It's an easy cpu to interface and use.  One of it's features is 
that at reset the bus can be configured for 8 or 16 bit wide path,
for standard or varible microcycle and static memory or 
Dram(with refresh).

I'd suspect the Dram support would be valuable in a game at a time 
when large rams were dynamic.
