Make sure your USB drive is formatted as FAT32 or NTFS. Flash drives should be usable too, but external hard drives are recommended as they are more reliable, and can store more games. To play games, we recommend using an external hard drive for your Wii. If you are not copying games using Wii Backup Manager, Witgui, or Wii Backup Fusion, make a folder on the root of the USB drive or SD card named “wbfs” and put the games in there. You can also use a development build of Dolphin, right click on a game, and use “Convert File” to convert it. If you want to play games that are in NKit format, use this program to convert them to ISO first. We recommend you copy games over with Wii Backup Manager if you use Windows, Witgui if you use macOS, or Wii Backup Fusion for Windows, macOS, and Linux. Make sure you have installed cIOS before following this! This is a quick start guide on how to use USB Loader GX, a popular USB loader for the Wii that’s used to play games from a USB drive.
