thank you againYes you have two, maybe three options to do so.
The first one is USB Loader GX, that will allow you to load Wii Games from USB drives. That either be regular USB Sticks or Hard Drives.
If using USB Loader GX, you'll have to format it to a WBFS format in order to use the games in WBFS format.
The second one, and my personal favourite, is to use Configurable USB Loader.
This one allows you to load Wii games from SD Cards.
Just place the games in wbfs format, and load them with CFG Usb Loader.
I find this one much easier to use.
The third one is to use WiiFlow... but I don't know how to use it and I will never learn how to use it. It's too much trouble for what's worth in my personal opinion.
About USB Loader GX, I don't use that neither because I don't use USB drives.
If I might recommend you something, is to use CFG USB Loader.
