[http://melonds.kuribo64.net/comments.php?id=44 On July 2018] it was announced that aimed 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 provide the accuracy developer's goal of higanaccurate emulation rather than providing game-specific hacks. The OpenGL renderer is still being worked on, meaning that there's a slight 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. So far, with it's able to boot into the home screen of the easeDSi'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 offiles to be dumped in order to work (most of which were console-use of bsnesunique), 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. ==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.''

It seeked to accomplish this by catering to the common 99% of use cases, rather than higan, which tries These files can be found [[Emulator_Files#Nintendo_DS_.2F_DSi|here]]. If you do choose to cater to every niche. As such, certain advanced functionality was not available in byuu; howeverlook elsewhere online for system files, be warned that there are old hacked dumps floating around that breaks if the emulator was significantly easier to use, like bsnesWFC configurations are altered.

Unlike bsnes, byuu would also put accuracy at In order to use the forefrontOpenGL renderer, you must have at least at first, to uphold Near's vision for emulator designOpenGL 3.1.More information can be found [http://melonds.kuribo64.net/faq. This means that byuu would have higher system requirements and less enhancements than bsnes, but it will still aimed to offer more features than higanphp in this FAQ].

EssentiallyTo use melonDS in DSi mode, think of it as the bridge between two extremesyou need extra files which can be found [[Emulator_Files#Nintendo_DS_. The goal was to build 2F_DSi|on the success of bsnes, and to offer an easy-to-use interface for all of Near's emulator cores, rather than just for the SNES alonethis page.]]
