INES Mapper 242 is a smaller version (512 KiB only) of the multicart variant of INES Mapper 227 that is also used for a few 512 KiB single-game cartridges. The only functional difference is that reading the solder pad is accomplished by setting bit 8 (value $0100) instead of mapper 227's bit 10 (value $0400).
