For some optional song patches there is included a folder labeled 'soundtrack_b', if you have patched 'Soundtrack B'. Make sure to use them instead or the song pointers and/or instruments will get messed up.

These patches will not change/update the names of the default songs in the in-game Music Player.
You can listen to the included SPC audio files with an SPC player. I recommend the SNES SPC700 Player.
