Why can't emulators emulate local wireless?

    I'm curious why emulating local wireless for DS games and 3DS games is still impossible. Is it a spec thing or visibility thing?

    The DS uses special hardware that cannot be replicated on emulators.
    Not only that, but Desmume hasn’t been updated in a while and NoCash doesn’t focus on emulating this, so unless someone rolls around and makes another emulator with this function in mind, maybe it’s possible, but I doubt it will.

    In addition to that the protocol used by DS connectivity, aka "Ni-Fi", is a propietary variation of the 802.11 standard and requires modded drivers to make it work, which so far have been made only for very few and very old chipsets.

    I don't know if emulating such a functionality over the internet via encapsulation would require custom drivers (and imho it wouldn't make much sense as you can already connect to the internet via DesMuMe) but it definitely would for emulator to physical DS/3DS/Wii local play.

    MelonDS has local wireless though, it's a new emulator and the local wireless is in beta right now, most games work with it.

    You do have a work round hacking the Nintendo Wi-Fi USB Connector and tricking the DS into thinking is online play.

    Or you could connect the DS and the emulator to a custom server.

    Not sure what proprietary hardware or custom drivers have to do with it if you're just wanting 2 instances of the emulator to talk to each other (the same way link cable emulation works in the older Game Boy and gba emulators). Those would only be relevant if you want to communicate with a real DS.
