| UNIF MAPR '''FARID_SLROM_8-IN-1''' (note underscores) describes a multicart designed by Farid in 2013. It contains eight 128+128 KiB SLROM games.

| | |
| It replaces the [[MMC1]]'s normal PRG RAM with a single register:
| |
| | |
| $6000-$7FFF: [.BBB K...]
| |
| ||| |
| |
| ||| +---- 1: disallow any subsequent writes
| |
| +++------ Select outer bank for both PRG and CHR
| |
| (i.e. connected to PRG and CHR A17, A18, and A19)
| |
| On both warm and cold boot, this register is cleared.
| |
| | |
| Note that the [[MMC1#PRG bank .28internal.2C .24E000-.24FFFF.29|MMC1's PRG RAM protection register]] may need to be cleared in order to write here. Also note that unlike the rest of the MMC1, all bits are written at the same time.
