A confuse on JCPSP (latest version)

[JaCk IN Core]

My JCPSP has no problem with voice. but only the music OP of the game, when it come to gaming background music is still fine
I usually download new version and delete old version type
I only take out the ISO of my game and place it in umdimages of new version

does this cause the music OP of the game crash ?
