### 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.

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

#### Voraussetzungen

1. Gehe zu `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.

### 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.

#### Voraussetzungen

### 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.

#### Menü

+ Ein Computer mit Windows (oder nutze Mono oder Wine auf macOS/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
+ [ISO Patching](https://download.wiimmfi.de/patcher/wiimmfi-patcher-latest.zip)

#### Instructions (for Wii)

1. Download the patcher and extract the `.zip` file.
1. Your copy of your game (WBFS, ISO, cISO, and other forms that a Wii can use are supported).
    + 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.
