currently I'm looking for Games that didn't got a localization.
I just found the Game "Liar Princess and Blind Prince" which is a Korean-only Game.

I've looked into the Gamefiles and I believe I've found the Files that needs to be changed:
File Location: romfs/database/
The Korean Text is readable when you open the files in Notepad++ and Convert it to UTF-8
Editing them in Hexeditor or Notepad++ would break stuff I believe, because the pointers will be wrong.
Would you help me with an Editor for these files (or a Tool that convert this file to editable textfiles and to rebuild them?
The Format seems to be very simple.
I've uploaded the files and attached them to this post
