Changes for this version 1.4b:
Removed Patch A & B because it's no longer needed since 
I found a way to do this without a problem now.

Changes for this version 1.4a:
Fixed the script for not showing at the ending credits on the
Bloody Malth picture. I think the code is in the NMI setup.


Changes for this version 1.4:
Thanks to PolishedTurd for the info:
Fixed a bug where Right after the last cutscene, the music for the end credits starts to play, 
and then the screen flashes gray and the music stays frozen on the current sound. It happens right when the image and text for the credits would appear.
It was the bankswitch code.
-----------------------------------------------------------------------------------------
Changed the main mirroring swap to a new default location $FFF6
I managed to fix all of the cutscenes mirroring.
I also managed to fix the messed up graphics for the cutscenes too. I add this
at $101F9 - $81E9 LDA #$01 STA $5101 and mirroring at $10209 - $81F9 to the default
mirroring location JSR $FFF6


Changes for this version 1.3:
Moved strikeable items to appear properly code to a new location at
$1FC00 - $FBF0

Changes for this version 1.2:
Fixed the CHR Right PPU screen and changed the PRG/CHR swapping with MMC5 equivalents to JSR's
to the fixed location.

Changes for this version 1.1:
Added two patches for this mapper hack.
