Battle themes (BATTLE.STR), ending music (END.STR), movies' audio (FF4.MV, FF4.MV1)
Notes:
Music can be looped! I had to find the loop points manually by myself, so perhaps it's not 100% accurate. Loop support has been removed in version -2.00, due to some changes in the source code. If you really want this feature, try the previous version (or wait until I put it back... but you may wait for a long time)
