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 100 games. Read »Development of Wiimmfi« for details.

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.
