========================

Example Game:
--------------------------
Napoleon Senki


Notes:
---------------------------
This mapper uses an 8 KiB SRAM to provide both 6 KiB of CHR-RAM and
four-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
+-----------+-----------+-----------+-----------+-----------+-------------+
| $8000,ROM |  {1},RAM  |  {2},RAM  |  {3},RAM  |  {0},RAM  |Internal VRAM|
+-----------+-----------+-----------+-----------+-----------+-------------+

When making an emulator, you do not need to care about the specific order of
the CHR-RAM banks: just provide 10KiB from $0800-$2FFF.
