[WiiConnect24](https://wikipedia.org/wiki/WiiConnect24) was a service that allowed users with Internet connected Wiis to view the weather and news, send messages to friends, participate in Mii contests, and more. WiiConnect24 was discontinued on June 27th, 2013.
[RiiConnect24](https://rc24.xyz) is a revival service for WiiConnect24 that started in 2015, which allows you to regain its functionality on your console.
There is a patcher that ships both of these services together as one - meaning you get all of the international and Japanese-only channels in one package.
The guide on how to install these services can be found [on WiiLink's website.](https://www.wiilink24.com/guide/)
This guide takes the process of regaining online functionality to your Wii a step further - by allowing the Nintendo Wi-Fi Connection services to function yet again on certain games like Mario Kart Wii. While there are different private servers and services that allow this, the one covered here will be Wiimmfi.
