Falcom Modding tools??

Sooo...I am still working on the translation of Dragon Slayer: New Heroes Legend of the PC.
What got me hooked to the game despite me playing it on the Turbografix CD was seeing screenshots of the game...somehow in Chinese language.

Since I am trying to translate the game text, why don't I translate the menu image to match the characters' names? They did that here, I thought.
I tried using the Falcom Data Archiver Conversion Tool or "falcnvrt" for short to extract the images but with no avail. Turns out the game "新・英雄伝説" is not in the compatibility list (somehow they listed New Heroes Legend III White Witches, which tricked me).
Is there a way to get in the data files of the game? They are in DAT format and from my research, they are impossible to crack with normal means.
