DeSmuME (formerly known as YopYop DS) is a Free/Open source Nintendo DS emulator for Linux, Mac OS, Wii, AmigaOS 4, and Windows. Its name is derived from emu (which is short for emulator), DS and ME.


The original DeSmuME[edit]

The original emulator itself was in French (with user translations to English and other languages). It supported many homebrew Nintendo DS ROM demos, as well as a handful of Wireless Multiboot demo ROMs.

YopYop156 stopped development on DeSmuME at version 0.3.3 due to a change of laws regarding emulation in France, which was later discovered to be an April Fool's joke. After receiving feedback he eventually decided to quit anyway, and the source code was released.

DeSmuME Team[edit]

Several developers initially released unofficial builds of DeSmuME based on YopYop original code. These various developers later united and merged their work, resulting in version 0.5.0 as their first release.


DeSmuME supports save states, Dynamic recompilation (JIT), V-sync, the ability to increase the size of the screen, filters to improve image quality and has software (Softrasterizer) and OpenGL rendering. DeSmuME also supports microphone use on Windows and Linux ports, as well as direct video and audio recording. The emulator also features a built-in movie recorder.

On April 18, 2010, it was then reported by one of the contributors that work on Wi-Fi has reached a milestone. It has been confirmed Mario Kart DS is possible to link and Worms: Open Warfare 2 can use Wi-Fi to play, albeit limited, multiplayer for 1 round. As of June 18, 2010, Wi-Fi was removed from the emulator by the developers due to actions by Nintendo[citation needed]. A developer reported that the Wi-Fi feature would remain disabled until they could get it "perfect enough to not get noticed again at Nintendo's side".[citation needed]

With the discontinuation of Nintendo's support for online play of DS games, the issue has been rendered moot.

Graphical improvements[edit]

  • DeSmuME supports the following image scaling filters: LQ2x, LQ2xS, HQ2x, HQ2xS, HQ3x, HQ3xS, HQ4x, HQ4xS, 2xSaI, Super2xSaI, SuperEagle, EPX, EPX+, EPX1.5X, EPX+1.5X, Nearest1.5X, Nearest+1.5X, Nearest2X, Scanline, Bilinear, 2xBRZ, 3xBRZ, 4xBRZ, 5xBRZ.
  • The OS X version of DeSmuME also has support for multi-pass post-processing shaders and filters since v0.9.11, as well as high-resolution 3D rendering since SVN r5245. The Windows and Linux versions currently don't have these features.

System requirements[edit]

According to the official wiki project, there are no real minimum hardware requirements for DeSmuME, but most games will run fairly well on the following hardware:[5]

  • Windows OS: Windows XP SP2 or later
  • Mac OS: OS X v10.5.8 Leopard or later
  • Linux OS: Any recent Linux distribution with a 2.6 kernel
  • CPU: 2.0 GHz Intel Core 2 Duo or equivalent
  • RAM: 1 GB

Unofficial ports[edit]

It has also been ported to other systems, including a proof of concept port to the PlayStation Portable. That port has been called "useless" because the PSP does not have a touchscreen, and lacks the processing power to emulate games at full speed.[6] Despite these shortcomings, it does show that successfully running Nintendo DS software on a PSP is possible.[7] There is also a RetroArch/Libretro port.[8]

DeSmuME X432R[edit]

DeSmuME X423R[9] is a fork that includes some additional features for the Windows port. It is best known for adding an experimental high-resolution 3D renderer long before mainline DeSmuME received the same feature.
