Have you softmoded your wii according to this site's guide?
I am having trouble with USB loader Gx. It says I need cios222 or 249. I thought I had installed it but I didn't. I'm a noob when it comes to this stuff so if anyone can tell me what exactly I need to do to fix this issue it would be great.
Well, you should at least not have your current error saying you don't have 222 or 249 (cause you will). Doesn't mean you won't have other issues. We'll tackle those if they occur.
