iNES Mapper 097 represents the single game that uses Irem's TAM-S1 IC, Kaiketsu Yanchamaru.

 Registers:
 --------------------------
 This mapper does not have bus conflicts.
 
   $8000-BFFF:  [M..P PPPP]
     P = PRG Reg  (16k @ $C000)
     M = Mirroring:
        %0 = Horz (PPU A11)
        %1 = Vert (PPU A10)
 
 
 PRG Setup:
 --------------------------
 
       $8000   $A000   $C000   $E000  
     +---------------+---------------+
     |     { -1}     |     $8000     |
     +---------------+---------------+

The underlying hardware is a little more capable, but is wired in a way such that that is inaccessible.

Mapper 180 is basically this mapper without mirroring control. (But the fixed bank is 0, not last)
