INES Mapper 004

iNES Mapper 004 is a wide abstraction that can represent boards using the Nintendo MMC3, Nintendo MMC6, Tengen MIMIC-1, or Namco 109 chip, or clones of any of the above. Most games utilizing TxROM, DxROM, and HKROM boards use this designation.

A few specific TxROM boards handle the PPU bus differently and thus have separate mapper numbers:

• iNES Mapper 118 covers TKSROM and TLSROM, which use CHR bank bits to control VRAM mirroring
• iNES Mapper 119 covers TQROM, which has both CHR RAM and CHR ROM
