Known Errors:
Bugfix provided by Bandit:
  • Killing the Night Slasher when you have the invincibility power-up causes the game to never end. In this case, you are left to endlessly stroll around the level without any enemies. Fixed using the following patch:
          org $9490       ; 38032
    jp $aef0 ; 195 240 174

    org $aef0 ; 44784
    cp 7 ; 254 7
    jp z,$9566 ; 202 102 149
    jp $956a ; 195 106 149

Bugfix provided by zxbruno, jp, and Einar Saukas:
  • The original release synchronized with video display by reading IN $FF port, however this routine was incompatible with +2A/+3 due to hardware differences, causing the game to freeze in an infinite loop:
    95fe: ld bc,$3f28
    9601: ld a,c
    9602: in a,($ff) ; register 'A' always set to $FF in +2A/+3
    9604: cp b
    9605: jr nc,$9601 ; repeat forever!
    9607: ret
    The Hit Squad re-release solved this problem by replacing this routine with a fixed loop:
    95fe: ld bc,$0300
    9601: dec bc
    9602: ld a,b
    9603: or c
    9604: nop
    9605: jr nz,$9601
    9607: ret
