whatever it turns out to be it won't sell...
us DC owners who are really into it have everything we want/need for dc hundreds of games , like 20 controllers couple keyboards, 5 systems, LOL
the hardcore dc guys are like packrats man, we horde everything since it's no longer in production... we buy things just to have them...seriously
dc on a chip like that will be worthless, we have what we need/want already... plus dc on a chip isn't original so collectors won't care (the main majority of the hardcore dc scene)
the new people will say eww dreamcast, eww sega, ewww graphics, ewww wtf is a dreamcast i'm too young to know, or ewwww is it an overpriced dvd player or a second rate gaming system?
it will fail like every other aftermarket idea like that... plus they still make dc's over there in brazil so if anyone really did want something different like that they'd just import one
