Wiiチャンネル
"Mario Kart Wii" featured the "Mario Kart Channel", which was available as an optionally selectable channel on the Wii Menu, that presented current regional or worldwide rankings for Time Trials, and the option of sending or receiving ghost data via WiiConnect24 (it is no longer supported and does not function as of June 28, 2013). Mario Kart Channel also offered worldwide tournaments from Nintendo, which were modified courses that sometimes had special objectives. There were two tournaments hosted each month. Despite the Wi-Fi connections discontinuation, fans have created numerous private servers to continue playing online, the most notable being "Wiimmfi" which was launched on May 10, 2014, ten days before the shutdown of the official servers.
