Convert the music to brsar extension and replace it like the tut says, dunno if its gonna work.
I think that's not possible to edit the SFX(not that i know how) but u can listen to the songs from the BRSAR files
Brawl Box can do it as well, but you must specify loop points in the song. Don't use the BRSTM-GUI or whatever it's called, it doesn't loop songs properly.Try this
