The DS offers four types of wireless communications:* MelonDS '''Local Wireless Communication''' (Multiple cartridges) - 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.  melonDS supports wireless communication with several games, including ''New Super Mario Bros. '' and ''Pokemon'', but you need to have multiple instances opened which can slow down performance. No$GBA can emulate it but the connection fails somewhere during establishing the actual connection (despite the names from the other DS showing just fine). * '''DS Download Play''' (Single cartridge) - Players who both have 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 a special cartridges would use Download Play to offer downloadable demos.  Download Play isn't supported by any emulator so far, though NDS-bootstrap homebrew on the Nintendo 3DS can boot some of them. MelonDS fails during the download process though some actually go as far as booting, but never to the actual "game"<small>[Citation Needed]</small>. * '''Nintendo WFC Wi-Fi Connection''' (Online Multiplayermultiplayer) - 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 the company that was managing these servers, shutdown its multiplayer services after being bought out. A popular game that used this feature was successfully emulated with ''Mario Kart DS''.  There was a third-party DeSmuME forks that successfully emulated WFC but has quite a bit of requirement (Ethernet cable, though this can be circumvented with external software). After service shutdown, there was a version compatible with the fan servers (restoring all DLC data but sadly most multiplayer games had their content lost forever). melonDS is one of the only emulators to offer wi-fi capabilities. <!--can melonDS connect to any fan servers?--> It's still a work-in-progress, but it works relatively well. * '''DS/Wii connection isnConnectivity''' - It uses the DS't emulated in any capacitys wireless communication to connect to the Wii. Only a handful of games actually have this feature. Some notable examples are ''Pokémon Pokemon Battle Revolution'' playability is very limited 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 wayfeature won't be emulated for a while.
