  Example Games:
  --------------------------
  Battletoads
  Time Lord
  Marble Madness
 
 
  Notes:
  ---------------------------
  AMROM and AOROM have bus conflicts, ANROM does not
  AMROM and ANROM are capped at 128k PRG
  AOROM is capped at 256k PRG
 
  There is no CHR swapping.  Every mapper 007 game I've ever seen has CHR-RAM.

    $8000-FFFF:  [...M .PPP]
      M = Mirroring:
          0 = 1ScA
          1 = 1ScB
 
      P = PRG Reg  (only 2 bits wide on AMROM/ANROM)
