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 Tenka no Goikenban: Mito Koumon (J). This game uses the Sunsoft-2 chip on the Sunsoft-3 board, and so works differently than Mapper 93

Here is the documentation in disch's original style:

 Registers **BUS CONFLICTS**:
 --------------------------
 
   $8000-FFFF:  [CPPP MCCC]
     C = Select 8k CHR @ $0000
     P = Select 16k PRG @ $8000
     M = Mirroring:
       0 = 1ScA
       1 = 1ScB
 
 
 PRG Setup:
 --------------------------
 
       $8000   $A000   $C000   $E000  
     +---------------+---------------+
     |     $8000     |     { -1}     |
     +---------------+---------------+
