  ========================
 
 
  Example Games:
  --------------------------
  Pocahontas
  Super Donkey Kong
 
 
  Registers:
  ---------------------------
 
  This mapper is an [[MMC3]] with its registers all scrambled to hell.  Rather than a typical register outline,
  this section will "translate" mapper 182 registers to their coresponding "normal" MMC3 counterpart.  For MMC3
  details, see [[INES Mapper 004|mapper 004]].
 
  Range, Mask:  $8000-FFFF, $E001
 
 
    Mapper 182    MMC3
    --------------------
      $8000        -
      $8001      $A000
      $A000      $8000 (addresses further scrambled, see below)
      $A001        -
      $C000      $8001
      $C001      $C000+$C001 *
      $E000      $E000
      $E001      $E001
 
 
  A write to $C001 would be like a write to both $C000 and $C001 on a normal MMC3 (sets reload value, and
  clears the IRQ counter).
 
  The Address/Data port registers are further scrambled:
 
 
    Mapper 182    MMC3
    --------------------
        R:0      R:0
        R:1      R:3
        R:2      R:1
        R:3      R:5
        R:4      R:6
        R:5      R:7
        R:6      R:2
        R:7      R:4
 
  Other than this scrambling mess, the mapper operates exactly like a normal MMC3.
