Title pretty much explains it all, I am using AddmusicK and I want to use only one song for my bowser fight to hopefully remove load times.
Code
!Bowser = #$0D !Bowser2 = #$1F !Bowser3 = #$20 !BowserDefeated = #$21 !BowserInterlude = #$22 !BowserZoomIn = #$23 !BowserZoomOut = #$24
Replace the values # $ 1F, # $ 20 ... by the number of the music you want.
NOTE: I'm not tested this!
