[Nintendo Switch] Raika Azahar - The 3DS Emulator aimed at base Nintendo Switch

Raibatsu · 2026-08-07T06:39:15+00:00

------ Thank you so much, Noihs for providing the incredible Fedora-donned rat eating a citrus ------ Many of you may know me through Raikopon - which was a fork of Dekopon, which was aimed at experimental code for the sake of speed & testing purposes. It got a lot of good feedback and the good vibes from many people amongst both this community and Discord made me want to think about 3DS emulation seriously - with better architecture. I present to you - Raika Azahar - a fork of Azahar - aimed for Nintendo 3DS emulation on the Switch with people running on stock speeds. I know a lot of you overclock your console but I personally do the opposite mostly - run at as low power as possible to conserve battery life. I am sure there are many of you like me out there. Therefore, this is a fork aimed at those people that want to maximize how many hours they get before running out of charge. The first build of Raika Azahar has already been live for a couple of days now - on the same page as Raikopon. However, I wanted to make a formal, better post here so we can refocus on Raika Azahar and one day, make this the most stable, easy-to-use, feature-rich 3DS emulator for our beloved handheld console. ============================== What makes Raika Azahar unique: ============================== Async Shader Compilation - First one to implement it in fact! Very proud of it. We are making massive strides toward eliminating shader stutter. Moving from Raikopon v1.0 to Raika Azahar v2.0 has already achieved over a 90% reduction in shader compilation time, while significantly cutting down the overall number of shaders that need to compile. Direct On-Device Cheat Editor - No need to hop onto a PC—you can now write, edit, and manage your cheats directly on the console UI. Direct On-Device Mods Manager - After copying your mods to adequate location, you can easily manage your mods on your Switch. Fully Customizable Dual-Screen Layouts - Complete freedom over your display. Adjust screen sizes, drag them around, tweak opacity, change rotation, or hide/show screens using touch or controller inputs. Built-In App Updater - Stay up to date without ever leaving your Switch. Download and install the latest builds seamlessly in-app. Experimental Features & Performance Hacks - I love pushing the limits and trying new ideas! Raika introduces experimental features like Ubershaders, an enhanced FMV hack for smooth video playback, and granular per-game settings. Cross-Fork Integration & Community Driven - I’m continuously porting and adapting the best features from across the scene (Citra-MMJ, Azahar, Tico, and more) to bring them together into one place. If there's a feature from another fork you'd love to see brought over, drop a comment below! ========= Features: ========= Most 3DS games that are aimed at 30 FPS run at full stock speeds at 1x resolution. There are some exceptions which run at horrible performance and require tweaking. I plan on adding an in-device community-driven compatibility poll too. True async shader compilation that provides a seamless, good experience while playing games. You will experience some huge stutters at the start of your first boot. These are the biggest hurdle left. After you compile these shaders once, the gameplay becomes infinitely smooth. Per-game configuration options so you can make separate configurations for each game. Very feature-rich in-game settings overlay that allows you to change many settings and make custom layouts. Experimental features from other forks such as Fastmem, Async GPU, Skip Slow Draw, Skip Texture Copy, Skip CPU Write. Thanks Dekopon, Citra MMJ for providing these features. They will be rewritten to provide stability in the future. Ability to remap your controls on-the-go. This is one-key only for now. We are going to add multi-key support to these in the future. Install CIAs - apps, updates, DLCs right on the emulator. Ability to clear shaders on-the-go if you are having visual corruptions. No one likes constantly going to the file manager to delete/edit files. Very fast, very lean NXVK | Vulkan backend for Nintendo Switch. This is only the tip of the ice-berg. We are going to have a whole lot of features in the future! The project is currently in the process of a huge rewrite, as was mentioned in my Raikopon post. ============================== Latest Version: 2.5.0 | 18/08/2026 ============================== Downloads: GitHub | Releases Source code: GitHub | Source Code <- This source code reflects Raikopon right now. The current Raika Azahar changes are extremely experimental and will be released as soon as the code has been finalized. ROMs default location is /switch/azahar/roms/. Default location for emulator is /switch/azahar/. I ask that you keep a separate location for Raika Azahar from your other Azahar forks to maintain maximum compatibility. At max, I recommend separating the shaders and config folders. These will cause conflicts and crashes! There have been a lot of requests regarding keeping a separate folder for save files. I plan on adding that in one of the upcoming updates. =========================== Recommended configuration: =========================== - Turn Async Shader Compilation to ON. - Turn Ubershaders to OFF. - Turn Compile Boost to OFF. - Set Async GPU to OFF. - Ensure both hardware Shader and Disk Shader Cache are ON. - Disable Right Eye Render should be ON unless a game demands it. - CPU JIT should be ON. - Fastmem should be ON. - Skip Slow Draw, Texture Copy, CPU Write should be OFF by default unless needed in some games. - Set "New 3DS Mode" to OFF unless a game needs it. Toggling this option causes huge performance drops in some games. Please note that I will not be providing any support if you are using cheats or mods. Have a lovely day to all of you!

So, I saw how crowded the Boot Logo thread had become, and it's mostly people asking for their logos to be created or updated to the latest version. I have created a GitHub repo to do this for you.

Introducing: NX-BootLogo-Generator

What does this do?
This repo allows you to upload your own boot logos and it will automatically convert the images to a zip file, ready to be extracted to your SD card. Everything is done automatically, all you have to do is upload the file.

How do I utilize this?

Sign into GitHub (you must have or create a GitHub account in order to utilize this tool; it is impossible to contribute to GitHub anonymously, and I don't have the (mental) bandwidth to host my own Git (I have a lot on my plate already).
Navigate to the Repo or click on the link above.
In the upper mid-right section, click "Fork".
Supply a repo name (you may use the default) and click the green "Create fork" button.
Wait a few seconds, the page will auto-refresh when the repo has been successfully forked.
Click on bootlogos
In the upper right, click "Add file" and "Upload files".
Upload your files and click the green "Commit changes" button.
The screen will refresh when completed.
When you return to the repo view, press "Contribute".
Press the green "Open pull request" button that just appeared.
In the title box, type the name of your boot logo, and click the green "Create pull request" button.
Wait for your pull request to be approved automatically. It will intially state it is blocked; this will be overwritten when the rule is processed. Once you see the purple "Pull request successfully merged and closed" box, you should wait 30-45 seconds.
After 30-45 seconds, return to the original repo (click the link at the top here). Click on patches/22.5.0, and you will find a zip file with the same name as the PNG you uploaded. Click on it.
Click the "Download raw file" button.
Save the file to the location of your choosing, extract as you would any other zip file, and copy the contents to your SD card (the hierarchy is already set; copy the whole atmosphere folder).

Who is responsible for this?
Impeeza has been manually running these for a while now; I saw the amount of back and forth and decided to automate the process. So they are the inspiration for the project.
Friedkeenan wrote the python script that creates the patches; without this script, none of this would be possible.
I took it upon myself to make this process a little simpler for all involved.

Hope this helps someone. Please let me know if you encounter any issues. ~~The python script I believe has checks built in to ensure the correct file type and image size are provided, but my scripts on GitHub do not.~~ The python script will throw an error and stop the PR, so that's that. ~~I may include them at some point in the future, but~~ I'd like for people to take *some* accountability for their part in the process, ensure that the image is PNG, and 308*350. You GitHub screen name will be added to the contributors list automatically, so enjoy that!
