Wiimmfi Main Page


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, GameSpy, 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 80 games.

To use Wiimmfi, the games must be patched to use the new domains and also to change some other settings. See »Wiimmfi Patcher« for more details.


This part is used for announcements. 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.


January 2017

PHP code clean
At the 7th of January I started a PHP code clean.

In 2014 I began to implement different servers (e.g. NAS login and GPCM) and also the Wiimmfi portal using the programming language PHP. I also developed a Wiimmfi PHP library for common threads. In the beginning, it was a very hasty implementation.

And now, 3 years later, I started to clean and to reorganize the code and to move code to the library. I'll be very careful, but I can't exclude that I'll fail.

False rumours about discontinuation
Some people seem to have received a bogus RiiConnect24 announcement message claiming that Wiimmfi would be discontinued in January 2017. That is not the case. Some guy thought it would be funny to edit a message created by Mario Kart to make it look like an announcement letter and has sent that to a few people.

Update of host server
On Friday, October 21th, 2016, the Linux system of the host will be updated. Therefore, Wiimmfi has to go offline for about 1 hour. The exact time can not be predicted.

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.
