You find where you have installed game.
(on Steam is in <Steam path>\steamapps\common\Jigoku Kisetsukan)

Here are 3 folders which contains text data. These ones:

• en - english language
  
• it - italian language
  
• jp - japan language

You can't add new language only rewrite existing.

All files can edit in notepad or similar program. In game you choose language that you rewrite.

Note: I recommend for editing Notepad++

Most texts are in "strings.ini", it contains all game message, menu and description of all characters. Story dialogues are in folders divided by levels, where file name is name of character.

Note: You can edit when game is running, just save changes and refresh page in game.

All the translated text is in quotation mark ( " ).

Some rules and tips:

• # - this character works as new line,
  
• characters like these á, í, é are supported, (except game section)
  
• characters like these č, š, ž are not supported,
  
• in "[game]" section supported only default characters set (without special characters like á,č,ô and other)
  
• in character description have one page 10 lines (i think that pages are not limited),
  
• you must check character description, because every character have other size of image and sometimes this image can hide text

Note: In my language are supported these two special characters, "ä" and "ô"

Dialogues have similar rules as "string.ini". Here showing text is not in quotation mark ( " ), but after this text "dialog::".

Note: Here is better use another program as notepad, because in notepad is all text in one line.

Some rules and tips:

• "#" is new line, too,
  
• dialogue box have only 3 lines,
  
• one line have length about 50 characters,
  
• when text is longer, it will be out from box
