Touch De Uno! 2, SEGA 2000

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 mpr-23063.ic17s
get 1 byte from merge.bin and write it to mpr-23063.ic17s
get 1 byte from merge.bin and write it to mpr-23064.ic18 
get 1 byte from merge.bin and write it to mpr-23064.ic18 
while !eof in merge.bin

This dump has been verified against the cart ROM test.

This game requires a touch screen.
