Have you wanted to go online, yet miss Nintendo WFC after shutdown? Fear no more, as Wiimmfi is here to save the day!

Wiimmfi’s site is here.

Homebrew (Disc) Application

MrBean35000vr (you may know him as the creator of CTGP-R) has created a Wiimmfi Disc Patcher that allows you to insert a disc and let it automatically (temporarily; you have to run the patcher each time) patch the game for Wiimmfi use!

What you need


  1. Extract autowiimmfipatcher0.4.zip to the root of your SD: the apps and bslug folders must be on the root of SD.
  2. Go to Homebrew Channel, run the app, and insert your disc (you can insert it before or after launch, it doesn’t matter).
  3. Wait for patch to complete, and it’ll begin! Notice: The Mario Strikers Charged patch and Animal Crossing Wii fix are implemented in v0.4, so please do not worry.

ISO Patching

You may not want to run a patcher each time you want to play on Wiimmfi, and maybe you already use a USB Loader. As such, ISO Patchers were created, some for specific games.

What you need

  • Your copy of your game (WBFS, ISO, cISO, and other forms that a Wii can use are supported).
  • Wiimm’s Disc Patcher: You need this one if you’re patching Mario Kart Wii, this one if you are patching Animal Crossing Wii, or this one for any other.
  • A USB Loader, cIOS, and a USB to store the game on (you should already have these if you’re using a USB Loader)


  1. Extract the patcher of your choise to a folder, and place your copy of the game in it.
  2. Run the patch script for your OS: usually it will end in .bat for Windows and .sh for Mac/Linux.
  3. Once it’s finished, get the version out of the wiimmfi-images folder (it may be in the folder before the patcher - ../wiimmfi-images) and copy it back to your USB.

On the Fly Patching

Instead of patching the ISO you can use a USB loader which supports Wiimmfi.

What you need

  • Your copy of your game on your USB.
  • A USB loader which supports setting a Private WFC server like USB Loader GX.

Instructions (for USB Loader GX)

  1. On the loader’s main screen go to Settings (Gear icon).
  2. Select Loader settings.
  3. Search “Private Server” and change it to Wiimmfi.de.

WiiWare Patching

You’re able to patch WiiWare games in order to play them on Wiimmfi.

What you need

If you want to see how to use the WiiWare Patcher, click here!


  1. Download and extract the .zip of the latest version of Auto WiiWare Patcher, and put your WAD in it.
  2. Run the patch script for your OS: usually it will end in .bat for Windows and .sh for Mac/Linux.
  3. If it completed successfully, install the WAD that was made in wiiware-wads with Wii Mod Lite.

Mario Kart Wii Competitions

Wiimmfi allows you to participate in Mario Kart Wii competitions again.

What you need

Instructions (for Wii)

  1. Launch the original Mario Kart Wii game (not Wiimmfi patched).
  2. Navigate to Settings -> Network Settings (or Nintendo WFC Connection) -> Message Service. If you turned the message service feature on, turn it off and turn it on again.
  3. Launch the competition patcher. It will look for save files for Mario Kart Wii on your storage device, and upload them. This is done in case a missing competition is found in your save file.

If you’re using the Wii U, you will have to run the competitions patcher whenever you want to check for a competition, because WiiConnect24 is not enabled on the Wii U.

CTGP-R (Mario Kart Wii)

MrBean35000vr and Chadderz have an amazing CTGP-R distribution, the application that allows you to use a set of custom tracks, has automatic Wiimmfi patching. Go to the ChadSoft Website for the download and instructions.

MKW Hack Pack (Mario Kart Wii)

Huili has put together a really good collection of custom tracks and hacks called MKW Hack Pack, and it allows you to connect to Wiimmfi. To learn how to set it up, go to the wiki page.
