OK, as promised, here is the guide to CustomizeMii (if anyone wants a guide to doing it without CustomizeMii, using purely cross-platform tools, ask and I should be able to post it in a few days).
DISCLAIMER: MAKE SURE YOU HAVE BRICK PROTECTION ON YOUR WII BEFORE INSTALLING ANY CUSTOM CHANNEL.
First off, you need to download and run CustomizeMii. Get it here: [
code.google.com]
Download and extract the RAR, and run CustomizeMii. You should be greeted by a window like this:

You'll see there is a list of "Base WADs". These are fully legal WADs created by various members of the Wii scene, which CustomizeMii modifies to create channels. (This means that usually the animation in final channels is the same as that in these channels, but with different images). You need to choose a channel with an
animation you like. *Note: You will change the images, and the sounds if you want, but the actual animation of images will remain the same*
For this tutorial I will use WADder Base 1. (You can use the "Preview" button to view YouTube videos of the various base WADs). As you can see if you watch this video : [
www.youtube.com] this channel has a non-moving background, and an image in the foreground which "grows" (i.e. is scaled larger).
Once you have chosen the base WAD you want, click it and press Load. This will download the WAD and allow you to start editing it. (Alternatively, you can choose Save, and then the next time you want to use this base WAD to make a channel, you will not have to download it again).
Now the fun starts :). It's time to start editing. First, go to the "Title" tab. This one is fairly straight forward, simply type in the Title you want to appear when you hover over the channel in the System Menu, like so:

Next, move over to the "Options" tab. There are a few things to note here. First off, you will want to change the title ID of the channel. The title ID is the unique 4-letter ASCII string which identifies your channel. Make sure it doesn't clash with another channel (all official channels start with H, so just avoid it and you'll be fine).

Next, you need to click the "Forwarder" button, and then choose "Simple Forwarder" (advanced forwarder is understandably more complicated), and type in the name of folder within "apps" that the boot.dol is found in (e.g. "homebrew_browser")

Now for sound. If you want your channel to have a sound, it is best to click the "Browse" button beside the "New Sound" box, and then choose "Convert to BNS" (converting to BNS will mean a smaller file size for your channel). Then simply choose your sound file and click convert.

Finally, on to editing the banner. Move over to the "Banner" tab, and you'll see all the images ("TPLs") in your Base WAD. These are the images you can replace. You can use the "Preview" button to see what the images are, then use the "Extract" button to extract the images as PNG images. These can then be edited with any image editing program (e.g. PhotoShop, Paint.NET, GIMP). Once you're done, use the "Replace" button and choose the edited image. !!MAKE SURE THE IMAGE HAS THE SAME DIMENSIONS AS ORIGINAL!!.

Last thing that needs done if the icon. This process is identical to the "Banner" process, only under the "Icon" tab. Should be straight forward.
Then you're done. Click the "Create WAD" side of the big button at the bottom of the CustomizeMii window, choose where to save it and give it a minute to package it all up.
You now have a fully legal, custom, forwarder channel. Can't give you help with installing, but I'm sure you can work it out ;)
This may seem like a lengthy process, but really, apart from the image editing, which could take a while depending on how much detail you want etc., it takes about a minute. I hope you can follow this guide, if there are any parts which are unclear please give me a shout and I'll try to clarify. Also, if people notice any mistakes, please tell me so I can correct them.
Note: It
is also possible to edit the actual animation, as well as just the images, but this is a far more advanced topic, and shouldn't be attempted by beginners. Its much easier to use the animations others have made and just replace the images.
