Language Options
I included two simple scripts that you can apply to these files to do the following (Windows only):

1. Change [Default Tracks]: Switches default tracks to *A:Japanese S:Dialog*
2. Make [Single Audio]: Throws out *English audio* and *Signs&Songs subtitles* tracks
	
To apply these put all the video files into the *Language Options* folder and run the .bat file. <1> Changes existing files, <2> creates new ones in the *output* folder.
