cant some1 get it out of the ds or out of the wii...? maybe via usb acces ??? (i dont know much about this)
i do have a wii but its pal and it doesnt have the demo... not changing my firmware for a demo :-/
I'm sure it's possible to dump the demo, but I haven't heard about anybody doing it. Either monitoring the network to find where it's being served from or doing a raw packet capture and sticking it back together (although this blows) would work.
