This website is the official website for the Citra emulator, an emulator which allows the user to play 3DS games, except they're only playable once decoded, only possible using a real 3DS, effectively preventing acts piracy since the files need a real 3DS... or at least prevent the acts to some degree...
El sitio oficial de Citra, un emulador de 3DS que aún no está terminado, además de permitir descargar el emulador contiene un blog sobre el desarrollo del programa.
