Also, seems like the server can still send downloadable content, so games like WarioWare D.I.Y and Picross can still be enjoyed past game. Also with the Friend Storage thing, I guess.
So, it's a good alternative, but for some games, it seems to require some modifications I won't talk about.
Actually, the downloadable content comes from the new server, not the official one.
How? I don't know actually, they must leaked the needed data.

I never saw of this !!! I'm not sure if it will still work though :/ This really does sound like a good thing and maybe later I'll try it out , though I got bored of Ds games . . . I still have some doubts about this though , maybe the people using this to play online might lack , but still a good thing
