No.08978 Haze Senior Tester Sep 27, 2012, 18:29	if the cheerleaders are part of the tilemap it's unlikely to be a sprite priority issue. more likely a mirror not being handled correctly, a real game bug, or something with the protection?

It uses colour $0E, which happens to be all black (palette $70-$77 i think). edit so, next likely cause is PROM contents. Did MAME lazily borrow exctscc2 prom dumps from exctsccr assuming it was the same?
