melonDS vs Panda3DS

melonDS is a free, open-source emulator focused on Nintendo DS emulation, with builds listed for Windows, macOS, and Linux. Its feature list includes a nearly complete CPU, video, and audio core, a JIT recompiler, an OpenGL renderer with 3D upscaling, joystick support, savestates, RTC, microphone, and lid controls. The project also lists DLDI support. Wi-Fi features include local multiplayer and online connectivity, but are a work in progress and may not work with all games. DSi emulation and GBA slot add-ons are also in progress. DS emulation requires configured BIOS and firmware files; DSi emulation additionally needs a DSi NAND image. melonDS uses raw save files and can import saves from DeSmuME, DraStic, or a flashcard, but does not support the special save memory type used by WarioWare DIY and Jam with the Band. Direct online connectivity requires libpcap or WinPcap, Ethernet, and administrator or superuser privileges; indirect mode does not require Ethernet or those privileges. The software renderer is more accurate but more CPU intensive, while OpenGL may be faster but less accurate.

Panda3DS is a free, open-source emulator for Nintendo 3DS games on computers and portable devices. It supports Windows, macOS, Linux, and Android, with Lua scripting, cheats, controller input, support for some system apps, and work-in-progress amiibo support. The project offers automatically updated nightly builds and manually updated stable builds released every few weeks. Desktop builds include an SDL frontend without a GUI and an experimental Qt frontend with a user interface. Panda3DS is still in early development: many games boot, while many do not, and graphics, audio, and usability features can be incomplete. Compatibility information may not always be up to date, and not all games have been tested. Android is also early in development, so compatibility and performance may differ from desktop. Audio support is experimental; the configuration menu is still being developed, and settings must be changed by editing config.toml in a text editor. The emulator is licensed under GPLv3.
