You can download metadata or manage installed DSiWare applications directly from this menu. Troubleshooting nandbin Issues
To achieve the best results, you must locate or generate your own NAND dump.

melonDS, aiming for cycle-accurate emulation, requires the actual firmware code to function correctly. By providing a valid NAND bin (or specifically, the firmware binaries extracted from it), the emulator boots the exact same code that runs on a physical DS/DSi unit. This resolves timing issues, fixes touch-screen calibration bugs, and allows for the full boot process (the "Nintendo DS" splash screen).
Open the app and navigate to Config -> Emu Settings . Set Console Type: Change the console type to DSi . You can download metadata or manage installed DSiWare
The SDMMC controller ( DSi_SDHost ) serves as the interface between the DSi system and the NAND storage, handling commands, data transfers, and status reporting. The DSi_MMCStorage class then processes MMC commands and translates them into operations on the NAND image.

Inside the Melonds folder, create a new folder named exactly: nandbin Note: Some "Top" guides suggest placing this at SD:/nandbin/ instead. Stick with the emulator’s default ( /3ds/Melonds/nandbin/ ) for compatibility with the latest release.
If you tell me you're getting (if any), or whether you're using Windows or Android , I can provide more specific troubleshooting steps.
