hm...I got mario running really well, but all other games are running terrible. Lylat Wars is smooth, but slow and the audio is broken. I hope there's going to be some improvements during the next couple of weeks
Here's a video I made playing Mario 64:

EDIT: Apart from the performance issues, n64 looks just great on the nook. Banjo Kazooie and Zelda look amazing
And is it just me, or are all textures shown at full detail? Looks like there's no mipmapping, or full anisotrophic filtering, which could explain the performance issues
