This is how the Zeebo port of Super Mario 64 runs right now, still some graphical glitches, but with a much better framerate and targeting 640x480 (the same resolution as the PS2/DC ports, double that of the original from N64, and higher than the resolution of the 3DS/PSP ports).
Super Mario 64 is being ported to Zeebo by Pedro from Zeebo Eterno/Hardwarelandia, same guy from the GBC, SNES, and Genesis emulators.
He’s extremely talented, I'm amazed by how fast this port has progressed.
