Star Horse 2002 (main screens) (840-0102B), SEGA ENTERPRISES, NAOMI M2/M3 cart. 

Cart is populated with an EPROM and 6 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.

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 12 MASK ROMs but physically there are only 6.
