| INES Mapper 016 submapper table | ||
|---|---|---|
| Submapper # | Meaning | Note |
| 0 | Unspecified | Emulate both FCG-1/2 and LZ93D50 chips in their respective CPU address ranges. |
| 1 | LZ93D50 with 128 byte serial EEPROM (24C01) | Deprecated, use INES Mapper 159 instead. |
| 2 | Datach Joint ROM System | Deprecated, use INES Mapper 157 instead. |
| 3 | 8 KiB of WRAM instead of serial EEPROM | Deprecated, use INES Mapper 153 instead. |
| 4 | FCG-1/2 | Responds only in the CPU $6000-$7FFF address range; IRQ counter is not latched. |
| 5 | LZ93D50 with no or 256-byte serial EEPROM (24C02) | Responds only in the CPU $8000-$FFFF address range; IRQ counter is latched. |
If there are 256 bytes of serial EEPROM, they will be denoted as PRG-NVRAM in the NES 2.0 header (byte value $20). See: INES Mapper 016
