Here are the services that RiiConnect24 supports.
RiiConnect24 is a great addition to your Wii, allowing you to use discontinued Channels that were part of WiiConnect24 again. It makes your Wii as lively and lets you participate in a community, as it once was. Whether this will be your first time using these Channels or want some nostalgia, you will enjoy having RiiConnect24 on your Wii.
If you want to play games online that had their online functionality removed with the discontinuation of Nintendo Wi-Fi Connection, please check out Wiimmfi.
