Crystal Flash Corruption

Explanation by P.JBoy

;;; $A35D: Pre-instruction - crystal flash - stage 2 - after-glow ;;;
{
; The same as power bomb explosion stage 5 ($8B98) except for using colour components as a wake criterion ($A36A..76) instead of [HDMA object $1938]

those colour components never become zero in those rooms
but they actually do become 0 when you lay the next power bomb
which causes the "wake up" action on the HDMA object to be executed
which causes the bug
yeah I think the crystal flash object stays alive
you lay the power bomb
causes the colours to become 0
that gets the crystal flash to clean itself up
and I think that inadventantly breaks power bombs

;;; $A317: Crystal flash - clean up ;;;
