iNES Mapper 032 represents games using Irem's G-101 mapper IC. It came in a 52-pin DIP package.

Example Games:
--------------------------
Image Fight
Major League
Kaiketsu Yanchamaru 2
Registers:
--------------------------
Range,Mask: $8000-BFFF, $F007
$8000-$8007: [...P PPPP] PRG Reg 0
$9000-$9007: [.... ..PM] ** see footnote
P = PRG Mode
M = Mirroring (0=Vert, 1=Horz)
$A000-$A007: [...P PPPP] PRG Reg 1
$B000-$B007: [CCCC CCCC] CHR Regs
PRG Setup:
---------------------------
$8000 $A000 $C000 $E000
+-------+-------+-------+-------+
PRG Mode 0: | $8000 | $A000 | { -2} | { -1} |
+-------+-------+-------+-------+
PRG Mode 1: | { -2} | $A000 | $8000 | { -1} |
+-------+-------+-------+-------+
CHR Setup:
---------------------------
$0000 $0400 $0800 $0C00 $1000 $1400 $1800 $1C00
+-------+-------+-------+-------+-------+-------+-------+-------+
| $B000 | $B001 | $B002 | $B003 | $B004 | $B005 | $B006 | $B007 |
+-------+-------+-------+-------+-------+-------+-------+-------+
Footnote:
--------------------------
Major League wants hardwired 1-screen mirroring. (CIRAM A10 is tied to +5V
on this game). Additionally, the register at $9000 is entirely disabled:
the game can only request "PRG mode 0".
A NES 2.0 submapper has been assigned for this difference.
Otherwise you'll have to use a hash check.
Naruko says that only the game "愛先生の OSHIETE 私の星" uses PRG mode 1, which is why it was documented incorrectly for so long.
