actually, that's debatable. see the reason most emulation isn't perfect, is because there's no precise understanding of the hardware, it's all reverse engineered and methods are developed to get around certain things... hence needing alot of processing power. however, if sega does give nintendo the schemantics and all the details, and works with nintendo, then dc emulation MIGHT (stress the word MIGHT) be possible. Possible, yes. At a decent speed? Probably not. More likely than not, dreamcast games would have to be ported, or half-ported like the xbox1 games on the xbox360. PSX is magnitudes more simple than the N64.
