BFSAR (File Format)

A BFSAR file is an archive containing sound effects. In NSMBU, it also contains all music streams, but I don't think this is the case for MK8.
Format
I found this information by reverse engineering NSMBU and analyzing the files. I think the same applies to MK8, but since I don't have MK8's files, I can't assure this.
