Replacements
Listings that take over the same core job as melonDS.
DeSmuME
Long-running Nintendo DS emulator with high-resolution rendering.
DeSmuME is an older Nintendo DS emulator with high-resolution 3D rendering, a large cheat database and movie recording, but releases are infrequent and it is slower and less accurate for many games.
RetroArch
One front end for dozens of emulators, with unified settings, shaders and a controller setup you only do once.
RetroArch runs emulator cores inside one front end with shared settings, shaders and controller setup on desktops and phones, though standalone emulators are sometimes more accurate than the equivalent core.
NooDS
A fast, portable open-source emulator for the Nintendo DS and Game Boy Advance.
NooDS emulates DS and GBA with multi-core software rendering and adds an Android build, but has a smaller feature set, no local wireless mentioned and a single main developer.
SkyEmu
A low-level emulator for the Game Boy, Game Boy Color, Game Boy Advance and Nintendo DS.
SkyEmu covers DS alongside Game Boy, Game Boy Color and GBA with low-level emulation, but lists only macOS and Linux and its platform support is not clearly documented.
Also worth comparing
These listings name melonDS as their own alternative, so the relationship runs both ways.
no$gba
A Game Boy Advance, Nintendo DS and DSi emulator with a source-level debugger.
melonDS is an open-source GPL-3.0 DS and DSi emulator for Windows, macOS, Linux and FreeBSD with local wireless play, but it lacks no$gba's source-level debugger and GBA support.
