How do you trade with self in desmume emulator?

To trade with yourself in the DeSmuME emulator, you'll need to set up two instances of the emulator. First, open two separate DeSmuME Windows and load the same game ROM in both. Then, use the built-in "Link" feature in DeSmuME by navigating to the "File" menu and selecting "Start Wi-Fi Connection," ensuring both instances are connected to the same local network. After that, initiate a trade from one instance to the other as you would on a real DS.
