iNES Mapper 148 denotes the Sachen SA-008-A and Tengen 800008 circuit boards, which switch up to 64 KiB of PRG-ROM in 32 KiB amounts and up to 64 KiB of CHR-ROM in 8 KiB amounts using a data latch. The bit assignment of the data latch is the same as INES Mapper 079's, but unlike mapper 79, the latch register is in the CPU $8000-$FFFF range instead of $4100-$5FFF, introducing bus conflicts.
