'''melonDS''' is a free and open-source [[Nintendo DS emulators|Nintendo DS emulator]] aiming for better performance than [[DeSmuME]] and to emulate Wi-Fi and local multiplayer capabilities. It is developed by Arisotura (formerly known as StapleButter), a former contributor to DeSmuME, and has been available as a [[libretro]] core since version 0.6.

There is very little to tweak in terms of improving performance (which can be a good or bad thing). This is mainly due to the developer's goal of accurate emulation rather than providing game-specific hacks.

The OpenGL renderer is still being worked on, meaning that there is a small chance some models/textures may not render correctly.

On October 15, 2019, Arisotura released [http://melonds.kuribo64.net/comments.php?id=103 the beta version of an emulator called melonDSi], an experimental melonDS branch for DSi emulation. It used to require a lot of files to be dumped to work (most of which were console-unique), but it has been reworked to require less files (namely, the DSi ARM7 and ARM9 BIOS, the DSi Firmware and a NAND dump). It has since been merged into the master branch and is available on melonDS 0.9.

On October 15, 2019, Arisotura released [http://melonds.kuribo64.net/comments.php?id=103 the beta version of an emulator called melonDSi], an experimental melonDS branch for DSi emulation. So far, it's able to boot into the home screen of the DSi's firmware and boot some DSiWare, DSi-Enhanced games and other features (cameras, DSP, new wifi, etc.) aren't supported yet.  It used to have required a lot of files to be dumped in order to work (most of which were console-unique), however it has been reworked to require less files (namely, the DSi ARM7 & ARM9 BIOS, the DSi Firmware, and a NAND dump). It has since been merged into the master branch and is available on melonDS 0.9.

:''Firmware boot (not direct boot) requires a BIOS/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.''

:*''bios7.bin, 16KB: ARM7 BIOS''

:''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.''
:''As for the rest, the interface should be pretty straightforward. If you have a question, don't hesitate to ask, though!''

==System requirements==
 
MelonDS runs on everything with the software renderer, although you jokingly need to follow those "mininum requirements" to run properly:
 
<blockquote>
 
*CPU: Intel Pentium II / AMD Athlon X2, 12GHz
 
*GPU: nVidia GeForce 2 / AMD Radeon HD3500 / ZARG X152 / Voodoo 2
 
*RAM: 12.6TB
 
*HDD: 6KB
 
*5"5 floppy drive
 
*OS: Windows 3.1 or XP / Linux / haiku / 9os / AcmlmOS
 
*PCI-Express or USB 4.1 bus
 
*Network: SSLv3
 
*Keyboard, mouse, cat
 
*Sacrifice goat to Thargos while Jupiter and Pluto are aligned with the Earth
 
(more seriously, though, just try it out and see how well it runs; if it's too slow, remember there are other emulators you can try)
