INES Mapper 094 is used to represent the board HVC-UN1ROM. Senjou no Ookami (Japanese version of Commando) is the only game known to utilize this mapper. It is very similar to UxROM, but the register is shifted by two bits.
Overview
- PRG ROM size: 128 KB
- PRG ROM bank size: 16 KB
- PRG RAM: None
- CHR capacity: 8 KB RAM
- CHR bank size: Not bankswitched
- Nametable mirroring: Solder pads select vertical or horizontal mirroring
- Subject to bus conflicts: Likely
Banks
- CPU $8000-$BFFF: 16 KB switchable PRG ROM bank
- CPU $C000-$FFFF: 16 KB PRG ROM bank, fixed to the last bank
Registers
Bank select ($8000-$FFFF)
7 bit 0 ---- ---- xxxP PPxx | || +-++--- Select 16 KB PRG ROM bank for CPU $8000-$BFFF
Here are Disch's original notes:

Registers:
--------------------------
I don't know if this mapper suffers from bus conflicts or not. Use caution!
$8000-FFFF: [...P PP..] PRG Reg (16k @ $8000)
