Adding savestates would help admins checking the issue faster.
I've played the thing and confirm it ocurrs.

The bootleg (nobb) doesn't have the issue which leads me to believe it may be protection related or a fault of the i8751.
Added Save State N (from 0.203) to bring you just before the start of the next level.
Confirmed the first version the parent became playable this issue exists. (0.131u2)

the code gets patched by MAME in the bootleg because we couldn't figure it out,
/* Patch to get sound in later levels(the program enters into a tight loop)*/
address_space &iospace = m_maincpu->space(AS_IO);
uint8_t *ROM2 = memregion("soundcpu")->base();
ROM2[0x02f9] = 0x28;//'jr z' instead of 'jr'
there's no patching on the original set, and the sound rom is the same, so....
maybe there's a way for the main CPU to reset the sound CPU, or maybe the sound CPU has it's own watchdog, although it isn't documented if there is
