: It is a raw binary dump. If you are dumping from a real DSi, the dumper usually includes a "nocash footer" (containing CID and console ID) at the end of the file, which melonDS uses for decryption. File Naming
Browse and select your nand.bin file in the "NAND image" field. Click and restart the emulator. 3. Booting to Menu
When you play a standard DS game in melonDS with “DSi mode” disabled, the emulator only needs a basic firmware dump ( bios7.bin , bios9.bin , and firmware.bin ). But when you enable (required for DSi-exclusive games or enhanced features like the faster CPU), melonDS becomes a full DSi emulator. It expects to boot from a copy of the DSi’s NAND. That copy is nand.bin .
