As of June 2020, Ryujinx goes past menus and in-game on over 1,000 commercial titles. Of those, roughly half are considered playable. See the compatiblity list <a href="https://github.com/Ryujinx/Ryujinx-Games-List/issues" target="_blank">here</a>.

## Usage
|
|
|
|
To run this emulator, we recommend that your PC have at least 8GB of RAM; less than this amount can result in unpredictable behavior and may cause crashes or unacceptable performance.
|
|
If you use a pre-built version, you can use the graphical interface to run your games and homebrew: simply add the directory containing your homebrew or games in the Options > Settings > General tab > Game Directories menu item.
|
|
|
|
If you build it yourself you will need to:
|
|
**Step one:** Install the [.NET Core 3.1 (or higher) SDK](https://dotnet.microsoft.com/download/dotnet-core).
|
|
|
|
**Step two (choose one):**
|
|
**(Variant one)**
|
|
|
|
After the installation of the Net Core SDK is done; go ahead and copy the Clone link from GitHub from here (via Clone or Download --> Copy HTTPS Link. You can Git Clone the repo by using Git Bash or Git CMD.
|
|
|
|
**(Variant two):**
|
|
|
|
Download the ZIP Tarball. Then extract it to a directory of your choice.
|
|
|
|
**Step three:**
|
|
|
|
Build the App using a Command prompt in the project directory. You can quickly access it by holding shift in explorer (in the Ryujinx directory) then right clicking, and typing the following command:
|
|
Run `dotnet build -c Release -r win10-x64` inside the Ryujinx project folder to build Ryujinx binaries.
|
|
|
|
Every file related to Ryujinx is stored in the `Ryujinx` folder. This folder is located in the user folder, which can be accessed by clicking `Open Ryujinx Folder` under the File menu in the GUI.
|
|
|
|
## Latest build
|
|
|
|
These builds are compiled automatically for each commit on the master branch. While we strive to ensure optimal stability and performance prior to pushing an update, our automated builds **may be unstable or completely broken.**
|
|
|
|
The latest automatic build for Windows, macOS, and Linux can be found on the [Official Website](https://ryujinx.org/download).
|
|
|
|
## Requirements
|
|
|
|
- **Switch Keys**
|
|
|
|
Everything on the Switch is encrypted, so if you want to run anything other than homebrew, you have to dump encryption keys from your console. To get more information please take a look at our [Keys Documentation](KEYS.md).
|
|
|
|
- **Firmware**
|
|
|
|
You need an official Switch firmware by either dumping directly from your Switch, or dumping your game cartridge to an XCI file; you may install firmware in Ryujinx directly from an XCI file as long as it has not been trimmed. Install the firmware, after you've installed your keys, from the Tools > Install Firmware menu item.
|
|
|
|
- **Executables**
|
|
|
|
Ryujinx is able to run both official games and homebrew.
|
|
|
|
Homebrew is available on many websites, such as the [Switch Appstore](https://www.switchbru.com/appstore/).
|
|
|
|
A hacked Nintendo Switch is needed to dump games, which you can learn how to do [here](https://nh-server.github.io/switch-guide/). Once you have hacked your Nintendo Switch, you will need to dump your own games with [NxDumpTool](https://github.com/DarkMatterCore/nxdumptool/releases) to get an XCI or NSP dump.
|
|
|
|
## Features
|
|
|
|
- **Audio**
|
|
|
|
Audio is partially supported. We use C# wrappers for [OpenAL](https://openal.org/downloads/OpenAL11CoreSDK.zip) (installation needed), the main audio backend, and [libsoundio](http://libsound.io/) as the fallback. Our current Opus implementation is incomplete.
|
|
|
|
- **CPU**
|
|
|
|
The CPU emulator, ARMeilleure, emulates an ARMv8 CPU and currently has support for most 64-bit ARMv8 and some of the ARMv7 (and older) instructions, including partial 32-bit support. It translates the ARM code to a custom IR, performs a few optimizations, and turns that into x86 code. To handle that, we use our own JIT called ARMeilleure, which uses a custom IR and compiles the code to x86.
|
|
Ryujinx also features an optional Profiled Persistent Translation Cache, which essentially caches translated functions so that they do not need to be translated every time the game loads. The net result is a significant reduction in load times (the amount of time between launching a game and arriving at the title screen) for nearly every game. NOTE: this feature is disabled by default and must be enabled in the Options menu > System tab. You must launch the game at least twice to the title screen or beyond before performance improvements are unlocked on the third launch! These improvements are permanent and do not require any extra launches going forward.
|
|
|
|
- **GPU**
|
|
|
|
The GPU emulator emulates the Switch's Maxwell GPU using the OpenGL API (version 4.4 minimum) through a custom build of OpenTK. There are currently two graphics enhancements available to the end user in Ryujinx: resolution scaling and anisotropic filtering. These can both be adjusted in the GUI.
|
|
|
|
- **Input**
|
|
|
|
We currently have support for keyboard, mouse, touch input, JoyCon input support emulated through the keyboard, and most controllers. Controller support varies by operating system, as outlined below.
|
|
Windows: Xinput-compatible controllers are supported natively; other controllers can be supported with the help of Xinput wrappers such as x360ce.
|
|
Linux: most modern controllers are supported.
|
|
In either case, you can set up everything inside the input configuration menu.
|
|
|
|
- **DLC & Modifications**
|
|
|
|
Ryujinx is able to manage add-on content/downloadable content through the GUI. Mods (romfs and exefs) are also supported and the GUI contains a shortcut to open the respective mods folder for a particular game.
|
|
|
|
- **Configuration**
|
|
|
|
The emulator has settings for enabling or disabling some logging, remapping controllers, and more. You can configure all of them through the graphical interface or manually through the config file, `Config.json`, found in the user folder which can be accessed by clicking `Open Ryujinx Folder` under the File menu in the GUI.
|
|
|
|
