    be sure to make note of the mask -- $4200 does not map to the register, but $4300 does.
 
 
    $4100:  [MCPP PCCC]
      C = CHR Reg (8k @ $0000)
      P = PRG Reg (32k @ $8000)
      M = Mirroring:
          0 = Horz
          1 = Vert
 
  Note the high bit of the CHR Reg.
Note that FCEUX does not honor the mirror bit.


Any games smaller-or-equal to 64/64 are probably actually [[iNES Mapper 079|mapper 79]]. Disch generalized the two mappers to only differ on whether they could control mirroring.

iNES Mapper 113 denotes the HES NTD-8 circuit board, used to create multicarts made for a bunch of NINA-03/06 games.

Example Games:

  • HES 6-in-1
  • Mind Blower Pak
  • Total Funpak

Banks

  • CPU $8000-$FFFF: 32 KB switchable PRG ROM bank (max 256 KB)
  • PPU $0000-$1FFF: 8 KB switchable CHR ROM bank (max 128 KB)

Registers

Control Register

This register is located at addresses: 

F        bit      0
---- ---- ---- ----
010x xxx1 xxxx xxxx

That is, $4100-$41FF, $4300-$43FF, $45xx, $47xx, ..., $5Dxx, and $5Fxx. 

7  bit  0
---- ----
MCPP PCCC
|||| ||||
|+||-|+++-- Select 8 KB CHR ROM bank for PPU $0000-$1FFF
| ++-+----- Select 32 KB PRG ROM bank for CPU $8000-$FFFF
+---------- Mirroring control (0 = Horizontal, 1 = Vertical)

Note the high bit of the CHR select is shifted away from the others.

Variants

This mapper extends the NINA-03/06 with an extra 4 bits of control register. The low 4 bits written behave the same, but the high 4 bits add mirroring control, 1 extra bit of CHR select, and 2 extra bits of PRG select.
