melonDS

by Arisotura

Nintendo DS and DSi emulator

melonDS aims at providing fast and accurate Nintendo DS emulation. While it is still a work in progress, it has a pretty solid set of features.

Nearly complete core (CPU, video, audio, ...)
OpenGL renderer, 3D upscaling
RTC, microphone, lid close/open
Joystick support
Savestates
Various display position/sizing/rotations modes
Work-in-progress Wi-Fi emulation for online connectivity and local multiplayer
Experimental emulation of the Nintendo DSi
...and even more is planned!

Note: BIOS and firmware files dumped from a real DS or DSi console are required to use melonDS.
