M&S at the Rio Olympics 3DS sound format?

Hi , i was wondering if someone already ripped the voices from this game.

I mean , most are in the page up already but there are several missing.

I tried looking in the game myself but i cannot find bcwavs whatsoever in any of those files.

So , does anybody know where are the voices located and what format are they?

I know there's a bcsar in this game but it has nothing of that. I just want a couple of sound effects.
