0.9.1 / 25-12-2020



MelonDS is a work-in-progress Nintendo DS emulator aiming for better performance while being able to to emulate Wi-Fi and local multiplayer capabilities. It's developed by a former contributor of DeSmuME and even has libretro core available. 

There's also an Android port in development.

It also requires DS BIOS/firmware copies

  • bios7.bin, 16KB: ARM7 BIOS

  • bios9.bin, 4KB: ARM9 BIOS

  • firmware.bin, 128/256/512KB: firmware

Please note 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.





Windows: None Reported

Mac: Install the appropriate libraries beforehand with the Homebrew Package Manager.

         In Terminal, type  "brew install qt5 sdl2 libslirp"
