StapleButter was working on some of these features and left the project due to ''creative differences'' directly related to these features, to eventually start his own Nintendo DS emulator, [[melonDS]]. A DeSmuME fork with online multiplayer, which includes functional code that made it to official version 0.9.7 before being removed due to ''creative differences'', is available and has been improved to allow for limited dumping of online data software prior to the server shutdown in 2014, as well as a version allowing for using online play for a select few games and downloading DLC data from alternative servers with the backed-up data.
Also due to ''creative differences'' it It was also deemed that the Dynamic JIT recompiler (which adds a significant speed-up) to be was a poor fit for the DeSmuME project and as such a fork called "DeSmuME 0.9.9 JIT" including it was made, and some used to recommend it over the mainline project. Much later, like with the internal resolution feature, a compromise on these ''creative differences'' was reached and a slightly different implementation was since included in the main project after 0.9.11.
*In 3D gamesAfter the increased internal resolutions were implemented in the X432 fork, you can use '''DeSmuME X432R''' as linked below or any recent well as in [[DraStic]] and even the barebones official build Nintendo Virtual Console DS emulator on Wii U, the mainline DeSmuME project developers decided to increase the reconsider and include their own implementation for higher internal resolution. It can be surprising how detailed DS textures actually are despite Official dev builds now have the tiny option to render at a higher resolution they were made as well, and filter textures to boot. Overall, it's more hardware intensive than X432R's implementation. The latest development version of [[RetroArch]] DeSmuME core also has an option to increase internal resolution which can be played atset using '''desmume_internal_resolution''' in Core Options.

This is massively CPU-processing effects for 2D games, you have to set it back to native resolutionintensive because only SoftRasterizer exists in RetroArch core.

====Official Implementation====
After the increased internal resolutions were implemented in the X432 fork (originally contributed to main but rejected due to ''creative differences''), as well as in Drastic and even the barebones official Nintendo Virtual Console DS emulator on Wii U, the mainline DeSmuME project developers decided to reconsider their ''creative differences'' and include their own implementation of higher internal resolution.
Official dev builds now have the option to render at a higher resolution as well, and filter textures to boot. Overall, it's more hardware intensive than X432R's implementation.
The latest development version of RetroArch DeSmuME core also has an option to increase internal resolution which can be set using '''desmume_internal_resolution''' in Core Options. This option was added in [https://github.com/libretro/desmume/commit/5e430dfbc22f9d54c77f291304a38352ee1e5a63 August 8, 2015 commit]. This is massively CPU-intensive because only SoftRasterizer exists in RetroArch core.

'''DeSmuME''' is a an open-source [[Nintendo DS emulators|Nintendo DS emulator]]. It is the most accurate Nintendo DS emulator and is actively developedby YopYop156. It can be run from the command line directly or as a graphical program.
The regular version now allows for increasing internal resolution.
==Download==
==Issues==
DeSmuME uses [[Wikipedia:DirectInput|DirectInput]] if an [[Xbox 360 emulators|Xbox 360]] controller is being used. No support for [[Wikipedia:DirectInput#XInput|XInput]] exists. This will be noticeable if an Xbox 360 controller's LT and RT inputs are mapped to emulate the DS's L and R buttons respectively.
Several features aren't supported by DeSmuME and aren't parts of its future as per the emulator's current design philosophy and ''creative differences'', so don't hold your breath for them or pester the developers about them. They include:
*DS Download Play
*DS Local Play (local multiplayer)
*DS Wi-Fi Play (online multiplayer) - ''working, fork-only, removed from main due to creative differences''
*DSi emulation (DSi-enhanced retail, DSi-exclusive retail, DSiWare)
*DS/Wii Connectivity
At some point in 2010, development on these features was permanently discontinued due to ''creative differences'', and the developers distanced themselves from the above-mentioned forksfork. The official team stance on this is as follows, and is as clear as it can get:
::''As you may have come to find, Release versions and WIP builds distributed by DeSmuME developers do not have the WIFI Wi-Fi menu enabled, while builds provided by dodgy scener sites or the one your best friend in the whole wide world has handed to you on a USB key does.''::''Officially, DeSmuME DOES NOT support the use of builds with WIFI Wi-Fi support.''
::''As such, though it may come as a shock to you, requests for help or information about it are thus NOT likely to obtain a response to your satisfaction.''
::''The developers have no current interest for furthering the development of the EXPERIMENTAL_WIFI, and the current state of the DeSmuME source code might have even completely broken it.''
==Troubleshooting==
*If it's still slow, you must be running on a toaster. It can't be helped. But try tinkering with things for the fastest settings you can find.
*Use frameskip as the absolute last resort.
*If you have an your graphics card was designed by Nvidia card and the OpenGL Display Method (useful for its filter) is stuttering despite reporting good framerate, open the Nvidia Control Panel and turn off Threaded Optimization for this program. What's happening is sequential OpenGL code is being put on different processors running at different speeds, forcing them to wait for each other repeatedly.
If the sound is distorted.
*'''Synchronous''' mode is far less buggy. '''Method Z''' seems to work the best in most cases.
==Graphical Enhancement==
*The OpenGL 3.2 renderer option in 3D Settings supports '''Multisampling Anti-Aliasing (MSAA)'''. Turning it on helps the edges of ultra low-res DS polygons and lines smooth out appear to wobble less during movement, and retain their shape better when viewed from distance. Unlike post-processing effects that modify the still frame after completion and essentially try to guess at the shapes they are smoothing, this effect knows the actual shapes of the polygons themselves.
**Versions before r5032 had this option for a long time, but it was only put in the GUI at r5032. To turn it on in older versions you needed to change a value from false to true in the source code and recompile it.
*Recent DeSmuME revisions now add support for texture filtering, greatly reducing pixelation albeit at the cost of blurrier visuals. Some may find this rather jarring or too N64-esque, so it's a matter of individual preference as there's an option to turn it on or off.
===Internal Resolution and DeSmuME X432R=======X432R Fork====Mainline DeSmuME didn't offer any options for higher internal resolution than native, internal resolutions at first, due to ''creative differences''. However, DeSmuME X432R is DeSmuME a fork with the option to increase internal resolution. Be warned that this option is very system-intensive. There have been reports of people who can run [[Dolphin ]] and [[PCSX2 ]] at a perfect pace but can't run this at full speed using increased internal resolution, however newest newer versions are much faster.
While generally more accurate, the SoftRasterizer is massively CPU-intensive in this mode, whereas the OpenGL renderer shares the load with your GPU. This can be considered a '''speedup''' option, but it also boasts an MSAA option unavailable to SoftRasterizer.

==Review==
DeSmuME is currently the best available [[Nintendo DS emulators|Nintendo DS emulator ]] on PCs. It is far better than [[No$|No$GBA]] when it comes to accuracy, though not flawless. However, it's more hardware intensive than any other DS emulator (either NONo$GBA or emulated [[DraStic]]) and many features are not supported.
