Nicksasa has released a NAND Flash Toolkit for the Nintendo Wii. Using this kit you can dump your Nintendo Wii's NAND to either a SD card or a USB device and then extract the contents of your NAND with the included Windows utility.
The process is a bit more involved then that as outlined in the quote below. The Wii's NAND is the internal flash that stores all of the System Menu, VC games, game saves, etc... It's a good idea to make a backup of your NAND before you start messing around with installing customization hacks as you can restore it using an Infectus chip if you brick it beyond repair.

To quote: This app dumps to USB and SD: If an usb device is plugged in it will dump to usb. If no usb device is inserted it will dump to sd ;)
To extract the dump you need your NAND AES KEY, you can get that by using Xyzzy. If you have runned xyzzy there is a file called keys.txt in the root of your sd card. Open it and look for NAND AES KEY.
Now make a folder called keys in c: and open your favorite hex editor and copy the NAND AES CODE from keys.txt into your hex editor and save the file as nand-key.bin in the keys folder.
Now just run "extract.exe" and select the nand-dump.img file and it will copy the .img file to the directory where the .exe is and extract it.
