Note: If you don't have an SD Card, you can still accomplish most things using a Hard Drive formatted as FAT32 in place of an SD Card (SD is notably required for Bootmii and NAND backup). Make sure to always plug your hard drive into usb port0 - the one nearest the edge of the Wii. If you don't have an SD Card or Hard Drive, you can launch apps and install WADs over WiFi to your Wii from your PC. Just open apps (boot.dol\elf files) or WADs with ModMii. Note that some apps may not work properly or support all features if they require an SD or HDD and you should never attempt to change the region of a console via WiFi.

1. First, insert your SD Card into your PC and determine if it needs to be formatted by checking the current Format\File-System of the SD Card.


• Open "This PC" or "My Computer", right-click the SD Card you want to use, then select "Properties".
  • If "This PC" or "My Computer" is not on the desktop it can be accessed using the ⊞ Win+E keyboard combination.
• Make note of the Drive Letter of the SD Card as this will be important later.
• If the "File-System" is already FAT32, you can skip this step.


2. If you have anything saved to the SD Card, you should back it up now as all the data will be lost once you format it.


3. Launch FAT32 GUI Formatter from shortcuts on your Start Menu or Desktop.


• Carefully select the correct drive letter corresponding to your SD Card.
• You may optionally uncheck the "Quick Format" box, then click "Start".
  • When completed it should display "Done".
  • If you get an error indicating the device is in use, try again after first closing all of your file explorer windows, even the ones that weren't browsing the device.
    
• Click the "Close" button.


4. Copy the files ModMii downloaded to your SD Card.
