Seems plausable.
there have been reports of the xbox 360 having been 'cracked'.
None have proven to be real yet, but I don't dounbt that this NES thing is possible.
I'm moving this to emulation discussion as... it's emulation discussion.
umm, honestly I personally don't give a crap, but then again I guess it would be cool to the people who do give a crap, but i woudnt choose to do it since they are from 2 completely different companys.
well the xbox coulld run romz and hacks in the hardware, it had more than enough power so it would be link squeesing a pea for the 360 to do it, i wouldnt be suprised
i play my xbox so i can play the good ol' mortal kombat and killer instinct
