its not an error. GX does some check to see what IOSes are installed on your wii to prevent idiot noobs trying to use it with a stub IOS. to do these checks we use IOS36. some guides are having people install a patched IOS36 into 236. so it tries that first. if you don't have it, don't worry.
and if you people don't know what youre talking about, don't talk.
Thanks. I'm not a noob but i am not the best either. SO could you tell me how to install a patched cios 236. I think i know how but i wanna make sure. Is there a guide anywhere?
