This is part of a family of Sunsoft mappers used largely by Japanese games: (iNES Mapper 089, iNES Mapper 093, iNES Mapper 184)
This mapper is used by Shanghai (J) which uses the Sunsoft-2 mapper chip, as well as Fantasy Zone (J) which uses the Sunsoft-1 mapper chip but is wired differently than other boards that use the Sunsoft-1 chip. (See Mapper 184 for more information). Also see Mapper 089 for another Sunsoft-2 game which works a little differently.
Fantasy Zone (J) is noteworthy for making mapper register writes in pairs which are designed to program the iNES Mapper 093 board configuration described here, as well as a modified Mapper 184 with some signals routed differently.
Here is the documentation in disch's original style:
Registers:
--------------------------
I don't know if this mapper suffers from bus conflicts or not. Use caution!
$8000-FFFF: [PPPP ...M]
P = PRG Reg (16k @ $8000)
M = Mirroring:
0 = Vert
1 = Horz
PRG Setup:
--------------------------
$8000 $A000 $C000 $E000
+---------------+---------------+
| $8000 | { -1} |
+---------------+---------------+
