlock conditions for certain extras have been changed in order to better replicate the experience of the uncut Xbox 360 and PS Vita versions.

We’ve included one last surprise after the credits roll. Keep your eyes peeled for it!

Save Game Compatibility

Can be installed over every version of the game without breaking existing saves.

Troubleshooting

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

Note: The game uses components from the latest DirectX End-User Runtimes (you may not have these even if you have the right DirectX version). If the game fails to run for you, install DirectX End-User Runtimes. (Steam should take care of this for you, but we’re leaving it here just in case.)

Also, for the patch to work, you might need to install Visual C++ Redistributable (64-bit version, vc_redist.x64.exe - regardless of your system) and try again.

Installer shows an error about MSVCP140_1.dll

Install Visual C++ Redistributable (32-bit version, vc_redist.x86.exe - regardless of your system) and try again.

Installer shows an error about api-ms-win-crt-runtime-l1-1-0.dll

Update Windows. You may need to install the Visual C++ Redistributable again afterwards (file above) - use “Repair” when prompted.

*(Nintendo Switch version requires custom firmware. Compatible with JP, US, and EU copies.) **The skip function will still be broken on pre-existing saves, as the save data is used to keep track of which lines have been read before. Skip through the game at least once to remedy this issue.
