There are three legitimate methods to obtain a nand.bin file.

Nandbin Melonds is not merely a keyword—it is the gateway to the definitive Nintendo DS emulation experience on mobile. While the extra setup step of sourcing a NAND binary deters casual users, the reward is unparalleled accuracy, faster performance, and access to the elusive DSi library.

If you own a DSi and are willing to dump your own firmware, Melonds with a proper Nandbin transforms your Android phone into the ultimate DS retro handheld—no stylus required, but highly recommended.


Have you successfully set up Nandbin Melonds on your device? Share your experience in the comments below, and don’t forget to back up your original NAND file before experimenting!

I'd like to introduce you to "Nandbin Melonds," a term that seems to be a combination of "NandBin" and "Melons." While it might not be a widely recognized term, I'll create a write-up that could make it useful and informative.

Nandbin Melonds: A Concept for Sustainable Food Systems

In the pursuit of innovative solutions for sustainable food systems, the concept of "Nandbin Melonds" emerges as a hypothetical model that combines elements of permaculture, urban agriculture, and community-driven food production. This model envisions a future where local food systems are not only sustainable but also equitable and resilient.

The fork is not on GitHub (due to DMCA concerns? No, mainly because the developer uses GitLab). Current sources:

Configuration tips:

| Device | Mainline MelonDS (0.9.3) | Nandbin MelonDS (Dec 2023) | Notable Gains | |-------------------------|--------------------------|----------------------------|----------------| | Raspberry Pi 4 (4GB) | 35-45 FPS (Mario 64 DS) | 58-60 FPS | Playable now | | Anbernic RG552 (ARM64) | 25-40 FPS (Pokémon B/W) | 55-60 FPS | Double speed | | Intel Celeron N4120 | 30 FPS (Metroid Prime H) | 52 FPS | 70% faster | | Steam Deck (x86_64) | 60 FPS (locked) | 90 FPS (uncapped) | Overkill |

Note: These gains are only for 3D-heavy games. 2D games (e.g., Castlevania: Dawn of Sorrow) show minimal improvement and often introduce graphical glitches.

As of late 2024, the developer of Melonds has been working on SDL2 frontend updates and more precise NAND timings. The community expects full DSi-mode camera rotation and microphone noise filtering in upcoming builds. For retro handheld enthusiasts, keeping an eye on the official GitHub and Reddit communities (r/EmulationOnAndroid) is critical for new Nandbin-related patches.

The standard Nintendo DS ran at 67 MHz. The DSi (and by extension, DSi mode in Melonds) runs at 133 MHz—double the speed. With the Nandbin Melonds setup, certain sluggish games (like GTA: Chinatown Wars or Pokémon Black/White 2) receive a noticeable performance boost.

Developers of melonDS sometimes use a blank, formatted DSi NAND from open-source tools like dummydsi (part of melonDS’s source repo). These lack Nintendo’s copyrighted content (like system titles). They allow booting to a minimal menu but cannot run commercial DSiWare. For most users, this is not useful.
