The NDS emulators are specifically built for users to emulate Nintendo game on a PC, Windows, Mac, Androids and Linux. Most importantly, NDS emulators are programs that, knowing about the features of a particular console, can translate the computer codes, graphics and sound formats of this console into a system(code) that your PC can understand. In 2004, The Nintendo DS emulators were released by Nintendo family. The only way to send data through Nintendo Ds emulator is via the Download play menu, apart than that it's just some technical data that nobody used. Though, I think there's no program to manage data between the computer and Nintendo DS emulators. This was all done with Pokemon Black and Pokemon White both on Nintendo ds emulators. Although it's nearly not possible to trade using Wifi or more precisely the Friend Codes, some people believe it's possible through a WIRED connection.
