[Wiimmfi](https://wiimmfi.de) is a replacement service for the now-defunct Nintendo Wi-Fi Connection. 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 lots of different methods to connect to Wiimmfi. Choose the one that fits your needs best.

If you get the error 23904 while connecting to Wiimmfi, then you are using an outdated patch.<br> Follow the steps below for the method you're using to connect to Wiimmfi again.<br> See [this page](https://wiimmfi.de/update) for more details.<br>

### Automatic patching from the Disc Channel using Priiloader

If you see the hack `Wiimmfi patch v2` or `Wiimmfi patch v3` instead, then you do not have the latest version of the hacks_hash.ini file, and you need to [re-install Priiloader](priiloader). 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.

#### Requirements
+ A Wii with an internet connection, on System Menu version 4.3
+ [Priiloader](priiloader) 0.9 or later

    ![](/images/priiloader/mainmenu.jpg)

1. Go to `System Menu Hacks`. If you are using 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}
1. Make sure the `Wiimmfi patch v4` hack is enabled.

    ![](/images/priiloader/hacks.jpg)

1. Go to `Change Settings`.
1. Return to the main menu, and press `System Menu` to return to the Wii Menu.
1. 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.

### Automatic patching using a USB Loader

There's an easy method to patch games to use Wiimmfi that can be used whether or not you have homebrew on your Wii.

#### Requirements

+ Mario Kart Wii Competitions
+ [A Wii with Priiloader 0.9 or later installed](wii-loaders)

#### 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`.
1. Set the option to `Wiimmfi` and save the settings. By default, games should now be automatically patched for Wiimmfi.

### Automatic Disc Patching via Custom DNS

A method for Wiimmfi patching which runs on retail game discs automatically through the usage of a custom DNS server. It works on some older games, such as Mario Kart Wii and Super Smash Bros. Brawl, but not every game. Due to the nature of this process, it can be run on Wiis without homebrew.

If you get error 20100 or 20110, that means the game is too new for this method.
{: .notice--warning}

1. The game should now start with the Wiimmfi patch included

1. Go to `Page 2`, then click on `Internet`. Confirm that you do want to use WC24 and the shop channel

{: .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](flashhax)).

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

#### Instructions

1. Open the following webpage in the Internet Channel: `http://chadsoft.co.uk/wiimmfi`

1. Hold the RESET button while turning on your Wii.
1. Open the Internet Channel again and access the favorite you just made.
1. It should be patched with Wiimmfi. Be patient, as Flashhax can be very unreliable - it may take several tries to get right.

{: .notice--info}

### Manual Disc Image Patching via PC

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

#### Requirements

+ A computer with Windows on it (or using Mono or Wine on Mac/Linux)
+ 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

#### Instructions

1. Download the patcher and extract the `.zip` file.
1. Insert your SD card or USB drive into the Wii.
    + 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`.
1. If the above was successful, you should see a window pop-up that displays the patching process. Once it's finished, get the version out of the `wiimmfi-images` folder (it may be in the folder outside of the patcher - ../wiimmfi-images) and copy it back to your USB.
