Star Horse 2002 (live) (840-0104B), SEGA ENTERPRISES, NAOMI M2/M3 cart. 

Cart is populated with an EPROM and 9 MASK ROMs.

The protection chip is not mounted.

There is a 4MB gap in the memory range from the EPROM to the first,
MASK ROM. This dump is not included.

The dump has been validated against the ROM TEST checksums.

The ROM TEST shows 21 MASK ROMS but this is because SEGA
forgot to update the ROM descriptor table. There are only 
9 physical chips mounted and that means only IC1 - IC18 
are valid.

SEGA did not want to release an updated BIOS so they just modified 
the EPROM headers storing two 8MB ROMs inside a physical 16MB. 
Therefore the ROM test shows 18 MASK ROMs but physically there are only 9.
