Given the enormous power of today's smartphones, and with the ease of development and modification of all kinds of software projects, it is not surprising that on Android we enjoy a remarkable amount of console emulators. From classic to more current machines, as is the case with the Nintendo 3DS. Want to play your laptop titles? You can do it now.
Citra is a Nintendo 3DS emulator that works on Windows, Mac and Linux computers. Their project is Open Source and they are in continuous development to find an emulation at the height of the original console. And there is a separate and unofficial project, created by weihuoya, that has developed an adaptation of Citra for Android.
