Da Capo: Girls Syphony help

First of all I found an Extractor and can extract data. I see there are .BIN files. I assume these are what I need to find the script? Or are the .op2 files what I need. (They they are named "blindleft" "curtainright" so I assume they are images).

That being said, after the script is translated, does anyone know the way to get the new script back into the game.

I did find a DC translation for a different game...so I feel it can be done :/

Any help is appreciated.
