The same problem also affects sws95,96,97 (and probably others), I believe the shadow palette offset needs to be set to 0x800 for the nb1/2 hardware.
In video/namco_c355spr.cpp:
this, for instance, could be made configurable.
const int shadow_offset = (palette.shadows_enabled()) ? palette.entries() : 0;
The extra shadow palette - which is a brightness-reduced copy of the palette at the end of the palette is not needed for this hw.

best regards,
