Recently another method of storing ISO images have been created, letting you
store your ISO images onto a FAT filesystem.
This means you no longer need to partition your drive to have a WBFS
filesystem.
You just have to convert your ISO images into .wbfs files and store them in
a folder named wbfs on the root of your USB device.
You can use Wii Backup Manager to accomplish this.
Currently only Configurable USB loader & USB Loader GX support FAT
partitions.
转成WBFS格式了吗?还是USB Loader GX版本太低。
