So far, the only emulator to actually made any progress is melonDS, but even that is still under development.  ===Local Wireless Communication===Players who have a copy of the same game can link together using the DS's wireless signals, given that the game offers this feature.

*'''===DS Download Play''' (Single cartridge) - ===Players who both have a DS's but only one copy of a game can use the "Download Play" button on the start menu to play together with one player using the actually game, while the other plays using a "downloaded" version of it. Normally they are simple mini-games or stripped down versions of the main game, but some games like ''Mario Party DS'' requires Download Play in order to use its multiplayer. This was also used by some retailers in which a kiosk would contained several DS's with systems containing a special cartridges that would use offer demos via Download Play to offer downloadable demos.

*'''===Nintendo Wi-Fi Connection''' (Online multiplayer) - === Nintendo's online service that was available for the Wii and DS and was free to use. It was shutdown on May 20, 2014 due to the company GameSpy, which was who were the company that was ones managing these servers, shutdown its multiplayer services after being bought out. A popular game that used this feature was ''Mario Kart DS''.

*'''===DS/Wii Connectivity''' - It uses ===Uses the DS's wireless communication on the DS to connect to the Wii. Only The idea is parallel to the GBA Link Cable for the GameCube, and just like the Link Cable, only a handful of games actually have this feature. Some notable examples are ''Pokemon Battle Revolution'' in which players could transfer their Pokemon to the game and use the DS as a controller, ''Animal Crossing: City Folk'' in which data could be transferred between the DS version ''Animal Crossing: Wild World'', and the ''Nintendo Channel'' on the Wii where players could download demos of DS games to their console using Download Play. So far, no emulator has been able to emulate this feature, nor have attempted to, and considering that the GBA/GCN connectivity on Dolphin has yet to fully functions, hints that this feature won't be emulated for a while. 

These features are not supported by So far, no emulator has been able to emulate this feature, nor have attempted to, and considering that the mainline DeSmuME project in particular due GBA/GCN connectivity on Dolphin has yet to timing inaccuracies and ''creative differences''fully functions, and ithints that this feature won's highly unlikely they will ever t be included in the futureemulated for a while. If you're interested in these featuresthis was ever going to be emulated, follow other projects and refrain from contacting the developers about them as per their wishes in their "official stance" it would require work on Wi-Fi features in generalboth parties.
