This Japanese SMS/Sega Mark III game cartridge board contains [[ MapperPinouts#x3155235 | 315-5235 ]] mapper chip and two custom 40-pin 16-bit ROM chips (128Kx16) in "byte mode" to make them 512KB in total, unlike it's US and European counterpart which contains only one 8-bit ROM chip (512Kx8). The ROMs have the first and second halves of the data respectively. Their CE pins are connected to _CE1 and _CE2 on the 315-5235 to enable them, rather than _CE0.
