Nintendo 3DS emulator za Android?

Citra for Android is still unofficial
So, first things first, this is still an unofficial port. It's not officially endorsed by the developers of Citra, and until recently, was actually plagued with ethical concerns over its violation of the GPL. That has been rectified since its published source code to GitHub, but it's something to keep in mind as well to the legitimacy of it all. It works, but if you'd rather wait for an official release from the Citra developers (which has apparently been in the works for a long time now) then you can wait for that. If you want to start using it now though, it's extremely simple to use and navigate. There are a lot more features than that older port allowed as well, including actually useful features such as internal resolution scaling, emulation regions, and more. You can check out the screenshots below to see all of that.
