1. Place your NAND dump in the Root of the SD card or USB device. It should contain these folders:
2. Download the Mighty Channels beta and extract the mighty_channels folder from the Zip to the Apps folder on the SD card.
3. On your Wii, go to the Homebrew Channel and Load Mighty Channels.
4. In the main menu, you get the choice between Real NAND, SD NAND and USB NAND. Select the location to load games from.
5. On the next screen, choose the game to load (point and press A), then press A again to play!
By default, no images are loaded, making the interface looking a little less good than it could be. You have to manually download the images.
The easiest way is by pressing Home in the game select screen, then selecting "Download images".
If you don't have an Internet connection on the Wii, you must download the images manually from http://wiitdb.com.
Images must be placed in the SD:/config/mighty/channels/ (or USB:/....). Don't rename the images from WiiTDB or it won't work.
Using Meta.XML arguments
The arguments of the Meta.xml for Mighty Channels can be used to determine the IOS slot to use (for cIOS that can be installed in any slot) and to autoboot a certain NAND choice.
The argument to change the IOS slot is --ios=123, where 123 needs to be replaced by the correct slot (Usually 249).
The argument to change the default NAND option is --auto=USB where USB can be replaced by SD if needed.
Arguments are added to the meta.xml like this:
