Wiimmfi

{% include toc title="Table of Contents" %}

Nintendo Wi-Fi Connection was an online multiplayer gaming service for the Wii, allowing free online play. While different games were supported for longer than others, all games are no longer able to play through conventional means as of August 2023. To regain Nintendo WFC functionality, this guide provides instructions on installing Wiimmfi. There are several different methods to connect to Wiimmfi listed in order of least to greatest difficulty - choose the method that suits your situation best.

If you get error 23904 while connecting to Wiimmfi, then you are using an outdated patch.
Follow the steps below for the method you're using to connect to Wiimmfi again.
See this page for more details.

Automatic patching from the Disc Channel using Priiloader

If the Wiimmfi Patch displays as anything other than v4, you do not have the latest version of the hacks_hash.ini file and the patch will not work. You must reinstall Priiloader, the guide to which can be found in the requirements section. {: .notice--warning}

A method for Wiimmfi patching which runs on retail disc games automatically via the Disc Channel.

What you need

• A Wii with an internet connection, on System Menu version 4.3
• Priiloader 0.9 or later

Instructions

1. Hold the RESET button while turning on your Wii. If you are using a Wii mini, plug in a USB keyboard and hold Escape while turning it ON.

2. You should see the Priiloader menu.

   

3. Go to System Menu Hacks. If you used a USB drive to install Priiloader, make sure you do not have an SD card inserted at the same time. This will cause Priiloader to be unable to find the hacks_hash.ini file. {: .notice--info}

4. Make sure the Wiimmfi patch v4 hack is enabled.

   

5. Scroll to Save Settings and save your changes.

6. Return to the main menu, and press System Menu to return to the Wii Menu.

7. Launch your game through the Disc Channel - it should now be patched with Wiimmfi.

Homebrew (Disc) Application

A method for Wiimmfi patching which automatically patches game backups in the latest versions of USB Loader GX or WiiFlow Lite.

What you need

• A Wii with an internet connection
• USB Loader GX or WiiFlow Lite

Instructions

1. Open the game or global settings for your specific USB loader and search for the Private Server option. By default, it will be set to Off.
2. Set the option to Wiimmfi and save the settings. By default, games should now be automatically patched for Wiimmfi.

No-Homebrew (Disc)

A method for Wiimmfi patching which runs on retail game discs automatically through the usage of a custom DNS server. While convinient, it only works with a small selection of games including Mario Kart Wii and SSBB. Due to the nature of this process, it can be run on Wiis without homebrew.

If you get error 20100 or 20110, the game you are trying to play is not supported by this method. {: .notice--warning}

If you get error 23400, your ISP or network is blocking the use of a custom DNS.
To solve this issue, Wiimmfi has a custom DNS server that can be ran on your PC - you can read about it here. {: .notice--warning}

str2hax Method

2. Scroll down to save settings and press A, then press B to go back to the main menu of Priiloader.

ISO Patching

A method for Wiimmfi patching which runs on retail game discs, but must be manually launched via the EULA User Agreement (derives from str2hax). Due to the nature of this process, it can be ran on Wiis without homebrew.

What you need

• A Wii with an internet connection

Instructions

1. Insert your game disc.

2. Go to Wii Settings > Internet > Connection Settings and select whatever connection you are using. Then, Change Settings > Auto-Obtain DNS NO > Advanced Settings. Set your primary DNS to 95.217.77.151, and your secondary DNS to 1.1.1.1.

   

3. Scroll down to save settings and press A, then press B to go back to the main menu of Priiloader.

4. Go back twice to Internet, and press User Agreements. Then, confirm that you would like to use WC24 and the Wii Shop Channel.

5. The Wiimmfi patcher page should now display. If it doesn't, and you still see the default license agreement, your router might not be compatible with this method.

6. Wait for about 1 minute and 30 seconds for the patcher to load

WiiWare Patching

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. {: .notice--warning}

A method for Wiimmfi patching which runs on retail game discs, but must be manually launched via the Internet Channel (derives from Flashhax). Due to the nature of this process, it can be ran on Wiis without homebrew. This method is generally more reliable, and is recommended instead.

Instructions (for Wii)

• A Wii with an internet connection, running in 60Hz mode
• The Internet Channel

Instructions

1. Go to Wii Options.
2. Go to Wii Settings.
3. Go to Page 2, then click on Internet.
4. Go to Connection Settings.
5. The Wiimmfi patcher should begin. Be patient, as Flashhax can be very unreliable - it may take several tries to get right.

Mario Kart Wii Competitions

If you get error 20100 or 20110, that means the game is too new for this method.

Requirements

• An SD card
• Your copy of your game (in WAD format)
• WiiWare Patcher (cross platform)
• YAWM ModMii Edition

If you want to see how to use the WiiWare Patcher, click here! {: .notice--info}

Instructions

1. Extract the .zip of the latest version of 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. If you're using the RiiConnect24 Patcher, select your device (Wii, vWii, or Dolphin) and choose the WiiWare patcher.
3. If it completed successfully, install the WAD that was made in wiiware-wads with YAWM ModMii Edition.

DS Games

A method for Wiimmfi patching which runs on game disc images, but must be manually run on a PC via a script.

MKW Hack Pack

• A Linux/macOS/Windows PC with an internet connection
• A copy of the game you want to patch - supported formats are ISO, WDF, WIA, CISO (=WBI), WBFS, GCZ, and FST - NKIT is NOT supported
• Wiimmfi ISO Patcher

Instructions

1. Download the patcher and extract the .zip file.
2. Open the extracted folder and copy your Wii game images into it.
   • If you're on Windows, double-click the patch-images.bat file (this may also be displayed as "patch-images" Batch File). If you run into Cygwin-related issues, try the patch-images-32.bat file instead.
   • If you're on MacOS, open a command line prompt in the current folder, make the shell script executable through the command chmod +x *.sh and then execute ./patch-images.sh.
   • If you're on Linux, double-click the patch-images.desktop file (this may also be displayed as "Patch Images") or execute the ./patch-images.sh file in a terminal after making it executable through the command chmod +x *.sh.
3. If the above was successful, you should see a window pop-up that displays the patching process. Once the process finishes, you will find the patched images in a folder called wiimmfi-images.
