If you're looking to translate a Kirikiri game, take a look at VNTextPatch.

KirikiriDescrambler

Some Kirikiri games have their plaintext scripts (.ks/.tjs) scrambled or compressed. Such files can be recognized by the following signatures at the start:

FE FE 00 FF FE
FE FE 01 FF FE
FE FE 02 FF FE

KirikiriDescrambler turns these into regular text files which can be placed right back in the game - no rescrambling needed.

KirikiriUnencryptedArchive

A DLL (named "version.dll") that makes games accept unencrypted .xp3 archives. By using this file, it's no longer necessary to identify and replicate the game's encryption when trying to add/replace .xp3 files; just create an unencrypted one with the Xp3Pack tool in this repository, throw the version.dll in the game's folder, and you're done.

The DLL produces debug messages that can be seen with Microsoft's DebugView tool - this can be handy to confirm it's working.

Some special features are available for helping with .xp3 archives that contain encrypted/hashed file names and aren't supported by other tools. Specifically, these features are available if DebugView shows a message such as "Hooking storage media 'arc'" when the game starts up (this doesn't apply to the media "psb").

• If there's a file called extract-unencrypted.txt in the game's folder, the DLL will extract any files that the game accesses into a subfolder called "unencrypted", with their original names. Note that the files are only extracted as the game reads them, so if you want to extract everything, you have to skip though the entire game. If you can extract the archives with another tool, use that instead.
• If a file exists in the "unencrypted" folder, the game will use that one instead of the original in the encrypted .xp3 archives.
• If a file exists in an archive called "unencrypted.xp3", the game will use that one instead of the original in the encrypted .xp3 archives.

Xp3Pack

Creates unencrypted .xp3 archives for use with the KirikiriUnencryptedArchive DLL. Unlike other packing tools, it sets all hashes in the file table to zero; this serves as a marker for the DLL to bypass the game's decryption for those files.

Typical usage is to place Xp3Pack.exe in the game folder, create a "patch" subfolder containing the files you want to include, and run "Xp3Pack patch" from the command line. This will create a patch.xp3 in the game folder. If the game already has its own patch.xp3, name your folder "patch2" and run "Xp3Pack patch2" instead. If the game already has a patch2.xp3, name your folder "patch3", and so on.
