========================
Example Game:
--------------------------
Napoleon Senki
Notes:
---------------------------
This mapper uses an 8 KiB SRAM to provide 6 KiB of CHR-RAM and 4-screen mirroring!
Registers: (** BUS CONFLICTS **)
---------------------------
$8000-FFFF: [CCCC PPPP]
C = CHR Reg (2k @ $0000)
P = PRG Reg (32k @ $8000)
CHR Setup:
---------------------------
CHR-RAM is fixed at $0800-$1FFF. CHR-ROM is swappable at $0000:
$0000 $0400 $0800 $0C00 $1000 $1400 $1800 $1C00 $2000 $2400 $2800 $2C00
