Since melonDS 0.9.4, DSi support has matured, but it still requires users to provide their own DSi BIOS, Firmware, and NAND dump files to ensure compatibility with DSi-exclusive titles and SD card emulation.
With these major updates, how does melonDS compare to the long-standing DeSmuME? The verdict heavily favors the new challenger.

To use a NAND file in melonDS, three specific components are required:
The addition of in newer melonDS releases marks a major step forward for DSi emulation. If you own a DSi and legally dump your own NAND, you can now enjoy near-authentic DSi functionality on PC — complete with the original home menu, settings app, and DSiWare titles.
The work on melonDS is far from over. Even after the blackmagic3 merge, the developers are looking ahead. The next step is reportedly to build a proper . This will open up even more possibilities for graphical enhancements and high-resolution display capture. While the current OpenGL renderer is a "big hack in itself" upscaling a console that was never meant to do so, the new 2D engine aims to be a more elegant and powerful solution. Since melonDS 0
Nandbin’s analysis of the DS’s MAC address handling and wireless protocol (including the little-known unencrypted beacon frames ) allowed melonDS developers to rewrite the Wi-Fi stack.
As we look forward to the official release of , one thing is clear: the emulator is no longer just an alternative; it is the definitive way to experience the Nintendo DS and DSi libraries on modern devices. Whether you are a long-time fan wanting to replay Pokémon HeartGold in stunning high definition or a curious newcomer eager to explore the DSiWare library, the new wave of melonDS has something for everyone. Keep an eye on the official melonDS website and GitHub repository, as the nightly builds are where the magic happens.
you’re an enthusiast with moderate technical comfort and want the best possible performance for 3D or Wi-Fi games. The speed boosts are real, and the UI improvements make daily use more pleasant. | | Audio pitch shift when using Dolby
The goal? Speed. Specifically, running the emulator on lower-end ARM devices (like the Retroid Pocket or Anbernic handhelds) without melting the battery.
In the early days of , only DS Lite/Fat emulation was practical. However, the new melonDS versions, especially in 2026, have introduced robust DSi support, bringing:
The subject refers to the use of (specifically .bin files extracted from a Nintendo DSi system) within the melonDS emulator . The context usually involves a user attempting to set up the emulator for DSi functionality (booting the DSi Menu, running DSiWare, or utilizing DSi-specific features) and encountering issues with file validity, missing keys, or incorrect dumping procedures.
