So I’ve got something… I’ve got a few .idx files, .sub files, and one .srt file. Here’s the Drive link: https://drive.google.com/open?id=0B6s_4U0K-xHScUVFalBrUjBNbUE
If for some reason they happen to be better than Althor’s (though I doubt it) I will do ESB and ROTJ.
Can you try PgcDemux? subtitle files are just 1 file for each language.
