See below for details about each directory and what data is stored within. Included in this guide are instructions on how to dump various files from a 3DS console to put into the Citra user directory. In general, dumping files from a 3DS will require an SD card reader or some way to use wireless file transfer from a 3DS to a computer and that the 3DS being dumped from has Homebrew Launcher access. If the below articles are too wordy, consult the below tutorials for obtaining optional files to improve the Citra experience:.
This directory contains files containing information that tell Citra how to run. These files are in plain text and thus are fully editable and contain configurations for mapping controls, which [CPU]] and audio engine to use, rendering and other visual options, the [ Log Filters , which region the emulated 3DS belongs to, whether to treat the emulated 3DS as a new 3DS, and whether to insert a virtual SD card into the emulated system.
Changing these files is only to be done by advanced users because making changes at random can cause Citra not to work as expected or at all. The Citra executable has options menus that allow users to change most of the aforementioned configurations safely.
If Citra has trouble running after changing a file and the user cannot remember what they changed, delete the configuration files and run the executable again so that they are regenerated automatically albeit as though Citra is being run for the first time so any existing configurations are lost. This file is automatically generated by Citra and stores the logging. It is overwritten every time Citra is launched. This directory will contain the data directory and potentially also the system archives.
This directory is automatically generated by Citra and contains the system and extra data for the emulated NAND. Inside this directory is another directory, On a physical 3DS, the directory inside data would be named differently.
This knowledge is only important if you plan on dumping any NAND system data or extra data from a physical 3DS and associating it with Citra. Most system save data has a TID high of For details about the different kinds of system save data, see 3dbrew.
For first-time Citra users, there may be nothing inside the sysdata directory. In fact this will be the case for most Citra users, and is nothing to be alarmed about. This data will be created automatically in some cases, such as when a Mii is saved in Mii Maker. Almost none of this data is essential for Citra to run homebrew games or backups of licensed titles. There is one notable exception to the last statement.
Other system save data aside from the config savegame can be dumped from a 3DS console by an expert user and placed in the sysdata folder. At this time, though, many features that read from or write to system save data have not been implemented so there is currently little value in doing so. See this discussion topic for more details about dumping system save data. NAND extra data always has a TID High of , so the extdata directory should contain a folder, though it has been observed in Citra that there may be a folder instead, and users have reported issues if there is both a and folder contained therein, so it is advised to delete the folder if that is the case.
Inside the folder may be nothing, or it may contain one or more directories named F , where can be the characters A-F or the numbers Each of these folders corresponds to a TID low, which can be used to identify the type of extra data stored therein.
See 3dbrew for details about the different kinds of extra data stored in NAND. This folder, named , will only exist if the system archives have been dumped from a physical 3DS. If you require support with the installation or use of Citra, or you want to report bugs you should use this version. This version is still in development, so expect crashes and bugs. The Canary build of Citra is the same as our nightly builds, with additional features that are still waiting on review before making it into the official Citra builds.
We will not provide support for issues found only in this version. Toggle navigation. Download Citra The nightly build of Citra contains already reviewed and tested features. The Citra updater provides a easy interface to install, update and manage Citra. Unless you know what you are doing, this is likely what you are looking for.
