I am trying to link my 2ds with citra , is there anyway I can do this or not?
In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.
Connection between a 2DS/3DS and Citra is not possible. If this feature is using only local multiplayer features however, you should be able to launch 2 versions of Citra. One a portable Citra version (standalon) and the other the normal installation version of Citra. Then you should be able to link those together.
However, if this feature requires connection to Nintendo’s servers before it can connect, it will not work in Citra.
