The Wii’s NAND (Negated AND or flash memory) is not merely a storage device; it is the console’s digital soul. A complete NAND dump contains everything: the System Menu, IOS (internal operating systems) versions, Miis, save files, downloaded WiiWare and Virtual Console titles, browser history, and even console-specific encryption keys. Unlike a ROM cartridge, which is a fixed snapshot, a NAND is a living, breathing digital environment. Two Wiis are never truly identical. The challenge for preservationists is that this chip is notoriously fragile. Through normal wear, failed system updates, or simple voltage fluctuations, a Wii can “brick,” rendering the entire console inoperable. When that happens, the unique digital history of that machine—the high-score data, the novelty Mii of a grandparent, the purchased but undownloaded game—vanishes forever.
