My nooby Sonic ASM code (causes freezing)

SpecialStageHPZ_CheckActivation:
	move.w	($FFFFFAEC).w,d1	;move subtype to d1
	cmp.w	#0,d1		;check if d1=0
	bne.s	SpecialStageHPZ_CheckActivation1	;if subtype is different, branch to next check
	move.w	#1,($FFFFFAF2).w	;write to emerald specific ram to delete
	bra.s	HPZemeralddeleteend
