Moded 3ds using citra multiplayer

Put it simple i want to play with a friend a modded version of ultra sun where it is multiplayer but he is using citra and the rom won’t work on my citra so i used my jailbroken 3ds but i can’t connect to citra severs, are there any files that will allow me to do this?

This isn’t possible. In case you wish to troubleshoot your ROM in Citra, please open up a Citra support topic with the relevant information.
