How to play Mario Kart Wii online on Wiimmfi with JUST a custom DNS (Wii/WiiU, no Homebrew, no SD)

Celebrating the 7th anniversary of the Nintendo WFC shutdown, we are releasing a brand new Wiimmfi patching method for Mario Kart Wii and a couple other Wii games that works on Wii and WiiU, does not require Homebrew or an SD card, and works just by using a custom DNS.

To use it, just go into the Wii or WiiU network settings and set the DNS to 95.217.77.181.

This method is compatible with Mario Kart Wii and Super Smash Bros Brawl, the two most-used Wii games on Wiimmfi. A list of compatible and incompatible games can be found at https://forum.wii-homebrew.com/index.... but that list is by no means complete. If a game isn't on that list, just try it and see if it works. Also, this method will NOT work on Dolphin, so if you're using the Dolphin Emulator you'll need to use a patched image just like before.

For more information see this Wiimmfi page: https://wiimmfi.de/patcher/dnspatch

Troubleshooting:
- If you receive error 23400, either you didn't enter the DNS correctly or your router or ISP is blocking custom DNS from working correctly. See https://wiimmfi.de/patcher/dnspatch#c... for more information
- If you receive error 20110, it looks like you are trying to use a game that seems to not be supported by this method.
- If you receive error 20100 in a particular game, but you CAN successfully connect using Mario Kart Wii, please let us know what game that is so we can look into it.
- If you receive error 60000 in MKWii, create a new license, connect to Wiimmfi with that, play one race online, then go offline and try the previous license again, and the error should be gone.


Legal notice: Connecting to the DNS server at 95.217.77.181 may execute custom unsigned code from Wiimmfi on your Wii or WiiU console depending on the game.
