The Bonus Stage Fail music is almost impossible 
to logging! I have tried three methods:

First, I have tried to strip YM2151, but strip all
the music. Second, the M1 don't support any of
Sega System 24 games (maybe to a disk image?).
And the third, I have using the MAME Debug, but
I don't found the music trigger or a YM2151 mapped
adresss, and with 2x68000? It's much trouble for me!


Bonus Stage Fail music is now logged but incomplete,
because the sound test lacks its music and
unavoidable SFX interrupt channel 7 ingame.
I hex-edited the SFX out, but there're still some
notes supposed to play that don't play.
