Go to http;//code.google.com/p/sneek/ and copy the SNEEKInstallerv0.6c-cred.rar. Unrar this to your harddisk.
I created a sneekinstaller folder and copied the package files to that location.
I also created 4 extra folders under the sneekinstaller folder:
sneekfiles iosfiles SD USB.
Run the sneekinstaller.exe program. Wait a few seconds while the scam message counts down. Hit the Ok.
Now hit the sneek files browse button and select the c:\sneekinstaller\sneekfiles
Next, hit the ios files browse button and select the c:\sneekinstaller\iosfiles
Finally hit the SD device Browse button and select the c:\sneekinstaller\SD
Select "Sneek Type" Uneek+DI . The usb browse button now becomes available as well.
Choose the USB device Browse button and choose c:\sneekinstaller\USB
Now, Hit the Sneek files "Get Files" button. It should download the files from the internet. (So that needs to be available on your pc.)
And Hit the Iosfiles "Get Files button. Again, it should download some files from the internet.
Now, you should overwrite the c:\sneekinstaller\sneekfiles with those from the cdi package.
So, you will overwrite dimodule.elf, esmodule.elf, fsmodule-usb.elf and fsmodule-sd.elf
Finaly hit the SNEEK setup "install SNEEK" button.
In the SD and USB folders, you will find the new kernel.bin and di.bin that you will need on your wii sd card and harddisk.
In your usb sneek folder, you will also need the font.bin file. That one can be downloaded from the http;//code.google.com/p/sneek website as well.
I assume you already have a working uneek setup. Simply copy the kernel.bin and di.bin you just created over the existing ones.
It's possible with this version to have several different nands on your usb drive. Simply create a nands folder on it.
Under that folder, create some subfolders nand01, nand02, ....Copy all your nand folders under such a subfolder.
Uneek + cdi will now automatically use the nand in the subfolder. In the uneek overlay menu, if you hit the '+' settings, you have a nand selection option. Everything should however still work with your nand folders in the root of your usb drive as well.
I hope I haven't forgotten anything in my explanantion. Just let me know how it works out.
The way to create a working nand is described pretty well in my sneaky poor man's backup tutorial in the wii tutorial section here.
