Unique encryption keys (found in keys.bin ) that tie that specific NAND to your specific hardware. The Dangers of Using a "Free" Downloaded NAND
Having a NAND dump is essential for Wii owners, as it allows them to back up their console's data and restore it in case of a system failure or when upgrading to a new console.
Understanding the motivation is key. Most users search for this for three primary reasons:
