This was already done by SEGA ... It's name : "Mega 32X"
It's an multi processor (SMP) upgrade for SEGA Mega Drive ... I think
that most people here even heard about it .
It contains 2 Hitachi SuperH-2 processors , an new VDP , superimposing
hardware
and more work RAM for the SEGA Megadrive. It was a pretty complex
machine , the
developers ran away when they saw it ... Most games for it are from
SEGA.
It does use the V9938-like VDP of the Megadrive to generate simpler
backgrounds
while the main VDP (inside the 32X) does the hard work (32k colors).
This thing , I would not doubt if someone says it uses a V9990 or an
custom version of it as VDP ...
Cya MSXers ...
