The NAND (Negative-AND) flash memory is the built-in storage on the Wii console, housing the system menu, installed channels, and save data. A or NAND Backup is a complete, bit-for-bit image of this memory, typically saved as a .bin file on an SD card. This archive includes: The System Menu: The main interface.
| Partition | Purpose | |-----------|---------| | | Read-only ROM – first code executed on power-on | | Boot1 | Slightly updatable bootloader – verifies Boot2’s signature | | Boot2 | The true system loader – loads IOS and System Menu | | SLC (NAND) | Main storage – includes /shared1 , /shared2 , /title , /sys , /ticket , etc. | | ECC area | Error-correcting codes (not user-accessible) |
Once unpacked, you can manually backup individual files, such as your Wii Message Board history, or your virtual console saves, isolating them from the heavy raw binary image. The Legal and Ethical Landscape of Public Archives wii nand archive
Dolphin Emulator allows you to emulate your specific Wii, including all your purchased channels and saves. Open Dolphin Emulator. Click on the tab. Select Manage NAND .
Once completed, remove the SD card and insert it into your computer. Look for two critical files in the root directory: nand.bin (The actual 512MB image of your console) keys.bin (The unique decryption keys for your console) The NAND (Negative-AND) flash memory is the built-in

Once completed, turn off the console and take the SD card to your computer. You will find two files: nand.bin (The actual memory archive) keys.bin (The unique keys for your console) Using Your NAND Archive in Dolphin Emulator
Once finished, remove the SD card and plug it into your computer. You will see two critical files: nand.bin (the actual storage image) and keys.bin (your console's unique cryptographic security keys).
