NES 2.0 Mapper 385 denotes the NTDEC 2779 circuit board, used for a simple 5-in-1 multicart with 8 KiB of unbanked CHR-RAM containing NROM-128 games. It is similar to INES Mapper 202 except that there is no NROM-128/256 switch, and that it uses CHR-RAM rather than CHR-ROM.

Address Latch ($8000-$FFFF, write)

Mask: $8000
