The Nintendo Wi-Fi Connection
(WFC) service was an online gaming service
that provided free online play in various Nintendo DS and Wii games.
Nintendo discontinued the service on May 20th, 2014,
primarily because the host of the service,
was shutting down its servers.
Nintendo WFC was required for online play,
but the Wiimmfi Project
has replicated much of its functionality
and allows for continued online play in Mario Kart Wii and other games.
Wiimmfi is available for the public since
May 10th, 2014 (10 days before WFC shutdown).
It started with Mario Kart Wii and supports now more than
To use Wiimmfi, the games must be patched to use the new domains and
also to change some other settings.

for more details.

Remember that Wiimmfi is a free service, so please be patient
if I stop the servers temporarily to fix bugs or to update the system.

Competition service server change
The Mario Kart Wii competition service will be moved to
another server, so the competition page will be down sometimes.
This neither has influence on the Wiimmfi server itself nor on
the in-game competition rankings, only the competition web page
will sometimes be unreachable and the competition patcher might
not work correctly.
The next competition will then start after the server change,
on July 20th.

At the moment Wiimmfi supports more than 80 games.
