The nand.bin file is a raw byte-for-byte copy (a dump) of the internal flash memory (NAND) found inside a physical Nintendo DSi console.

The only legal way is to using custom firmware (like Unlaunch + dumpNAND). You cannot download it from websites — that’s piracy and against emulator policies.

The term "nand.bin" refers to a file often associated with Nintendo DS emulation. The Nintendo DS uses a NAND (flash memory) storage for saving data, similar to how modern devices use storage for data. In the context of emulation, a "nand.bin" file can represent a dump of this storage, which includes various game saves, system settings, and sometimes even DSiWare and other downloaded content.

This security architecture is why melonDS strongly encourages users to dump the NAND from their own personal consoles using homebrew tools like dsidump or FWTool . It ensures that the emulator can decrypt the specific file structure intended for that unique set of hardware keys.
