I bet that there are only 4 or five games which the general gaming community would care about .
Zelda Ocarina of Time, Zelda Majora's Mask, Super Smash Bros. Paper Mario, Paper mario, and maybe Some other stuff such as banjo kazooie.
Edit: also, sadly, I just realized this, The DS doesn't even have enough buttons to emulate the 64. the only way it would be possible is if you had some weird control scheme in which you either use the touch screen, a combo of buttons, or a pressing a button to swich the face buttons with the C buttons like select, So not only is it impossible for the hardware, it's also impossble with the controls. However the pandora probably will be able to emulate at least some N64 games.
