The first official shots of Mario 64x6 on Nintendo DS are here. They reveal the Daisy's castle level from Mario 64 in full hand-held multi-player dual-screened effect.
The early E3 demo is based around a frenzied star grab, with up to four wireless competitors battling it out via the main, N64-aping camera screen and a secondary map display. If you do manage to grab a star, watch yourself as your rivals attempt to punch it out of your hands. The bounders.
