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).
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.
Thanks to Fullmetal5's str2hax exploit, which Leseratte was able to adapt for the Wiimmfi patcher, you can run the Wiimmfi patch without having any homebrew on your Wii.
4. Confirm that you do want to use WC24 and the shop channel
5. The Wiimmfi patcher page should show up. 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
7. The game should now start with the Wiimmfi patch included
There's an easy method to patch games to use Wiimmfi that can be used whether or not you have homebrew on your Wii. It works on some older games, such as Mario Kart Wii and Super Smash Bros. Brawl, but not every game.
If you are already using USB Loader GX, try updating it to the most recent version. Then, there should be a "private server" setting (both in the global loader options and in the game options) which you can set to "Wiimmfi" to make the USB Loader automatically patch every game you start to work with Wiimmfi.
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.
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 patcher for your game.
3. 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.
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. 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.
Wiimmfi doesn't only support Wii games, it supports lots of DS games too. Thanks to an exploit called nds-constraint, you can play DS games online without patching your games.
Getting a Wi-Fi network with WEP or no security is the hardest part, because DS games don't support newer Wi-Fi security types. However, many routers support creating a guest Wi-Fi connection, or you can make a hotspot on your phone or your computer. There are plenty of resources on the Internet that have information on this, so use your favorite search engine to find them.
{: .notice--info}
Some games are DSi enhanced which means you can play games online without having only WEP or no security on your router if you have a DSi or 3DS. Pokémon Black and Pokémon White are DSi enhanced. In order to make use of it, follow the instructions below via the DSi or 3DS Wi-Fi settings. Those are separate from the DS Wi-Fi settings.
If you get error 20110, that means your ISP (Internet Service Provider) or network is blocking the use of a DNS. You can use our [DNS-Server](https://github.com/RiiConnect24/DNS-Server/releases/latest) program to bypass this.
You cannot use Sudomemo, which revives Flipnote Studio on the DSi, if you're using this DNS. If you want to use Sudomemo instead of playing games on Wiimmfi, you will have to set your primary DNS to `104.248.0.110` on Wi-Fi settings on your DSi or 3DS, not the DS Wi-Fi settings. Or you can use their [DNS-Server](https://github.com/Sudomemo/sudomemoDNS) program.
MrBean35000vr and Chadderz have a custom track distribution called CTGP-R that allows you to use a set of custom tracks and has automatic Wiimmfi patching. Go to the [ChadSoft website](http://chadsoft.co.uk) for the download and instructions.
PhillyG has put together a collection of custom tracks and hacks called MKW Hack Pack, and allows connections to Wiimmfi. To learn how to set it up, go to the [wiki page](http://wiki.tockdom.com/wiki/MKW_Hack_Pack).
Wiimm and Leseratte make a custom track distribution called "Wiimms MKW Fun", which gets updated about three times a year. It is based on the LE-CODE framework by Leseratte, has Wiimmfi support, and lots of other features. You can find out more about it on its [wiki page](http://wiki.tockdom.com/wiki/Wiimms_Mario_Kart_Fun).

RiiConnect24 allows you to use discontinued services from WiiConnect24, which include the News, Forecast, Everybody Votes, Nintendo and Check Mii Out Channel, along with Wii Mail. This is optional to install.
