This is the Controller setup guide for the Nintendo 3DS Emulator Citra! You need to be using the OFFICIAL BUILDS of Citra, I cannot say that this way will be compatible with the hacked versions as they are not stable. In the Version I am showing you using the most advanced version… THE BLEEDING EDGE BUILDS!
This is the best way you can run all the titles from the Official Nintendo 3DS!
*Remember, this like many other Emulators is WIP. That means that not EVERY game is fully playable yet, but it is now getting very good at it! Always ensure that you pay for what you play and support all developers!*
