DeSmuME
Accuracy
Performance
Features
DeSmuME is an open-source Nintendo DS emulator and is among the most accurate. It sports tools designed for hackers, speedrunners, youtubers, and casual gamers (use Dev-builds). Homebrew programs are supported and can even be debugged through GDB. It can be run from the command line directly or as a graphical program and it even allows for increasing internal resolution. It is also available as a libretro core for RetroArch.
DeSmuME X432r is a modified version that has filters, OpenGL video setting, 3D emulation, rotate screen, up scale resultions and much more but requires a higher end PC and hasnt't been updated since 2015.

Most Recent Changes
--0.9.13--
We have added support for high-resolution 3D rendering. Try the new "GPU Scaling Factor" feature to
increase the 3D resolution beyond the native resolution of 256x192 pixels.Also, the Cocoa frontend sees continued
radical enhancements and while the Windows frontend sees some new incremental enhancements.
--0.9.9a--
It's a maintenance and hacks release of a very old branch.
Add the ability to embed microphone sample files into movies.
Movie format has changed, although the emulation core is the same, so movie sync is not affected.
To embed a sample into the movie, go to Config - Microphone Settings, check Use Microphone Sample, select a wav file, and then start recording a new movie.
To embed a series of samples, use the same base name for all of them, and to each of them add incrementing index starting with 0 and separated with an underscore, up to 255 sample files total. Example:
sample_0.wav...sample_254.wav. Alternatively, just name the files after digital indexes. Example:0.wav...254.wav. Then select the 0th file in the series in the Microphone Settings, and all the other files will be loaded automatically.To select the needed sample, use the hotkeys for Mic Next Sample and Mic Prev Sample.
Index of the currently selected sample is recorded at the corresponding movie frames.

0.8 -> 0.9
There have been so many changes that this list can hardly be considered complete.
For this release, we have formatted the list into a high level overview of big changes and bad bugs relative to the previous release. Hopefully what you're interested in.
This list does not include items which are solely performance boosts, for let us just say that virtually every system has been speeded up.
* The savestate system is totally changed and incompatible with old savestates.
* The 3d system should be considered rewritten.
General/Core:
enh: Convert to c++
enh: Add functions for a lid open/close. Holding key (default "Backspace" in Windows port) while game is freeze/non freeze. [CrazyMax]
enh: Add secure area decryption from ndstool [zeromus]
enh: Change savestate code to support loosely bound chunks and more easily other parts of the emu (GE, GPU).
The savestate format is changed, but from now on it is in principle more resilient
(though it will continue to break as we tinker with the internals) [zeromus]
enh: Added SSE2 optimizations for matrices. Since we now make an SSE2 build, more optimizations can be made. [CrazyMax]
enh: Add a preliminary GUI hud system [CrazyMax,zeromus]
CPU/MMU:
bug: Many fixes in IPC and GE FIFOs. Fixes freezes in NSMB, dsracing, and others. [CrazyMax,luigi__,shash]

enh: Add cosine interpolation in the SPU (conditionally compiled) [zeromus,luigi__]
enh: Experimental: always one silent non-mixing SPU core at 44.1khz synched with emu, for more precision.
The audible core runs with the host, causing music to slow down but not tear or pitch bend. [zeromus]
Graphics:
- Overhaul 3d:
. Move entire GE to core emu.
. Move OpenGL renderer to emu core for optional use by platforms, removing ogl_collector. Now every platform shares the same 3d code.
. Reorganize 3d code to defer rendering to after 3d vblank. Eliminates tearing, and texturing artifacts. [zeromus]
. Add optional fragment shading pipeline (more precision) [luigi__]
. Move lighting model to software instead of using opengl's fixed function model [zeromus]
. Render shadow volumes; toon shading and highlight table [zeromus, luigi__]
. Added texture caching! big speed up. [CrazyMax]

bug: Add 3d layer h-scrolling [zeromus]
bug: Added transparency and fixed material alpha support and alpha testing on the 3D core [shash]
bug: Rewrite VRAM mapping control and rendering (more accurate) [CrazyMax,luigi__]
bug: convert colors to opengl better to prevent alpha=31 polys from being ever so slightly transparent [zeromus]
enh: Add MMU->GPU signal for when vram mappings change to function as a texture cache invalidate signal [zeromus]
enh: Make matrix 4x4 multiply routines use W-coordinate; carry w coord through pipeline [zeromus]
Mac OS X port:
bug: Fixed: Filenames and paths with unicode characters now work. [Jeff]
bug: Fixed: Load state from file button works again. [Jeff]
enh: Save State panel now pauses emulation while the file selection box is open. [Jeff]
