Put the python script in the directory where Game.inf is located and run exARD.py Game.Inf to get Game.Info.
Open it, look for gcode.
reotyan100 is XOR key (ignore the last character)
Then run exARD.py ARDScript.ARD -k reotyan100 to extract ARDScript folder containing the script files.
After translated, rename the folder from ARDScript to Script, then use SNFCompiler to create a new ARDScript.ARD and Game.inf by selecting the Game.Info file.
Some information about the engine:
-The game will read from directory with the same name if you delete the .pak archive (I deleted Story.pak)
-The byte before the string (1F in this case) determines its length.
You can just update it after modifying the string.
-P/s: 0A is line-breaker.
