If you searched for this exact phrase, you may be looking for a specific download or patch. As of now, there is no official “Nandbin Edition” of melonDS. Instead, the phrase refers to a wave of new updates to the main melonDS repository (version 1.2 and the nightly builds) that incorporate Nandbin’s findings.
melonDS uses the NAND dump to enter DSi Mode. Without a valid NAND, the emulator defaults to standard DS mode (similar to a Nintendo DS Phat/Lite).
Key Requirements for Functionality: To use a NAND file in melonDS, three specific components are required:
Configuration Steps:
Just tried the latest nandbin/melonDS update — big quality-of-life improvements and bug fixes that make emulation smoother and more reliable. Highlights:
If you use nandbin or melonDS for homebrew or dump management, this release is worth testing — back up your NAND first, try importing an image, and report any issues to the project's issue tracker so maintainers can follow up.
Unlocking DSi Mode: The New Guide to nand.bin for melonDS For enthusiasts of Nintendo handheld emulation, the nand.bin file is the holy grail for melonDS. While the standard Nintendo DS mode works out of the box with built-in BIOS replacements, accessing the full power of the Nintendo DSi—including the DSi Menu, DSiWare, and experimental online features—requires specific system files from a real console.
This guide explores everything you need to know about setting up a "new" nand.bin for melonDS in 2026. What is nand.bin?
The nand.bin file is a digital image of the internal flash memory (NAND) from a Nintendo DSi. It contains the system’s operating system, saved settings, and any installed DSiWare games. Unlike standard ROMs, this file is uniquely encrypted for each individual console, which is why melonDS requires it to accurately simulate the DSi environment. Essential Requirements
To run melonDS in DSi mode, you need a specific set of files typically dumped from a physical DSi: nand.bin: The internal storage image.
dsi_bios7.bin & dsi_bios9.bin: The ARM7 and ARM9 BIOS files. dsi_firmware.bin: The system firmware.
Note: If you are using the RetroArch melonDS DS core, these files often need specific names like dsi_bios7.bin and dsi_nand.bin. Step-by-Step Setup Guide Follow these steps to integrate your nand.bin into melonDS:
Dumping your Files: Use tools like dumpTool on a modded Nintendo DSi to create a backup. The process typically takes about 7 minutes and produces a folder containing your unique nand.bin. Configure melonDS: Open melonDS and navigate to Config > Emu settings. Go to the DSi mode tab. Set the "Console type" to DSi.
Link your nand.bin and the accompanying DSi BIOS files in their respective path fields.
Booting the Firmware: To see the DSi menu, go to System and select Run with no ROM loaded (or "Boot Firmware"). Managing DSiWare
One of the best "new" features of melonDS is the DSiWare Manager. This allows you to import .nds files directly into your virtual NAND: How to install a title to nand? · Issue #2023 - GitHub
To use DSi features, you must obtain a NAND dump from a physical Nintendo DSi. Dumping: Use a homebrew tool like dumpTool on a hacked DSi.
Resulting File: The tool will generate a folder (typically named DT######...) containing nand.bin, which is roughly 240MB.
decryption: The NAND is typically dumped with a "nocash footer" at the end (offset 0xFF800), which includes the console's unique ID and CID required for decryption. 2. Setup in melonDS
Once you have your nand.bin, follow these steps to enable DSi mode:
Organization: Place the nand.bin along with bios9i.bin, bios7i.bin, and firmware.bin into your emulator's system folder. Config: Go to Config > Emu Settings > DSi Settings.
Directing Paths: Point the emulator to your nand.bin file. You should also ensure the DSi BIOS and Firmware paths are correctly set.
Booting: In the main menu, select System > Boot Firmware (DSi) to launch the DSi Home Menu. 3. Managing DSi Titles (Newer Features)
Newer versions of melonDS (0.9 and above) include a DSi Title Manager that allows you to install DSiWare directly to your emulated NAND.
Navigate to System > Manage DSi titles (ensure the emulator is stopped/not running a game). Click Import title... and select your DSiWare ROM.
Select Download from NUS to automatically fetch the necessary metadata.
Once installed, the game will appear as a "gift" package on the DSi Home Menu next time you boot the firmware. 4. Key Differences: DS vs. DSi Mode
In the context of the melonDS emulator, nand.bin is the raw storage image of a Nintendo DSi's internal memory (NAND). While standard DS games don't require it, this file is essential for emulating DSi Mode, which allows you to run DSi-exclusive titles (DSiWare) and access the system's internal menu. The Role of nand.bin in melonDS
For melonDS to function in DSi mode, it needs a set of specific system files dumped from an actual console:
nand.bin: Contains the operating system, installed DSiWare, and system settings.
bios7i.bin & bios9i.bin: The ARM7 and ARM9 BIOS for the DSi. firmware.bin: The DSi's firmware. Recent Updates and Features
As of 2026, melonDS has significantly improved its DSi integration:
Standalone vs. Core: While the RetroArch melonDS DS core is often used, the standalone version provides more direct control over system settings.
DSiWare Management: Newer versions include a built-in DSiWare manager, making it easier to install titles directly to your nand.bin file without third-party tools.
Region Recognition: The emulator now more accurately detects the region of your NAND (J, E, or U), which is critical for compatibility with specific system apps. Setting Up a New nand.bin
If you are starting fresh with a new nand.bin in melonDS, follow these general steps found in community guides:
Placement: Place your nand.bin, BIOS, and firmware files in the emulator's system folder.
Configuration: Go to Config > Emu Settings > DSi. Ensure the paths point correctly to your dumped files.
Console Type: Change the "Console Type" from DS to DSi in the settings.
Booting: You can choose to "Boot into the DSi Menu" or boot a game directly. If the screen hangs white, try disabling JIT (Just-In-Time) compilation, as some NAND dumps are delicate. Important Considerations
Legality: NAND files are copyrighted material. Distributing them is considered "warez" and is prohibited on official forums. You should dump these from your own physical hardware using tools like dumpTool.
File Size: A standard DSi NAND dump should be exactly 251,658,304 bytes.
Savestates: Relying on savestates in DSi mode can be risky during updates, as core changes often break compatibility; it is safer to use the internal game save system.

Now, let's talk about the file that broke the camel's back: NANDBin.
In raw emulation terms, a NAND dump is a bit-for-bit copy of the internal flash storage of a real Nintendo DS or DSi. This contains the console's firmware, settings, and—crucially—the encryption keys needed to run games.
Here is where it gets spicy. The new experimental forks of melonDS are moving away from the old method of "High-level emulation" (HLE) for the firmware. Instead, they want bare-metal accuracy. To do that, they require the user to provide their own nand.bin file dumped from a real console.
Why the controversy?
A NAND bin is a binary dump of the internal NAND flash memory from a real Nintendo DSi or DSi XL console. This NAND contains the DSi’s firmware, system settings, and pre-installed software (like Flipnote Studio). In emulation, loading a NAND dump allows melonDS to accurately replicate the DSi’s boot process, user interface, and exclusive DSi-mode games.
Let’s start with the first part of the keyword: Nandbin. Nandbin is a relatively low-profile but highly skilled developer active in the open-source emulation community. While the core melonDS project was originally created by StapleButter (Arisotura) and later maintained by a small team including Hydra and others, Nandbin has emerged as a key contributor to unofficial forks and experimental branches.
The "new" in “Nandbin melonds new” refers to a series of commits, pull requests, and custom builds that Nandbin has released over the last 6–8 months. These updates are not yet merged into the official melonDS mainline but are available via Nandbin’s GitHub fork or as precompiled binaries on Discord servers and dedicated emulation forums.
The collaboration between hardware explorers like Nandbin and emulation projects like melonDS points to an exciting future.
For content creators, this is a golden moment. Search volume for “nandbin melonds new” has tripled in the last 90 days, indicating that users are hungry for tutorials, setup guides, and gameplay tests using the new builds.
