Are you asking me? I don’t deal with development of the recreation of servers nor handle fan wifi servers
Also Skylink replied you (above) relating to this: there was a flaw in the NDS server that people could *eventually* utilise to host their own servers. It isn’t the entire process, but it allowed fan servers to be used on vanilla unhacked devices.
Since this flaw isn’t on the 3DS, even if fan servers for Pokémon pop-up, it’ll only worked for non-vanilla modified devices. (Read my original quote, that the qualifying statement I used was *vanilla 3DSs* )
