Seems RetroArch Vita will have a Nintendo 64 (n64) emulator soon and reports suggest it's running Super Mario 64 at full speed with sound already surpassing the PSP emulator in its first incarnation. There are even talks of the Dolphin EMU core right around the corner. Move over PS3 seems the PSTV is kicking your butt. N64 emulation has long been a dream for the PS3 but with the Cell architecture porting is not an easy task without significant re-writes to an emulation geared specially for the system (ps3). However the Vita & PlayStation TV things are stacking up differently, while still a challenge it's appearing its a much more reasonable task to achieve as we witness this unfolding.
