iNES Mapper 157 represents the Datach Joint ROM System, which adds a barcode scanner and unbanked CHR-RAM to a Bandai FCG board.

This mapper implies the presence of a X24C02 I²C EEPROM that is shared across all games that ever use this mapper. Fortunately, only one game is documented to use it.

At least one game additionally has a X24C01 almost-I²C EEPROM.
