Any programmers familiar with Reactor?


Recommended Posts

According to DP, the thought is that scoring over 200K triggers the programmer's initials. I posted the link in the HSC thread, but here it is for everyone else:

Congrats! I hope to trigger it today, but I still have some work to do. ;)

	   lda	$A1		;3 game in progress?
   bne	LF14C	  ;2 branch if so
   sta	$F2		;3
   ldy	#$1C	   ;2 set LSB pointer to square
   lda	$9D		;3
   and	#$E0	   ;2 score at least 200,000?
   beq	LF134	  ;2 branch if not
   ldy	#$26	   ;2 set LSB pointer to "CH"

No theory at all. I believe that there is some uncertainty due to that first check. Ram location $A1 contains various flags that are set during a game in progress. If any residual flags were not cleared somehow, the easter egg will not be shown. I suppose that more investigation is required to find out if these circumstances appear in a game. But yeah, the act of passing 200k will cause the next test to fail - displaying the initials.
