INES Mapper 097
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)
