He's looking for a way to get wav files from this, somehow, ideally through an arcade music emulator (M1 or such) with wave writing. And he's tried M1, at least. I suggested he ask here in case someone knows about these particular games.
Crystal System is a full custom system-on-a-chip (even the CPU's custom). Not impossible to make play sequences on command but may as well be.
Princess Clara Daisakusen uses one of the "bad" driver versions and can't easily be ripped to SSF. But you can run MAME with -wavwrite and press F2 to enter the sound test and play all the songs in their entirety there.
