Yeah, you read that right. Finally, after almost a year of work, we are releasing a new Wiimmfi patching method that works JUST by setting a custom DNS. Wii games like Mario Kart Wii and Super Smash Bros Brawl (and some others, but not all of them) can now be played on Wiimmfi JUST by entering a custom DNS server in the network settings. No patcher or Homebrew or SD card required. This applies to both Wii and WiiU, as the very first method to play Wiimmfi on a WiiU without Homebrew.

We've started working on this new patching method in June 2020, and now (after a year of development), down to the minute exactly 7 years after the Nintendo WFC was shut down, we can finally release this feature for the public.



TL;DR: Set DNS to 95.217.77.181 -> done

The setup process is incredibly easy. All you need to do is open your Wii or WiiU network settings, and change the DNS server to 95.217.77.181 (one digit difference from the "normal" DNS), and then ... you are done. It's that easy.

Just start your game through the disc channel and go online. If you're playing Mario Kart Wii the game will display a short introduction message about Wiimmfi the first time you connect (which you need to confirm), and for future connections you won't see anything unusual other than a short loading screen that can sometimes appear after connecting to Wiimmfi. Games other than Mario Kart Wii won't display anything special at all.

Note: This method doesn't work on Dolphin. For Dolphin you still need a NAND backup and a patched image.
Legal notice: Using this DNS server may cause unsigned code to be executed on your Wii or WiiU console.

If you want to see this setup process and/or the patcher in action you can watch this video:




This new patcher does have a slight disadvantage, it doesn't work with all Wii games. However, it does work with Mario Kart Wii and Super Smash Bros Brawl, which are the two most-used Wii games on Wiimmfi.

Here you can find a list of other compatible or incompatible games (thanks to everyone who helped us collect that information):



For any game that's not on any of these lists that means we have no idea if they'll work. Try it and see what happens.
For games that this patcher does not work with, you can still continue using the str2hax EULA exploit on the Wii - the new DNS also supports that one.

• shutterbug2000 who found a flaw in Nintendo's SSL library on the Wii in some IOSes that allows us to get unpatched games online despite not having an SSL certificate signed by Nintendo.
  
• MrBean35000vr who found three different bugs in Mario Kart Wii, which can be combined together to seamlessly send and load the additional Mario Kart Wii game patches into the game.
  
• MrBean35000vr and Leseratte who implemented all the code to actually use these game bugs to load the additional Wiimmfi patches.
  
• Wiimm who implemented lots and lots of additional code into Wiimmfi in order to make it automatically send the patch parts to the game with the proper timings to make everything work.
  

• You cannot use this patching method if you are using Dolphin, or if you boot your game(s) through an USB Loader. In these cases, please continue using a patched image.
  
• If you receive error 23400, your console isn't trying to connect to Wiimmfi but to the defunct Nintendo servers. Check and make sure you entered the DNS IP correctly. If it's still not working, your router or ISP might be blocking custom DNS. Leseratte has created a small tool that you can run on your computer to act as a DNS server for your console that can help with such blocking. Click here for more information.
  
• If you receive error 20110 (the "WFC has been shut down") error, this means that the game you tried is most likely incompatible. Try a known-working game like Mario Kart Wii to make sure.
  
• MKWii only: If you can connect to Wiimmfi but can't find any players, turn your console off and try again. If it still doesn't work please let us know so we can fix that.
  
• MKWii only: If you receive error code 60000 when connecting to Wiimmfi on one of your MKWii licenses, 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.
  

Yes, it does.

Jo, alles zu seiner Zeit. Wenn sich das alles ein bisschen beruhigt hat und ich ein bisschen Zeit habe kommt der Post auch nochmal auf Deutsch.

Naja das hier ist ja nicht die einzige Stelle wo ich das Feature angekündigt habe.

Gibt ja auch noch Twitter, YouTube, gbaTemp, verschiedene Discords, ... wo halt jetzt überall Kommentare und Fragen eintrudeln die ich lesen und beantworten will.
Und nebenbei dann noch die ganzen Server-Logs im Blick behalten ob auch alles so funktioniert wie es soll.

Aktuell nicht.

interesting...
- Which region did you use?
- What are your friend codes, so I can check the logs?
- Can you try again and see if pressing "the magic buttons" ( Up, 1, down, 2, right, minus, left, plus, B, A) makes the crash handler show up, and if so, can you send me a photo of that?

Found the bug, thanks a lot for reporting, will be fixed ASAP.

EDIT; Bug is now fixed.

Update: Mario Strikers Charged Football is now also supported by this method (PAL / USA / Japan only, not the Korean version).

Animal Crossing Wii is already on the "will probably never work" list.
