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 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}     |
     +---------------+---------------+
