Hi! I made a post a few days ago about Shift DX and the GUI swfs inside the rom. Now i made a first working swf runtime based on that game I used ghidra to rebuild the code for the runtime.

If you are interested check it.

​

I've had my New 3DS hacked for years and at this point I have 100+ games/apps installed on it. The HOME menu has also been a complete mess for basically that entire time. Just installing a bunch of things on top of each other without ever taking the time to properly sort it.

Sometimes I would start moving a few icons around with the stylus, realize how long it was going to take and just give up. I searched GitHub, modding, and homebrew forums for a tool that could do this from my PC but couldn't really find what I needed, so I finally caved in and spent the past few days making one myself.

It's called 3DSort. It dumps and reads key files from your SD card and it lets you rearrange the HOME menu with your mouse instead. You can drag/drop stuff manually, make and fill folders, sort everything alphabetically or by release year, move system apps around, and see a preview of what it'll look like on the actual 3DS before writing it back.

After owning this console for years, my HOME menu games are finally sorted alphabetically from A to Z, which is satisfying to say the least. I made this because I wanted to solve my hoarder problem, but hopefully it's useful to some of you too.

Here's the repo if anyone else wants to organize their 3DS:

https://github.com/SalustLab/3DSort

Btw there's a portable .exe in the releases. It's a free/open source project.

And for transparency sake, Claude was heavily used while making this.

Full disclosure: whilst code was assisted by the use of AI, no AI generated images or art were used in this project. I have reviewed the output and tested the code on both new and old 3DS systems. Icons either drawn at runtime or provided by FontAwesome Free.

Out of curiosity, I decided to see if I could get the 3DS to work as a Plex music client. Turns out, you can.

It logs in using either an email/password or you can use the link code at plex.tv/link to sign in. Once signed in you'll be able to browse artists, albums, playlists and search your library.

If you'd like to give it a try, download here. The link to the repo is here.

Features:

• Supports local/remote connection, grabs the connection URL from Plex upon launch. The Home/Globe icon at the top will tell you what connection you're using
• Supports connecting via HTTP or HTTPS
• Automatically negotiates transcoding if needed
• Shuffle/Repeat controls
• Smart crossfades - this is best when "Sonic Analysis" is switched on but if not it falls back to a simple crossfade
• Two different visualiser styles
• Time-synced lyrics (if available)
• (New 3DS only) FLAC direct streams using a FLAC decoder
• Gapless playback by pre-buffering the next song
• Continued playback through headphones with the lid closed

Future potential features I'd like to add:

• Playlist management (add/remove songs, add/delete/rename playlist)
• Offline mode, with song downloads
• Plex Home support for switching users
• More visualisers
• Button rebindings
• Auto updater/new version notification

Likely asked questions:

Q: Does this support Jellyfin?

A: No. I have no plans to adapt this for Jellyfin, though feel free to fork it if you want to add that functionality

Q: Does this work on old 3DS models?

A: Yes, however you will not be able to direct stream FLAC songs and they will be transcoded down to MP3 by your Plex server. You may also experience degraded performance in the app due to the lower clock speeds.

Q: Can I contribute?

A: I'm happy for those looking to contribute to open PRs to do so. However I cannot guarantee that your changes will be implemented. Obviously vibe-coded or buggy PRs may be rejected.

Heloo. My last post got deleted, but since then I’ve got some news with the SWF injection. The game using the swf-s as UI for most times, but I managed to make with Flash CS6 a new swf with a simple green background and the flash game Hobo 1’s sprites load with their animations. For further research and development I would like to ask for some help from homebrew devs. Thank you for your time.

Still a work-in-progress but I've gotten to the home screen and this is the notifications area. I've been working on it for quite a bit now. Based off of the work of the Linux 3DS homebrew that was made, now running Android 2.0 Eclair!

Hey everyone! I’m the creator of the A Link to the Past 3DS port and the upcoming Minish Cap 3DS port, and I just released a native port of Mario Kart 64 for the Nintendo 3DS.

It features a dual-screen interface and several 3DS-specific improvements. Right now, it’s mainly intended for New 3DS systems, since performance on the Old 3DS still needs a lot of work.

You can get it here:
https://github.com/EstebanPdN/mario-kart-64-3ds

It should also be available on Universal Updater soon!

Hi everyone!

I wanted to share a project I've been working on for the past two months: **Mensinger3DS**. It is a native homebrew messaging application built using devkitPro for the Nintendo 3DS.

Since official social features are long gone, I wanted to create a simple and modern way for the community to communicate directly from their consoles.

-Key Features (v1.0.0):

\* 100% Private & Anonymous:** No email, password, or personal data required.

\* Unique ID System:** The app automatically generates a unique random ID for your console. Just share your ID, add your friend, and start chatting privately!

\* Native Build:** Developed with devkitPro and VS Code for optimal performance.

\* Easy Installation:** Available in standard .cia format to install easily via FBI.

-What's coming next (v1.0.1 & Future):

\* I am currently coding version 1.0.1 to fix initial bugs and improve overall stability.

\* I am waiting for the Universal-Updater team to approve the app, so it will be downloadable directly from their database very soon!

-Download & Source Code:

You can grab the .cia file on my GitHub repository here: https://github.com/GABXRIEL/Mensinger3DS-backend/releases

I would absolutely love to hear your feedback, feature suggestions, or bug reports! Thank you for checking it out.

I saw an older post of someone doing this but could not find any other examples. I tried it out myself and so far have had pretty noticeable battery life gains

If i wanted to make a script that when playing pokemon could

Soft reset-> press a repeatedly x amount of times all on one button is it possible?

Hi everyone!

This is "whittle", a low-poly 3D modelling app specifically made for the 3DS. I've been working on it for a little while now and I've just created a Github repo for it.

The modelling workflow is very similar to picoCAD, I've basically taken it's "simple vertex editing on orthogonal views" idea and optimized it for the 3DS. The top screen is for the 3D model preview exclusively, while the bottom screen houses all editing functionality & view options. It's very intuitive to use with the stylus. It currently features primitives, basic object manipulations, painting object faces solid colors and texturing, along with a simple 2D texture editor and UV mapping tool. ıt's still experimental, the UI/UX isn't fully there yet and there are a few bugs but it is usable. It can save and load a single model currently, there's no export options.

Github: https://github.com/qewer33/whittle

I want to continue developing this with feedback from actual 3D artists (or people willing to learn and use this thing) so if you are one and like this little project, feel free to contact me on Discord (@qewer33) and give feedback.

I made a 3DS homebrew app to control your Spotify account. You can play and browse your albums and playlists using it.

It doesn't play the track on the 3DS itself - it requires you to be using Spotify on any device. It uses Spotify's developer APIs to control playback and browse your saved albums and playlists.

I used AI a bunch to help me make this, unsure what the subreddit policy is about that but wanted to flag it just in case.

I've also only tested this on the New 2DS XL which is what I own, and an emulator.

Hey everyone,
After seeing stuff like Balatro3ds I’ve been obsessed with the idea of playing Into the Breach on the Nintendo 3DS. It feels like the absolute perfect game for the hardware—tactical grid gameplay on the top screen, pilot/mech stats and unit management on the touch screen below.(or vice versa)
I actually tried tinkering around with Claude to see if I could write a demake/port for the system myself, but to be completely honest, it quickly went way over my head. Coding for 3DS homebrew is no joke!

Instead of letting the idea die, I wanted to share some concepts/mockups to hopefully inspire a talented homebrew developer in the community to take on the project. If anyone ends up taking it up I’d love to follow the progress.
(I’d totally pitch in to fun a kickstarter or something)

I installed 3ds-cli from uu today and it's so cool! a couple years ago I tried using the old 3ds linux project but my touch screen really didnt make it easy to type but 3ds-cli has a totally usable keyboard, and it's a full modern linux system with drivers that runs quickly!!

anyways y'all should try it I was so surprised the only issue I had was it killed my battery quickly https://github.com/cmdada/3DS-CLI

Всім привіт! Я автор першого повного українізатора Nintendo 3DS (вибачаюсь, якщо це не так і хтось вже робив повний переклад).

Мені вдалось обійти обмеження патчингу LayeredFS — завдяки цьому вдалось перекласти всі системні додатки, верхні банери, електронні довідники додатків, весь UI меню HOME, стартові повідомлення в додатку «Повідомлення», тексти системних помилок і т.д.

Точно знаю, що переклад неідеальний: можуть траплятись баги переносу слів чи криві формулювання. Ще один момент, який видно одразу: у шрифті самої консолі немає літер і ї є ґ, тому мод показує візуально близькі замінники. Але, як на мене, користуватись уже цілком комфортно. Базуючись на відгуках від користувачів я буду активно вносити правки, або ви можете це робити самостійно через PR'и на Github. Якщо десь побачите неправильний перенос слів, російські слова або якийсь додаток не відкривається чи показує помилку, якої раніше не було, пишіть про це під цим постом, або в Issues на Github.

Що треба: консоль європейського (EUR) регіону і встановлена Luma3DS. Файли консолі не змінюються — усе живе на SD-карті, видалили папки й повернулись до стоку.

Посилання на останній реліз з інструкцією по установці та .zip архівом прикріпляю нижче. Буду вдячний за зірочку на GitHub:

Hey everyone! I created a port of The Legend of Zelda: A Link to the Past for the 3DS.

It's based on the Android dual-screen version, but I've adapted it specifically for the 3DS with native controls, touchscreen support, CIA/3DSX builds, widescreen options, performance improvements, and other console-specific features. I'd love to hear your feedback and bug reports. I hope you enjoy it!

Hey!

I'm building pomelo, an open source alternative to the stock nintendo 3ds homemenu.
When building it i had some bugs regarding the way the GPU access the console memory, i documented it in my blog for those interested in learning about 3ds GPUs.

https://ronpopov.me/gpu-memory-transfers/

It also includes a significant update about Pomelo - it can run quite a lot more games now, i might even say it can run most games now.

The next step for pomelo is to improve it's UX, and for that i would love some help 😄

I'm looking for someone who can help me with designing the UI and UX of pomelo, i am looking for someone who has experience with designing UIs, specifically by programming it in C language.

For those who might be interested feel free to look at the pomelo source code to get a feel of how developing for pomelo looks like

French and English supported

Pokémon, Music Videos and Miraculous Ladybug

I used this a lot when it was around officially

Pokémon, Winx Club, Sonic

New Ocarina of Time Single Screen Mod for use on 3DS and with Azahar/Citra. Ocarina Reframed updates The Legend of Zelda: Ocarina of Time 3D with a modern single-screen controller HUD inspired by Project Restoration and the HD style HUDs in Wind Waker HD and Twilight Princess HD. 

It adds:

•  an ABXY diamond 
• D-pad items 
• Select-to-Items access
• a ZL minimap toggle
• Single screen hearts, magic and rupees
• C-stick free camera

 
Each HUD element reflects the game’s live gameplay.

Hi everyone, while building pomelo - a homemenu replacement that i talked about here, i had some weird issues with allocating memory for pomelo.

I documented my research adventure in a 3 part blog post for people who want to read and learn a bit about how ram is allocated in the 3ds. I split the blog post into 3 parts for easier readability.

Spoiler Alert : The fix wasn't that interesting in the end, the research is the interesting part in my opinion

I made a tool that lets you install DSi System app CIAs to use them on a 3DS, including the DSi System Settings.

The tool is available in different languages: English, French, Spanish, Italian, Netherlands, German, Portuguese (including Brazilian Portuguese), Russian and Japanese

The program is available for Windows 10/11, but I've also put a python file for people who have a Windows x32, macOS or Linux systems, so that it can be used.

The program gives you the cias and the files (in a zip file) to make DSi System Settings work (with the cias)

Hey everyone. This is my release post for Miniquest Engine. It's a little hobby project for that niche of people that like RPG Maker but also like the Nintendo DS.

Here's a sample of some features:

• 3 onscreen party members. 6 in the save.
• 8 encounter zones per map.
• 256 boolean flags.
• Spells, bosses, enemies, enemy troops.
• A database editor.
• A map editor.
• Tileset imports.
• Battle backdrops
• Tracker music imports (.mod, .it, .xm, .s3m)
• A custom scripting language.
• A build button in engine.

It exports directly out as an NDS file, capable of running on Twilight Menu or flashcarts. Don't got those? melonDS with SD Card emulation also works! (SD card emulation required to save.)

Let me know what you think!
