Setup Instructions

Video walkthrough

Alternative Text walkthrough on how to get just English


  • First of all, you don't need to extract this into a specific game directory. The patcher can run from any directory.
  • Run thcrap.exe and follow the instructions to create your patch configuration.
  • You'll end up with a .js file (the configuration itself) as well as links to start every Touhou game found on your system with this configuration. Note that thcrap does not modify any existing Touhou installation on your system.


  1. Download Patch and unzip (directory does not have to be specified; feel free to place wherever you want)
  2. Run thcrap to find the Touhou games.
  3. Pick your languages.
    Yes, plural. If you understand English to some degree, we recommend to always include lang_en at the bottom, and your native language on top of that. Read more on the topic of patch stacking here.
  4. Wait for the downloads to occur.
  5. In the browsing dialog, select the path where your Touhou games are located, or hit Cancel to search your whole system.
  6. Select your preferred version out of the Touhou games with multiple versions on your system.
  7. Use shortcuts.
  8. Enjoy.

Running on top of vpatch

This is possible as of the 2013-10-25 build. Due to the DLL-centric design of vpatch, thcrap doesn't automate this yet, so this requires a few manual steps for now:

  1. If you don't have vpatch yet, please download it from Touhou Wiki or from the author's download page.
  2. Configure your patch stack as usual. If you have multiple versions of the games installed, it is merely important to choose the correct directory at this point.
  3. Open the generated games.js in a plaintext editor, and replace the game's .exe file names with vpatch.exe (or whatever the local vpatch executable is called).
  4. Starting the games through the shortcuts will then launch thcrap, vpatch and the game itself. thcrap will automatically enable support for Japanese characters and file names, so AppLocale is not required (yes, not even for 東方紅魔郷.exe).

HALP! My Icon th06.png Embodiment of Scarlet Devil runs like a Tengu jet fighter on steroids!!

Getting Touhou 06 to run on Windows 10 requires vpatch.

  1. Download this complete vpatch th06 for thcrap package. It includes vpatch (rev4) and our modified Unicode vpatch DLL.
  2. Extract the zip contents into your EoSD directory.
  3. If your EoSD directory already contains a file named vpatch_th06.dll, please remove it. You will only need vpatch_th06_unicode.dll.
  4. If your game executable is named th06.exe, rename it to 東方紅魔郷.exe. This is necessary because vpatch.exe will expect to find only this file. If you only have th06e.exe and neither 東方紅魔郷.exe or th06.exe, you are using the modified English static patch. We highly recommend that you use a proper Japanese original 1.02h version instead.
  5. Open thcrap\config\games.js with a text editor and make th06 point to vpatch.exe instead of the game executable.
  6. If you encounter a lot of screen tearing, open vpatch.ini in a text editor and set vsync = 0 to vsync = 1.


File Output

This will dump all the original, unpatched files loaded by a game as it runs.


  1. Locate the .js file that is created when you run thcrap.exe (this would be whatever you named your shortcuts, so if you called your shortcut "en" then the .js file will also be called en.js).
  2. Open it with your text editor (notepad, editpadpro, etc)
  3. Change "dat_dump": false to either
  • "dat_dump": true - this will output files to wherever you placed your original game, in a folder called dat
  • "dat_dump": "C:/name/to/dump/path/" - this will output files into the given directory.

Then, run the shortcut.

Steam integration

We'd actually need a new guide how to do this at this place!


How to debug a game crash, freeze, or other issue unrelated to translation

A complete patch setup is made up of a number of individual parts, any one of which will be responsible for the issue you're experiencing. If possible, please try to pin down the cause before reporting an issue to us.

  • Does the issue appear in the original, unpatched game?
While thcrap fixes some of the bugs in the original games as part of its patch support, we sadly don't have the capacities to fix all of them, as we are mostly busy with thcrap's own bugs and features, first and foremost. Still, please report the issue, maybe it is trivial enough that one of our developers can look at it and fix it fairly quickly.
  • Try removing patches from your stack, one by one, starting at the bottom.
  • To do this, edit the run configuration .js file generated by thcrap in a plaintext editor like Notepad.
For example, if you only selected the English translation, you'd edit en.js (or whatever you've named it). You'd first remove the
, { "archive": "thpatch/lang_en/" }
section, then check whether that fixed your error, using your existing shortcuts or launchers. If it didn't, remove the next patch, and so on.
If you are unfamiliar with JSON, use JSONLint or JSON Formatter to verify the syntax of your edited file. This site also gives you helpful error messages if you e.g. left a comma at the end of the "patches" section.
  • If necessary, repeat this until you have no patches left. Note that running thcrap with no patches is still different from running the original, unpatched game. It still applies the game-independent features of thcrap, like its locale independence code or its propagation to child processes, onto the game, which might be the cause of your bug.
If the bug still appears with no patches, you're done. But if you could identify a patch that caused your issue:
  • Temporarily delete or rename thcrap_update.dll in the thcrap directory in order to disable automatic updates.
  • Look at thcrap_log.txt and check which files of that patch are actually loaded by the game. These are indicated by lines beginning with a + .
  • Delete those files one by one, until the bug doesn't appear any more.
These files will be re-downloaded once you restore thcrap_update.dll.

Known issues

My game isn't recognized by the configuration tool, and no shortcut is created

If that game happens to be Icon th075.png Immaterial and Missing Power: thcrap does not support it yet.

If you're on Linux or MacOS with Wine, there seems to be a bug when when the game is in a subfolder of the selected folder (which happens when you add your folder with all your games in it). If this happens, you'll need to use the "Find games in a specific folder..." button to add each game one by one.

Otherwise, please post the game's executable on either discord.png Discord or irc.png our IRC channel #thcrap on We'll see what we can do.


Untranslated Japanese text appears blank on Wine

This is a bug in Wine, and has not been fixed as of October 2017. Even if Japanese fonts are installed and work as intended on an unpatched game, Wine's font substitution is not sophisticated enough yet to use glyphs from these fonts in case the currently selected font (Touhou Biolinum for Latin script languages) does not contain Japanese glyphs.

Dialogue does not fit in text box

Unfortunately, ZUN's engine has never been able to do automatic line breaks, and we don't want to combat this by having the wiki parser guess where to put a line break. This means that all of the line breaks have to be done manually.

If you see such a line, just log in, look for the corresponding page and split it yourself. If it's a third-party patch, then e-mail the project leader about the issue, or tell them on GitHub or wherever they host their patch.


Japanese text error
The ZUN Mutex

The error to the right is shown whenever a Touhou game is started and there is another Touhou game process active, meaning that you cannot run two Touhou games at the same time. Check Task Manager for any zombie processes and kill them if necessary.

Some translations are incomplete or missing

Check the corresponding text page on this site; most likely, the translations there have not been finished yet.

Patch configuration

Why does Patch X not work with Patch Y?

When you are using multiple patches, the order is important. For example one may want to use Gamer251's Mima patch for the Mima sprite and dialog, the Alphes patch for Alphes-style art, and our English patch to have the rest of the game translated to English. If one was to use the Mima patch first, then the Alphes patch, then the English one, they would discover that while the other patches were applied, the English title screen was applied to the Mima's custom title. So for a typical patch selection, the correct way to select a patch if it's not already not added for you (as seen with Nazeo's gangster patch) is using the main language first, then the mod.

There a crash on Wine (Linux and Mac) when running a game

Make sure you're using the last version, we fixed some important bugs with Wine in the version 2021-08-30.

Also, if you previously applied the workaround where you copied some DLL files around, delete them. This workaround is no longer needed, and having old DLL files in the thcrap directory can cause a crash. You should not have any DLL file in the thcrap root folder.

Moreover, if using a customized (non-distro) kernel, it's possible that your maintainer or you may not have compiled it with the CONFIG_CROSS_MEMORY_ATTACH option enabled. This option is (at least for Proton and derivatives) necessary for thcrap to access the game executables' memory for patching.

The patch does not seem to update.

A complete, manual reinstallation of the latest thcrap version usually fixes this.


Something not covered here? Everything just going wrong? We have the solution! (Most of the time.)

Please visit our discord.png Discord or IRC channel #thcrap on Things we would need are OS, game, what you were doing, and the patcher's log file (thcrap_log.txt).
