That first video is good, and also the second one from the same guy that continues with the installation of the USB hard drive. I got both of those done with no problem. I got a bunch of Wii games down onto the hard drive then the Wii stopped reading discs so I have to deal with that now. I had a feeling it was going to go based on some of the noises it was making.
Is there a good way to play Gamecube games on the Wii if they are also stored on the USB hard drive? I saw the thing called Dios Mios but it seems a bit iffy. It might be the only way. Right now I have the Gamecube hooked up anyway but it would be nice to take a box out to clean things up.
I haven't gotten to the other emulators for the homebrew channel yet, hope to get to that over the holidays.
