Wiimmfi Logo

Wiimmfi is a replacement service for the now-defunct Nintendo Wi-Fi Connection.

Wiimmfi’s site is here.

Homebrew (Disc) Application

MrBean35000vr (creator of CTGP-R, a Mario Kart Wii content pack) created a Wiimmfi Disc Patcher that allows you to insert a disc and patch the game on-the-fly for Wiimmfi use, though this must be run every time you start the disc.

What you need


  1. Extract Auto Wiimmfi Patcher and put it in the apps folder on your SD Card.
  2. Insert your SD Card into your Wii, and launch Auto Wiimmfi Patcher from the Homebrew Channel.
  3. Insert your game disc (you can insert it before or after launch, it doesn’t matter).
  4. Wait for patch to complete, and it’ll begin!

No-Homebrew (Disc)

Thanks to Fullmetal5’s FlashHax, MrBean35000vr created a Wiimmfi Disc patcher for the Internet Channel.

What you need

  • A Wii with an Internet connection
  • Internet Channel


  1. Insert your game disc.
  2. Make sure your Wii is in 60Hz mode in the system settings.
  3. Open the Internet Channel and go to this page.
  4. Add that page to favorites by pressing the “Add Favorite” button.
  5. Close the Internet Channel and return to the Wii Menu (you can also use the Reset button).
  6. Open again the Internet Channel and go to your favorites and click on “Wiimmfi”.
  7. Wait until the game starts.

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 other Wii games such as Super Smash Bros: Brawl.
  • 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 choice 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.

WiiWare Patching

You can patch WiiWare games in order to play them on Wiimmfi.

What you need

  1. 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. Extract Mario Kart Wii Competition Patcher and put it in the apps folder on your SD Card.
  2. Insert your SD Card into the Wii.
  3. Launch the original Mario Kart Wii game (not Wiimmfi patched).
  4. 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.
  5. Launch Mario Kart Wii Competition Patcher.
  6. The patcher will look for save files for Mario Kart Wii on your storage device in various places, and upload them. This is done in case a missing competition is found in your save file. It will also, of course, patch your Wii for competitions.

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.
