I know a flaw in the DSi firmware updating, since not everyone has access to WiFi(me inclusive, my brother altered the Router login), meaning people could stay with an old one. But knowing the Wii way slightly, we'd have the option to update.
What I don't know is: Do some of the firmware updates let us play the newer games (On the other consoles that is, PS3, 360, Wii)
I'm still surprised it was AceKard who got it.
