It '''melonDS''' is a free and open-source [[Nintendo DS emulators|Nintendo DS]]/[[Nintendo DSi emulators|DSi emulator]] aiming for better performance than [[DeSmuME]] and to emulate Wi-Fi and local multiplayer capabilities. Its developer is Arisotura (formerly known as StapleButter/Luigi__), a former contributor to DeSmuME, and it is available for download at as a [[libretro]] core since version 0.6. Its first commit on GitHub was on May 15, 2016. ==Downloads=={| cellpadding="4"|-|align=center|{{Icon|Win|Lin|Mac}}|'''[http://melonds.kuribo64.net/downloads.php Official Builds]'''<br/><small>Also available on [https://github.com/Arisotura/melonDS/releases Github]</small>|-|align=center|{{Icon|Win|Lin|Mac}}|'''[https://github.com/Arisotura/melonDS/actions Dev Builds]'''|-|colspan="3"|<hr/>|-|align=center|{{Icon|Android-big}}|'''[https://github.com/rafaelvcaetano/melonDS-android Source]''' '''[https://play.google.com/store/apps/details?id=me.magnum.melonds Play Store]''' <br/> Unofficial melonDS Android port|-|colspan="3"|<hr/>|-|align=center|{{Icon|NX-big}}|'''[https://github.com/RSDuck/melonDS/releases Release 6]<br>[https://gbatemp.net/threads/melonds-for-switch-continuation.570021/ GBATemp Thread]'''<br><small> Ported by Hydr8gon, and currently maintained by Generic (aka RSDuck), who added an ARM64 JIT and other improvements.

The Like most emulators, development has been rocky with at one point the sole developer put putting the melonDS project on a [http://melonds.kuribo64.net/comments.php?id=42 hiatus on in May of 2018]. However he has left leaving this [http://melonds.kuribo64.net/comments.php?id=43 to-do list] for anyone who would wish wished to contribute to improving that the emulator, which is still open-source. [http://melonds.kuribo64.net/comments.php?id=44 On July 2018] it was announced that development was going to continue for melonDS and has since shown potential.  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. ==melonDSi==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.

If you have a question, don't hesitate to ask, though!'' These files can be found [[Emulator_Files#Nintendo_DS_.2F_DSi|here]]. If you do choose to look elsewhere online for system files, be warned that there are old hacked dumps floating around that breaks if the WFC configurations are altered. To use the OpenGL renderer, you must have at least OpenGL 3.1.More information can be found [http://melonds.kuribo64.net/faq.php in this FAQ]. To use melonDS in DSi mode, you need extra files which can be found [[Emulator_Files#Nintendo_DS_.2F_DSi|on this page.]] ==System requirements==MelonDS runs on everything with the software renderer, provided they were dumped 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)</blockquote> ==Gallery==<gallery>Metroid2X.png|Top: 2x the native resolution without OpenGL. <br>Bottom: 2x the native resolution with OpenGL Chibi4x.png|Top: Native software render. <br>Bottom: 4x the native resolution with OpenGL </gallery> <!--==References==<references/>--> ==External links==* [https://emucross.com/the-one-that-flourished/ The One That Flourished: A Look at melonDS 0.8] (By [[Dolphin]] tester [https://dolphin-emu.org/blog/authors/JMC47/ JMC47], aka Justin M.
