- 1997 Super 13-in-1 (JY-110)
Its UNIF board name is BMC-13in1JY110, although FCEUX' support is non-working. It uses the J.Y. Company ASIC.
The same bits in register $D003 select both PRG and CHR outer banks. It is almost identical to NES 2.0 Mapper 281, except that the outer bank size is 128 KiB rather than 256 KiB.
