File this one under "What the hell?" Some astute gamer has discovered a hidden feature inside the Nintendo Wi-Fi Connection setup menu, and one that certainly leans itself toward DS-to-Wii connection theory. The video gives an extremely detailed explanation, so check it out....now. Go ahead.
Done? All right. The system asks for the player to press a "Simple Start Wi-Fi Button", something that clearly doesn't exist on any existing Nintendo hardware. So, is this how the Wii and the DS will sync up? Before you run off wildly screaming the news throughout your house, we offer these two bits of counter-evidence. First, regading the Wii, we've seen essentially every button and switch on the damn thing, even inside the "mysterious" front flap; no "Simple Start" or even remotely related button has been seen or reported. Second, accessing this mode by hitting the absolute upper-left pixel on the touch screen is ridiculous; in certain cases the stylus can't even reach the pixel, and a toothpick or other thin, prodding device must be used.
We've seen no reason why "DS Download Play" would fail to properly pick up and sync with a Nintendo Wii console, so we'll chalk this up as a feature that will fade, like the legendary city of Atlantis, into one of the unexplained mysteries of the past.
[Update 1: The internet, it seems, will brook no mysteries. Save Atlantis. Click here for an extremely detailed explanation of this feature, and as speculated, it has nothing to do with Wii connectivity.]
