Its on fuwanovel. Someone made an script when I asked there quite a while ago.
Its a very simple extract and repack python script.
Here is my post on the fix to properly display the dialogue.
You must be registered to see the links
Image translation should work fine and dialogue can be made using this workaround.
But the main problem is that there is no rpg texts.... item names/descriptions etc.... If anyone can find where that stuff is located it would be great.
EDIT:
Oh yeah, remember that on the extract.py you need to change the filename for the one in the game you want to use.
Line 38 if not os.path.exists('FGN_BOOT_T.DAT'):
Line 43 with open('FGN_BOOT_T.DAT', 'r') as f:
in the case of this game it should be DSP_BOOT.DAT
I also like to put an if inside files loop ~Line 49
To only extract the files I want, because it takes too much time and space to unpack all the things.
So for example if you only want the dialogue text you could put there a:
if file != "DS_ADD.DAT":
continue
