In the context of melonDS, this file allows the emulator to replicate the DSi's hardware environment accurately rather than just launching individual ROMs. Why You Need It Once inside GodMode9i, press the Home button to
Why melonDS needs nand.bin
The nand.bin file cannot function in isolation. Full low-level emulation (LLE) of a DSi requires a matching set of four system files to establish a secure, decrypted cryptographic handshake: Required File Name Intended Console Role Exact Data Size DSi ARM7 Core Engine Boot Loader bios9.bin DSi ARM9 Main Processor Boot Loader firmware.bin Operational Operating System Layer nand.bin Internal Flash Storage File Allocation Getting DSi/DSiWare games to work in melonDS - RetroPie
