Support for X360 S;G?

[dzastsed]

is there any chance you could add support for xbox 360 version of steins;gate script files? It seems that the decompression partially does work already with some scripts:

however, resulting text files are just gibberish for the most part (it seems that line ends do get properly decoded though?):

some script files also throw out this error:

and results in gibberish as well (apart from different text colors and line ends):

attaching a couple of sample script files too for reference:
script.zip

update: just noticed that I used older build which did not have s;g support yet, so tried extracting with sghd argument, but still no luck it seems

charset changed a bit but still results in gibberish
