Citra is a Nintendo 3DS emulator. It's totally free, multi platform and open source, created by a group of programmers called Citra Team. It may emulate sound completely, something that RYUJINX
can not do. Multiplayer through networked WiFi is supported, which permits you to play multiplayer games with other people, even though they must be utilizing Citra. You can't play multiplayer with people which are using an actual Nintendo 3DS.
Setup of Citra works with Windows, MacOS, Linux, and Android, though the Android version is in early access as of now. The overall consensus is that Citra installation is very easy, quick, and rather simple, with a great deal of guides and tutorials offered for you. While picking Citra, you can choose between two variants, both of which have advantages and disadvantages to utilize. The more steady variation is Citra Nightly, that's the much more secure variant of Citra. The second version, called Citra Canary, includes new features, modifications, and upgrades that Nightly does not have. These attributes are occasionally experimental and may or may not end up in the Nightly version, but they're often features that can not be used with better performance, or characteristics that cause the game to lag or work improperly throughout gameplay.
You need Windows 7, 8, or 10 to play either Citra variation on Windows. To play on MacOS, you'll require version 10.13 High Sierra or even higher. To perform on Linux, you will need a 64-bit contemporary edition, and Windows 8 is required to run Citra on any and all of Android devices. Officially, all hardware must be at least 64-bit to operate Citra's applications. To play games, you'll need both a Nintendo 3DS and a game controller. Citra has a large assortment of games that you can playwith, but you must have the game cartridge of each game you need to playwith. This can make gameplay quite inconvenient.
