To run DSi mode, melonDS requires four specific files dumped from a physical DSi console: : ARM7 BIOS (16 KB) bios9.bin : ARM9 BIOS (4 KB) firmware.bin : DSi Firmware
: Nandbin hasn’t officially released a standalone tool — the "Top" layout is typically shared via screenshots or community uploads. Always scan any downloaded config files for safety.
Place these files in a secure directory, ideally a dedicated DSi folder.
To activate DSi mode successfully, melonDS requires a specific set of matching system dumps. These files must be placed within your emulator’s designated system folder: Required Filename Exact File Size Manages the DSi ARM9 primary processor core. dsi_bios7.bin Manages the DSi ARM7 secondary processor core. dsi_firmware.bin nandbin melonds top
MelonDS offers extensive screen customization options that truly make it a "top" emulator in terms of usability:
If the NAND is loading but the top/bottom screens are not arranged properly, adjust the display settings: Go to -> Video .
: Emulates an access point (melonAP) that games can connect to. Direct mode uses libpcap (requires Ethernet connection and administrator privileges) and is more reliable, while indirect mode runs without administrative permissions but may have more compatibility issues. To run DSi mode, melonDS requires four specific
To run DSi-specific software (often called DSiWare) on an emulator like melonDS , users must provide specific system files that the emulator cannot legally distribute. The file is the most critical of these; it is a raw backup of the physical console’s internal NAND flash memory. This file contains the console's operating system, unique encryption keys, and any installed digital games. Without it, the emulator has no "brain" to process DSi-exclusive tasks. The Role of melonDS
Now that your emulator is set to "top tier," here are the absolute best games to test your configuration. These titles run flawlessly on melonDS when configured with the right NAND and settings.
Do not ask for direct download links. You must dump these files from your own hardware using tools like nds_biostool or GodMode9 on a hacked 3DS/DSi. Distributing copyrighted BIOS files is illegal. To activate DSi mode successfully, melonDS requires a
The nand.bin provides the authentic Nintendo DSi Menu experience, allowing you to launch games just as you would on original hardware.
Search for "Nandbin Melonds Top" on YouTube and you will find video tutorials confirming these exact steps—because the community standard is clear: good BIOS files make great emulation.
This comprehensive guide will walk you through every level of melonDS , from the most crucial BIOS and NAND configurations to the "top tier" performance hacks that will transform your gaming experience.
Yes. Unlike DS games, DSi games and DSiWare require the full DSi system environment, which includes the NAND image. Without it, melonDS cannot boot DSi-mode at all.
