NES 2.0 Mapper 386 denotes J.Y. Company's YY860729C circuit board, used for only one known multicart:
- 1996 Super HiK 5-in-1 (JY-090)
It uses the J.Y. Company ASIC, has 1 MiB of PRG-ROM and CHR-ROM each, and is similar to NES 2.0 Mapper 282 but has the Outer Bank register bits in a different order. NES 2.0 Mapper 387 is almost the same but changes the outer PRG bank size from 256 to 128 KiB.
Outer Bank Register ($D003)
Mask: $F003 7654 3210 ---- ---- ..L? PCpc || |||+- CHR A18, ignored if L=1 || ||+-- PRG A18 || |+--- CHR A19 || +---- PRG A19 |+------ Always 1 +------- Select outer CHR-ROM bank size 0: Mask $900x/$A00x to 256 KiB, use c 1: Mask $900x/$A00x to 512 KiB, ignore c
For a description of all other registers, see J.Y. Company ASIC.
