Alrighty, we all have barely more than a day before Nintendo shuts down all legacy WiFi connectivity in favor of their next generation consoles.

A huge chunk of the WFC community have prayed that awesome hackers would create some sort of custom server for very popular games such as Super Smash Bros. Brawl, various Pokemon games, and Mario Kart.

And, guess what? That's sorta the case. I'm just going to cut to the chase.

Do yourself and friends a favor. Find game IDs by the reference or by Google, and get your game FCs. Input, submit, and wait at most 24 hours.

By the time all the pavement hardens, you will be able to connect to a very special DNS (176.9.146.163) and play your games online.

For those of you playing Brawl, please refer to this forum.

Help yourself and friends.

EDIT
Well, that's the end of that.
If you missed it, you still
have the opportunity to
connect, but you will have
to restart your game. So...

EDIT 2
DAMN.
