MUSHIKING TKOB 2K3 2ND KOR, (C) SEGA CORPORATION, 2003, NAOMI M1 cart.

The cart is populated with an EPROM and 6 MASK ROMs.

This is a standard M1 cart. On M1 carts data is stored as 32-bit words,
however each of the MASK ROMs contain only 16 bits of the 32 bit word. 
In order for the dump to truthfully represent what is present on the 
PCB I have split the data across each pair of chips. This is the same
which has been done for gram2000 in the NAOMI driver. 

The split algorithm is as follows:

copy /b a1000000.bin+a1800000.bin merge.bin

do
get 1 byte from merge.bin and write it to nn.ic17s
get 1 byte from merge.bin and write it to nn.ic17s
get 1 byte from merge.bin and write it to nn.ic18 
get 1 byte from merge.bin and write it to nn.ic18 
while !eof in merge.bin

This dump has been verified against the cart ROM test. Do not
be alarmed even if you do not see the test of IC11. It has 
been disabled in the header.

Note:
This game requires a Korean BIOS
