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

| ++-+----- 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.
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.
