NOTE: SMRPG does not use an absolute address for storing final damage/health (i.e 7E:????).
      It uses a direct page, $C2, and subtracts/adds the result (after stat modifications) from
      current HP and uses difference/sum to determine outcome (this is all determined before
      the actual attack/spell animation and final damage digit display). Thus, it is impossible
      to directly edit the final damage through a PAR code.
