Need help from someone who has enabled wifi on desmume

Hi.Since I am unable to establish wifi feature of desmume for some straneg reason and tried for a while, I was wondering if someone who has got it to work might be able to help me with just a small request. Just taking a screenshot in a multiplayer game, it would take 2 seconds. You'll get to play a cool game version as a benefit :)

most versions of desmume do not support wifi, there's only a couple that do and only under a very select configuration. Also the vast majority of online games will no longer work as nintendo have shut down the game servers.

Yeah, I saw that there was a tutorial to set up wifi on a specific version of desmume. But anyway, the wifi for this game is not really to connect to a server, but just to start up 2 player mode. The game needs to detect both players to start up the level, I'm sure this is doable, right? Would really appreciate it if anybody can help out.
