I got AnyRegionChanger to get the japanese nintendo channel, and it all went smoothly. I then used the Menu Loader so I could boot the channel, but it's giving me a 117404 WiiConnect 24 error. My US Nintendo Channel also had that same error a few minutes ago, but it has now disappeared. The error says that WiiConnect24 is not available right now, and that I should wait a while for it to be available again. Is this normal right now for jap. channels? Or is it caused because it's on my US Wii?
