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 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.
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 23400, your ISP or network is blocking the use of a custom DNS.<br>
To solve this issue, Wiimmfi has a custom DNS server that can be ran on your PC - you can read about it [here](https://wiimmfi.de/patcher/dnspatch#customdns).
1. 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 `95.217.77.181`, and your secondary DNS to `1.1.1.1`.
1. Let the connection test finish, and do not perform a Wii System Update.
1. Launch your game through the Disc Channel - it should now be patched with Wiimmfi.
A method for Wiimmfi patching which runs on retail game discs, but must be manually launched via the EULA User Agreement (derives from [str2hax](str2hax)). Due to the nature of this process, it can be ran on Wiis without homebrew.
1. 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`.
1. Let the connection test finish, and do not perform a Wii System Update.
1. Go back twice to `Internet`, and press `User Agreements`. Then, confirm that you would like to use WC24 and the Wii Shop Channel.
1. 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.
1. Wait a while for the patcher to load (usually about 1.5 minutes) and the inserted game should boot with a Wiimmfi patch.
If you run into UPnP-related issues (such as the patcher getting stuch at "Init network..." or "add UPnP port forward" steps for more than 10 seconds), you can press the - button on your Wii Remote, or the Y button on your GameCube controller as soon as the patcher loads to circumvent this.
A method for Wiimmfi patching which runs on retail game discs, but must be manually launched via the Internet Channel (derives from [Flashhax](flashhax)). Due to the nature of this process, it can be ran on Wiis without homebrew. [This](wiimmfi#manual-disc-patching-via-eula-user-agreement) method is generally more reliable, and is recommended instead.
1. Extract the .zip of the latest version of WiiWare Patcher, and put your WAD in it.
1. 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.
1. If it completed successfully, install the WAD that was made in `wiiware-wads` with YAWM ModMii Edition.
1. Download the patcher and extract the `.zip` file.
1. 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`.
1. 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`.
