Art Style light trax: .brwar files

Hey,

I'm attempting to rip the sound files from Art Style: light trax for the Wii.

In the file containing the sounds are three folders: BRBNK, BRSEQ, BRWAR.

BRSEQ are sequence files. They are 'hooked' to BRBNK files.
BRBNK are bank files. They assign sounds from BRWAR files values to be used in BRSEQ files.

However, I haven't found any information about .BRWAR files, let alone a method to extract them.

Is there a way to extract from these .BRWAR files?

Thanks in advance

(there's a certain user on this site who asked about games from this series before. I've never ripped from a Wii game before)
