FIXSMASH.ASM

;;===============================================================================
;;
;;   I think this patch is unused because LAST.ASM overwrites
;;   the patch at $4BCF with a jump to $FFB0 not $E1C7.  Does this mean
;;   $E1C7-$E1D3 is not used at all?
;;
;;   The FORCEON patch at $FFB0 is exactly the same...at first it was confusing to
;;   see that but I think there's a reason:
;;
;;   Since $FFB0 is part of the diagnostic ROM and the game can be built without it,
;;   perhaps the devs moved this patch over to prevent operators from running
;;   the game without the diagnostic/watchdog ROM.
;;
;;   To avoid double symbol errors, FORCEON has been renamed to ZFORCEON
