The last post introduced you to RiiFS, a program allowing you to connect your computer to your wii, eliminating the need to swap your SD card between your Wii and computer every time you want to change patch content. But RiiFS also allows you to play levels and mods online, by connecting to a server hosting playable content.
Simply download the XML for the server you want to connect and put it in your ‘riivolution’ folder on your SD card, replacing your existing XML patch file for NSMBw. For the latest list of servers, go here. At time of writing, two servers were featured: one to play featured NSMBw levels, and another to play the most popular levels.
For more info, go here for the featured levels server, and here for the most popular levels server. for information on the network element of Riivolution, go here.
