melonDS is a work-in-progress Nintendo DS emulator aiming for better performance than DeSmuME and to emulate Wi-Fi and local multiplayer capabilities. It's developed by StapleButter, a former contributor to DeSmuME, and has been available as a libretro core since version 1.6.



The sole developer put the melonDS project on a hiatus on May 2018. He left this to-do list for anyone who would wish to contribute to improving that emulator, which is still open-source. On July 2018 he announced that he was going to keep developing the emulator.

Getting Started

From the README on GitHub:

melonDS requires BIOS/firmware copies from a DS. Files required:
  • bios7.bin, 16KB: ARM7 BIOS
  • bios9.bin, 4KB: ARM9 BIOS
  • firmware.bin, 128/256/512KB: firmware
Firmware boot requires a firmware dump from an original DS or DS Lite. DS firmwares dumped from a DSi or 3DS aren't bootable and only contain configuration data, thus they are only suitable when booting games directly.
DS BIOS dumps from a 3DS can be used with no compatibility issues. DSi BIOS dumps should be usable too, provided they were dumped properly.
