I am trying to download the homebrew channel

whenever i try copying the usa twilight hack it says file may not have been copied or file may not have been moved
what should i do

what version, and what save are you using? if you use the wrong firmware save it will say that.

how do i find out what version i have?

i used to have the twilight hack about a year and a half ago.
it worked until the part where it has all that junk after talking to the guy when you start the twilight princess game

look in tutorials there is an explanation on getting your version from the wii settings menu

Basicly are give you the info, if your wii is ~3.4 use twilight, if its 4.0+ use bannerbomb if 4.2 bannerbomb updated.
visit the site www.hackmii.com
get hackmii installer, if u can get bootmii nand and backup your wii.
need anything pm me are gladly help.
