For the uninitiated, Nandbin (also stylized as Nandbin) is a prominent South Korean YouTuber and hardware engineer. His channel is famous for intricate console repairs, motherboard-level soldering, and—most relevant to this topic—reverse-engineering Nintendo’s proprietary hardware.
Unlike typical tech reviewers, Nandbin dives into the raw silicon. He has produced detailed videos analyzing the DS, DSi, and 3DS’s internal architecture, including the NAND memory (hence the “Nand” in his name) and the secondary processors responsible for audio, Wi-Fi, and GBA backwards compatibility.
Despite these advancements, significant challenges remain. Many non-binary individuals still face barriers to accessing affirming and understanding healthcare and mental health services. Discrimination, both within and outside the LGBTQ+ community, continues to be a major source of distress. There is a need for continued advocacy, education, and research to address these issues.
The phrase “nandbin melonds new” is more than just a search query. It represents a paradigm shift in how we preserve and play DS games. Where emulation was once an approximation, it is now becoming a 1:1 reconstruction of the original hardware, thanks to the painstaking work of hardware engineers like Nandbin.
If you haven’t updated your melonDS setup in a while, now is the time. Grab the latest nightly, watch Nandbin’s recent hardware analysis videos, and experience your DS library like never before—with accurate colors, faithful Wi-Fi multiplayer, and DSi mode running smoothly on modern devices.
The new era of DS emulation is here. And it runs on melonDS.

To set up a (nand.bin) in the latest versions of , you primarily need specific system files and a properly configured DSi mode. This guide focuses on the newer "standalone" and RetroArch core setups as of April 2026. 1. Required System Files nandbin melonds new
For DSi emulation, melonDS requires specific files typically dumped from a real console. DSi ARM9 BIOS: dsi_bios9.bin DSi ARM7 BIOS: dsi_bios7.bin DSi Firmware: dsi_firmware.bin
(this is the storage image where DSiWare and system settings are kept). 2. Basic Setup (Standalone melonDS) Placement: Put your system files in a dedicated folder (e.g., C:\melonDS\firmware\ Configuration: Open melonDS and go to Config > Emu settings DSi Settings: Navigate to the Select your DSi ARM9 BIOS DSi ARM7 BIOS DSi firmware files by clicking the browse buttons next to each field. Enable DSi mode Console Type: Change the console type from "DS" to "DSi" in the settings. 3. Managing and Installing Titles to NAND
In newer versions, you can install DSiWare (.nds files) directly to your Stop Emulation: System > Stop
before attempting to edit the NAND; the option will be greyed out if a game is running. Open Manager: System > Manage DSi titles Importing:
Based on community feedback and setup guides, melonDS is widely considered one of the best Nintendo DS and DSi emulators due to its accuracy and the addition of features like DSiWare support. The "nand.bin" file is a critical component for DSi mode; it is a backup of the internal storage from a physical DSi console that allows the emulator to run the DSi home menu and DSiWare titles. Performance and Feature Review
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. Why are these two terms linked
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 For the uninitiated, Nandbin (also stylized as Nandbin)
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
