The original model and the 2DS had a dual-core ARM11 MPCore at 268 MHz and a single-core ARM9, 128MB of RAM and 6MB of VRAM, and a DMP PICA200 GPU. The New 3DS and New 2DS XL models upgrade this to an 804 MHz quad-core ARM11 and 256MB of RAM, along with an extra pair of shoulder buttons and a right analogue stick.

The most notable feature of this console is the use of [https://en.wikipedia.org/wiki/Autostereoscopy autostereoscopic] (i.e. without glasses) 3D, which can be configured using a slider. This was omitted on the cost-reduced 2DS and New 2DS XL models, which was released due to eye health concerns with children whom Nintendo advised not to use the 3DS's stereoscopic mode (though it is speculated that said advisories were more for liability reasons in case of a health-related lawsuit).

* [[Citra]] is an early in development open-source 3DS emulator made by experienced emulator developers. It is considered experimental, and it runs homebrew applications with a decent degree of compatibility. Though it can play many commercial games to some extent, the emulator has various graphical issues with most games, no sound, and slow speeds. Citra is being regularly worked on, and progress in it is faster than expected for most emulators. However, there's still no telling how long it will be before it is suitable for playing games to completion.

==Game images==
 +
===3DS vs. CIA===
 +
<!--this section is pretty inaccurate-->
 +
There are two big types of 3DS game images currently:
 +
;NCSD-type: Includes '''.CCI''' (CTR Cart Image), aka '''.3DS''' - data on physical carts, can be executed right off the bat, not used much since no one bothered to develop a CFW solution to load them yet (besides converting them to CIA) and only overpriced flashcarts (Gateway/Sky3DS) can load them.
 +
;NCCH-type: Includes '''.CIA''' (CTR Importable Archive) and '''.CXI''' - installers that unpack game data to the SD card or the 3DS NAND memory. Some homebrew apps (FBI, DevMenu) can install CIA files on 3DS systems with CFW installed. Digital games are often distributed as CIAs.
 +
 
 +
*Note that CTR (Citrus) is the internal code names for the 3DS.
 +
 
 +
Due to one format being so far restricted to overpriced flashcarts and the very slow Citra development (meaning playing on a real 3DS is still the preferred way to go), the CIA format is preferred in many sharing websites, downloader tools and even tools to dump your own games.
 +
 
 +
However, converting a CIA image to 3DS format (and vice-versa) is still possible with no loss of content. Read the Encryption section below for a guide.
 +
 
 +
Some outdated dumping utilities intended for use with Citra (like braindump) produce damaged decrypted 3DS images that can't be easily converted back. No known solution exists so far to fix those dumps.
 +
 
 +
===Encryption===
 +
Most dumps online are also encrypted. This encryption poses no problem for playing game images on a real 3DS since it can deal with that encryption with internal keys included in the bootrom, but becomes a problem when trying to emulate them on PC. '''Citra cannot play encrypted games, only decrypted games will work.''' A solution to load encrypted images is for the moment on the back burner and there's not much developer interest for it. If you want to play games on Citra, you'll have to convert your game images to that format.
 +
 
 +
Formerly, decrypting those ROMs used to require real 3DS hardware (bafflingly enough, Citra devs still ask users to do this even nowadays). It required files generated by a real 3DS called '''xorpads''' unique to that game version, using the encryption engine within the 3DS. After this part, these xorpads (which are big) can be used with PC tools (or other 3DS-based homebrew) to produce the decrypted game image. After that, some 3DS homebrew (Decrypt9, GodMode9) included tools to directly convert encrypted images to decrypted images with a single button press, but those still require a real 3DS.
 +
 
 +
But now this new feature was added to citra enables the user to play encrypted games without decrypting them. Read this page
 +
[https://citra-emu.org/wiki/aes-keys/]
 +
 
 +
Then, go to this reddit page and copy the code from second comment (credit floppydoppy2)
 +
[https://www.reddit.com/r/CemuPiracy/comments/gpo2ey/aes_key_nintendo_3ds_title_keys_for_citra/] copy it ,make a new .TXT file names 'aes_keys.txt'
 +
Then you might have that user folder for citra, then open it go to sysdata , assuming that you have a shared font.bin file there paste this AES keys.txt there.
 +
Now user folder is what is the system archive of 3ds you need it to display video
 +
Now put user folder in folder of citra or in  c: drive (see some YouTube videos , read some reddit posts you will understand it)
 +
For user folder:-  [http://www.mediafire.com/file/brdbqzng4iuvvcz/Citra_60_FPS_100%2525_gurantee.exe/file]
 +
Extract the archive and then take the user folder and put that to the latest build
 +
 
 +
(This is a ogl 3.3 fix using mesa driver). Then extract this archive using 7-zip (don't use this as your citra this is an old version. Compatibility is very low and speed may be terrible in your device). Copy the 'user' folder you see on that folder, download the latest citra version on to your desktop then paste this user folder there.
  
* [[3dmoo]] is another open-source 3DS emulator, made by experienced developers in the DS hacking scene. It was released shortly after Citra and received similar progress for a few months, but was eventually aborted by its authors after a while.
+
The game changer was the sighax exploit, allowing to dump the 3DS bootrom which includes these encryption keys. This file can be downloaded from the [[Emulator Files#Nintendo 3DS|Emulator Files]] page. You can then use a program like '''[https://gbatemp.net/threads/tutorial-extract-decrypt-games-nand-backups-and-sd-contents-with-fuse-3ds.499994/ fuse-3ds]''' to decrypt games using this file. Simply place boot9.bin in the same folder, run the program, mount the encrypted .cia or .3ds, and find the '''decrypted.cxi''' file inside (usually in the first folder). Citra should be able to load this file without issues.
* [[TronDS]] is a closed-source 3DS emulator, presumably made by the iDeaS author. Little is known about it other than that it can run simple homebrew. It cannot be used for playing games.
 
  
===Emulation issues===
+
{{Nintendo}}
'''The Nintendo 3DS currently has no emulators that play games with all features intact.''' This is mainly because for a long time the hardware was documented only sparingly, and homebrew code execution was hard to achieve. Nowadays, the hardware is better known and homebrew is being developed. Many games boot now, with a few even having no noticeable graphical issues. However, sound has not been implemented. This, along with other various issues, exist that make 3DS emulation not ready for prime time just yet.

The Nintendo 3DS is an eighth-generation handheld game console by Nintendo, released on March 27, 2011 for $249. The original model and the 2DS had a dual-core ARM11 MPCore at 268 MHz and a single-core ARM9, 128MB of RAM and 6MB of VRAM, and a DMP PICA200 GPU. The New 3DS and New 2DS XL models upgrade this to an 804 MHz quad-core ARM11 and 256MB of RAM, along with an extra pair of shoulder buttons and a right analogue stick.

The most notable feature of this console is the use of autostereoscopic (i.e. without glasses) 3D, which can be configured using a slider. This was omitted on the cost-reduced 2DS and New 2DS XL models, which was released due to eye health concerns with children whom Nintendo advised not to use the 3DS's stereoscopic mode (though it is speculated that said advisories were more for liability reasons in case of a health-related lawsuit).

Game images[edit]

3DS vs. CIA[edit]

There are two big types of 3DS game images currently:

NCSD-type
Includes .CCI (CTR Cart Image), aka .3DS - data on physical carts, can be executed right off the bat, not used much since no one bothered to develop a CFW solution to load them yet (besides converting them to CIA) and only overpriced flashcarts (Gateway/Sky3DS) can load them.
NCCH-type
Includes .CIA (CTR Importable Archive) and .CXI - installers that unpack game data to the SD card or the 3DS NAND memory. Some homebrew apps (FBI, DevMenu) can install CIA files on 3DS systems with CFW installed. Digital games are often distributed as CIAs.
  • Note that CTR (Citrus) is the internal code names for the 3DS.

Due to one format being so far restricted to overpriced flashcarts and the very slow Citra development (meaning playing on a real 3DS is still the preferred way to go), the CIA format is preferred in many sharing websites, downloader tools and even tools to dump your own games.

However, converting a CIA image to 3DS format (and vice-versa) is still possible with no loss of content. Read the Encryption section below for a guide.

Some outdated dumping utilities intended for use with Citra (like braindump) produce damaged decrypted 3DS images that can't be easily converted back. No known solution exists so far to fix those dumps.

Encryption[edit]

Most dumps online are also encrypted. This encryption poses no problem for playing game images on a real 3DS since it can deal with that encryption with internal keys included in the bootrom, but becomes a problem when trying to emulate them on PC. Citra cannot play encrypted games, only decrypted games will work. A solution to load encrypted images is for the moment on the back burner and there's not much developer interest for it. If you want to play games on Citra, you'll have to convert your game images to that format.

Formerly, decrypting those ROMs used to require real 3DS hardware (bafflingly enough, Citra devs still ask users to do this even nowadays). It required files generated by a real 3DS called xorpads unique to that game version, using the encryption engine within the 3DS. After this part, these xorpads (which are big) can be used with PC tools (or other 3DS-based homebrew) to produce the decrypted game image. After that, some 3DS homebrew (Decrypt9, GodMode9) included tools to directly convert encrypted images to decrypted images with a single button press, but those still require a real 3DS.

But now this new feature was added to citra enables the user to play encrypted games without decrypting them. Read this page [1]

Then, go to this reddit page and copy the code from second comment (credit floppydoppy2) [2] copy it ,make a new .TXT file names 'aes_keys.txt' Then you might have that user folder for citra, then open it go to sysdata , assuming that you have a shared font.bin file there paste this AES keys.txt there. Now user folder is what is the system archive of 3ds you need it to display video Now put user folder in folder of citra or in c: drive (see some YouTube videos , read some reddit posts you will understand it) For user folder:- [3] Extract the archive and then take the user folder and put that to the latest build

(This is a ogl 3.3 fix using mesa driver). Then extract this archive using 7-zip (don't use this as your citra this is an old version. Compatibility is very low and speed may be terrible in your device). Copy the 'user' folder you see on that folder, download the latest citra version on to your desktop then paste this user folder there.

The game changer was the sighax exploit, allowing to dump the 3DS bootrom which includes these encryption keys. This file can be downloaded from the Emulator Files page. You can then use a program like fuse-3ds to decrypt games using this file. Simply place boot9.bin in the same folder, run the program, mount the encrypted .cia or .3ds, and find the decrypted.cxi file inside (usually in the first folder). Citra should be able to load this file without issues.
