misc (mostly negative status) changes (#9228)

* cave.cpp : use u58 from parent set for 'donpachikr' - fixes corrupt graphics in ending
* kyugo.cpp : mark PROMs in 99lstwarb as bad, there's no way these PROMs can give the correct colours for the unique 1st stage in this set.
* tsamurai.cpp : mark nunchaku PROMs as bad, there's no way these PROMs can give the colours seen in reference videos, if these *were* on the PCB it must have been a bootleg conversion
* megaplay.cpp: : demote mp_bio to NOT WORKING, it frequently locks up on continue, usually the 2nd or so continue on the 2nd stage, likely another manifestation of the mp_shnb3 timing comms issue.
