==Shared data==
+
==System Requirements==
−
Some 3DS games make use of shared files from the console's system software. These games will not boot in Citra if said files are not present in the user folder.
+
Operating system: Windows 7+ 64-bit, macOS 64-bit or Linux 64-bit
−
 
 
−
These files are not provided by the Citra developers for legal reasons, so they can be downloaded from the [[Emulator Files#Nintendo 3DS|Emulator Files]] page.
 
−
 
 
−
==Importing saves==
 
−
Some games require this to bypass bugs in title screens.
 
−
# Get the Title ID for the game version you have from [http://www.3dsdb.com/ here]. For example, we'll try with the European version of Zelda: ALBW. Its full Title ID is <code>00040000000EC400</code>.
 
−
# Take the last 8 digits of the Title ID. (in our example, <code>000EC400</code>) In case this method fails later, take <code>00000000</code> instead, or make sure the save file and the ROM image are from the same region.
 
−
# Make an empty folder named as that partial Title ID (<code>000EC400</code>). Put inside it another folder named "data", then inside that one put another folder named <code>00000001</code>, then inside that one put the actual save data files.
 
−
# Move the folder with the title ID and put it here:
 
−
#: <code>\user\sdmc\Nintendo 3DS\00000000000000000000000000000000\00000000000000000000000000000000\title\00040000</code>

==Issues==
+
Processor: x86_64 compatible with AVX2 or SSE2 support
−
===Emulation issues===
 
−
Emulation for various features is non-existent or not actively worked on enough to be in a usable state. This includes:
 
−
* Connectivity features relying on Wi-Fi (Wii U/3DS, Switch/3DS, 3DS Local Multiplayer, 3DS Online...), not in small part due to the setbacks hindering Wi-Fi DS emulation. However, Download Play is emulated.
 
−
* New 3DS mode. It is now in a playable state, but some games may still crash with it enabled.
 
  
−
===Game image format===
+
Memory: 512 MB RAM
−
Citra accepts games in '''.3ds, .cia or .cxi format'''. Furthermore, in Summer 2017, chances are your existing dumps tailor-made for Citra most probably made with the officially recommended tool braindump, which were missing some data yet could be emulated on Citra, have had their compatibility broken as a design choice with no options provided to fix those dumps. You'll have to get new dumps.
 
  
−
Furthermore, while the latest sighax exploit allows for dumping decryption keys to convert (and possibly load) encrypted games in either .3ds or .cia format, development for a solution to allow for this Citra, even one requiring keys from your console, isn't actively pursued ''as a design choice''. Tools on 3DS and PC exist to convert those to decrypted .3ds format for the time being, and a guide can be found [[Nintendo 3DS emulators#Encryption|here]].
+
Graphics: OpenGL 3.1 support (Order-independent transparency support is only available in OGL 4.3 or higher)
  
−
===Telemetry===
+
Android: Android 5.0+, OpenGL ES 3.1
−
Citra developers decided to implement a telemetry feature uploading to them through Internet connection detailed logs and data about your computer specs and the games you're playing. When booting Citra for the first time, you get asked if you want to enable it.

On [https://redream.io/posts/improving-audio-video-synchronization-multi-sync July 2018], inolen introduced a major change to redream's audio/video synchronization in version 1.2.3 by utilizing a feature called, in his words, "MultiSync". This helps to prevent audible crackling, unexpected latency in audio and skipped or torn frames in video output. The solution does involve some added code complexity and memory bandwidth to handle the extra bits.

It is, therefore, possible to use a [https://play.google.com/store/apps/details?id=com.microsoft.rdc.android.beta remote desktop client] via your phone, to emulate with Citra and stream from your PC to your phone.

"It also has a few more subtle benefits:
 +
*Lower spec machines have more time to do actual emulation work as the main thread is never blocked by [[vsync]].
 +
*If the user has vsync force disabled in their control panel, emulation still runs at the correct speed since it's being driven by the audio sync."
  
−
On May 23, 2020, an [https://citra-emu.org/entry/announcing-citra-android/ official Android release] for Citra came out. The minimum requirements are Android 8 (64-bit) and OpenGL ES 3.2 support. Many games achieve playable framerates on a variety of hardware, though the developers recommend an Android device with a Snapdragon 835 chip or better.

redream is a closed-source Sega Dreamcast emulator. It was formerly licensed under GPLv3, but then went closed-source in January 2018.[1] There are two editions of redream: Lite and Premium. Lite is free to everyone while Premium is payware but added high-definition rendering compared to Lite. The emulator is one of the few if not the only Dreamcast emulator that can run without a BIOS; however, using a BIOS is highly recommended as some games may have bugs as the replacement BIOS is not currently perfect.

Overview

On July 2018, inolen introduced a major change to redream's audio/video synchronization in version 1.2.3 by utilizing a feature called, in his words, "MultiSync". This helps to prevent audible crackling, unexpected latency in audio and skipped or torn frames in video output. The solution does involve some added code complexity and memory bandwidth to handle the extra bits.

"It also has a few more subtle benefits:

  • Lower spec machines have more time to do actual emulation work as the main thread is never blocked by vsync.
  • If the user has vsync force disabled in their control panel, emulation still runs at the correct speed since it's being driven by the audio sync."
