INES Mapper 153

iNES Mapper 153 represents the board containing the Bandai LZ93D50 and an 8 KiB SRAM.

This mapper was apparently added by Xodnizel for FCEU to describe a mapper 16 with SRAM in place of EEPROM and an extra control bit for banking. Ideally, an emulator could distinguish the SRAM board from the EEPROM board by looking at nonvolatile RAM size in the NES 2.0 header, but some emulator authors have been late to implement NES 2.0.

• Famicom Jump 2 (J)
  • Header and bootgod seem to usually indicate mapper 16.
  • FCEUX and nestopia force the use of mapper 153
