I want to backup my wii games. I already have the homebrew channel installed. My wii is 4.3u. I read some guides on how to do this but it still looks complicated. Plus what hard drive should I get? How many gigabytes is enough? I have about 40 wii games plus I want to put everything that's on my SD card to the hard drive. Also I'd rather not have to pay an arm and a leg for it. What's a reasonable price?
