V9990 on a 3DO ? I must confess that I don't belive on that ...
Because 3DO
sems to be a "framebuffer" machine. (A machine wich has some area of
it's mainram
with direct access to the video ram , like the PC) Also it's video
engine is 24-bit
(16milion collors).
The machine wich probably may contain a V9990 in my opinion is the
NeoGeo, wich was developed
in 1990/91 and has A LOT of Yamaha technology on it ...
Of course if the Neo Geo has a V9990 it is HEAVILY modified , because
that machine has only few
96kb of videoram ....
It uses the Video-ROM technology , very popular in arcade machines ,
because a arcade board will
aways run the same software it doesn't need to have much videoram (All
it needs is a name table and
a color pallete table)
Also the Neo-Geo has 2kb as work ram for the Z80(3.57mhz) and 64kb for
the 68000 (12mhz).
That's all I know ... If someday I get programming info on the 3DO
system or the Neo Geo I may confirm
that ! =)
Cya MSXers ...
