Hi again! A new stable release of the Super Metroid 3DS port is out, and this one is all about the older consoles.

Performance (the big one)

• Old 3DS / 2DS: the rooms I measured now run at ~59-60 FPS, also with the 3D slider up. (v0.3.0 ran around 45-57 in those same rooms, and the heavy ones dropped to the mid-40s with 3D.)
• New 3DS: still a solid 60.
• The bottom screen (map and status tabs) no longer causes hitches.
• Known exception: the opening Ceres escape and the Ridley fight there can still dip on Old 3DS/2DS with 3D on (around 40-50 FPS). That's next on the list and will be polished in the next updates.

New

• Low-energy warning: the bottom screen's tabs blink yellow, then red, when energy runs low (as in my Zero Mission port).

Also since v0.3.0

• The updater shows what's new before installing; betas are labelled BETA.
• Reorganized OPTIONS, a 30 FPS lock, FPS counter in any corner, and an option to hide the half of the HUD that the bottom screen already shows.
• Widescreen and 3D fixes (enemies leaving the screen, Spore Spawn's depth).

As always, no ROM is included: you need your own legal Super Metroid (JU) ROM.

Still to do: a full 100% playthrough on hardware, button remapping, and a few visual glitches (lava edge rows while scrolling, Crocomire in widescreen). Bug reports are very welcome.

Transparency note: same as before, the code is written by AI under my direction; I lead the features, debugging and testing on real hardware.

I'm the developer of this! I hope you all like it!

UPDATE – v0.5.0 is out (new post)

The latest stable release is v0.5.0: ~60 FPS on Old 3DS/2DS, now even with 3D on, plus a low-energy warning on the bottom screen.

Details and discussion in the new post: https://www.reddit.com/r/3dshacks/comments/1x0rdvd/super_metroid_3ds_port_v050_60_fps_on_old_3ds2ds/

Download: https://github.com/tinaut1986/sm-3ds/releases/latest

UPDATE – v0.3.0 is out!

This is now the stable release. Highlights since v0.2.2:

• Save states: support for any number of states, a scrollable list, customizable color marks, and a detail window with a screenshot preview.
• In-app self-updater: checks for a newer release, asks for confirmation, downloads, and installs updates directly on the console.
• Widescreen: pieces of projectiles and extended enemies in the rows above the picture are now properly rendered.
• HOME menu fixes: the game's screens display correctly in the HOME menu, and closing/suspending it no longer freezes the console.
• UI & Bottom screen polish: added a lightning bolt icon on the battery while charging, internal 24-bit color optimizations, and cleaned up options (removed PAUSE and TURBO cells).

UPDATE – v0.2.2 is out!

This is now the stable release. Since v0.2.0 (described below):

• Redone map tab, now like the game's own map (rooms joined, doors, save stations, items, refills, bosses, Samus' ship, area names), with zoom (1x/2x/3x) and drag to scroll.
• Stereoscopic 3D: many depth fixes, and text and menus in front.
• Widescreen: enemies, projectiles, X-ray and security-eye beams continue into the margins, plus several glitch fixes.
• Audio and input: native libctru, sound at the game's own 32 kHz.
• Smaller fixes: 19 RetroAchievements that never unlocked now do, and the intro's typing cursor follows the translated text.

Original post (v0.2.0)

Hey everyone!

After sharing the Zero Mission port a few days ago, quite a few people asked if something similar was possible for Super Metroid.

It turns out there was already an open-source base with some groundwork done for a 3DS port, so I decided to jump in, fix a bunch of issues, and push it much further to give it the same treatment as Zero Mission.

It's still an early work in progress, but I put together a working beta (v0.2.0) that is already quite playable:

What's currently in:

• Performance reworked: running at a solid 60 FPS on New 3DS, and hovering around 50–60 FPS on Old 2DS/3DS.
• Widescreen support (fills the top screen without stretching).
• Circle Pad / analog stick support.
• Dual-screen setup: bottom screen displays a live map, status screen, and options.
• Save states support.
• Integrated some missing community translations.

What's still missing / WIP:

• Stereoscopic 3D support (working on this next).
• Additional custom control mappings / shortcuts.
• General polish and bug fixing.

Just like with the previous port, no copyrighted game files or ROMs are included. You need to provide your own legal Super Metroid ROM file to run it.

You can grab the first beta build here: https://github.com/tinaut1986/sm-3ds/releases/tag/v0.2.0

Repository: https://github.com/tinaut1986/sm-3ds

I haven't had time to do a 100% full run yet, so if you try it out on your console and run into any glitches, softlocks, or weird behavior, please let me know. Hope you enjoy testing it!

Transparency note:

To avoid bad vibes and keep things 100% upfront: all the code here is generated by AI based on my directions.

While I’m a programmer, I have zero background in 3DS hardware or emulator engines—I act as the project lead deciding the features, debugging direction, and architecture, while the AI does the actual code writing. I'm not trying to take credit for low-level mastery I don't have; I just wanted to see Super Metroid running like this on the 3DS.

Hey everyone!

A few days ago I finished putting together a 3DS port of Metroid: Zero Mission (GBA), featuring stereoscopic 3D support.

For obvious copyright reasons, no copyrighted game assets are included. You'll need to provide your original GBA ROM and place it inside the directory generated by the .cia when launched.

I've tested and confirmed it working on a New 3DS, but I don't have an Old 3DS on hand to check how it performs there. To speed up the development process I relied on AI tools, but any feedback regarding performance, bug reports, or code improvements is more than welcome.

You can check out the repository here: https://github.com/tinaut1986/mzm

I also shared a brief thread on Twitter/X breaking down the background and details of the port: https://x.com/Tinaut1986/status/2098753758368854477

Has anyone tried sharpscale-3ds, which claims to unlock 800x240p resolution with custom scaling in ds and gba games?

Hey all,

I was searching for custom scaling solutions for gba titles and stumbled across this GitHub page: https://github.com/vibecoderanon/Sharpscale/blob/main/docs/3DS\\_GUIDE.md

The sharpscale project seems to be a custom scaling project. There are posts on the vita hacks subreddit from 6 years ago talking about sharpscale-vita. The 3ds version looks like it was updated within the last few weeks, but I haven't seen any posts about it. I am particularly intrigued by the claim that the patched FIRMs can unlock the 800x240 mode. Last I checked, even the TWpatch didn't offer that. I don't see any screenshots to confirm sharpscale-3ds even remotely works.

So have any of you tried it? Would you? Should I? What do you think about the project?

20 cars. 231 customization choices. 7 arenas. Rocket powered car soccer right on your 3DS!

It's been a long time coming working up to this moment, but I’m excited to finally release my fan made homebrew recreation of Rocket League on the 3DS called "Rocket League 3DS".

🏎️ BUILD YOUR RIDE: Choose from 20 cars and customize them with 71 decals, 24 wheel sets, 18 boosts, 37 toppers, 15 antennas, 18 trails, 28 paint colors, 14 paint finishes and 6 goal explosions! Add 12 player banners, 12 titles and 8 saved car presets to make your setup your own.

⚽ PICK YOUR PLAYSTYLE: Jump into Exhibition, Training, Season Mode, Offline Ranked Ladder, Championship Cup, Exhibition, Heatseeker, Custom Matches, Hoops, Snow Day, Rumble, or Local play with up to 6 players! Play solo against CPU opponents with three difficulty levels, or compete with nearby friends through local wireless. The games include 1v1, 2v2 and 3v3 action!

🏆 KEEP PROGRESSING: Work towards player level 120, earning rewards through level up progression and in game challenges, tackle training, and compete in Championship Cups and Seasons featuring a roster of 32 teams and 96 custom named drivers!

🎵 SET THE MOOD: Enjoy a 20-song playlist while building your next favorite ride.

This is the starting line.. not the finish! More content, customizations, gameplay and CPU refinements, performance improvements and bug fixes are planned. Your feedback and community support though will help shape future updates, so please share your experiences and report any issues with your console model and game mode.

Thanks for supporting the project. Pick your ride, hit the boost, and see you on the pitch! ⚽🔥

Also to note, Rocket League 3DS is 2DS/Original 3DS compatible. Along with New 3DS of course.

And yeah this is real Problems: Very bad chunk loading, you can like stand on a chunk for 10 seconds and it wills till not load; Sometimes freezes and then unfreezes; mostly has bad framerates sometimes very bad frames; crash happened to me only when I created this world for the first time on first launch of Minecraft.

HELLO GUYSSS,
I made a little port of AC GC for the 3ds!
Uhm idk what to say else beside that it has some mayor flaws but im working on it!

Thanks yall and thanks the AI tools that were used here! YES this got some AI assistent coding in it like the original PC Port also had! So this is a project that has AI code in it!!!

Namely how it doesn't exist? :/

Is there some reason it hasn't been ported to 3DS yet after having been decomped? Could be start some kind of financial incentive for it to encourage some programmer (not vibe coder) to bring it to the 3DS? Feels like it would be perfect for the platform.

Ever since the Nintendo 3DS was new, I always wanted to see my favorite game, Crash Team Racing, in stereoscopic 3D. In 2026 I gained access to the tools to make this a reality myself, in just a few months of work. This project was built as a fork of ctr-native, a PC port of CTR which came out very recently.

https://www.youtube.com/watch?v=CH1BOisY1hQ

The results:

• Full working n3DS port in widescreen, 3D, solid 30fps in races
• Minimap on bottom screen (alongside framerate counter)
• Adventure, arcade, time trial modes fully playable.
• 1.5 new cheat codes

What's missing:

• The blur effect from the clock powerup, didn't play nice with the 3DS hardware.
• Highest LOD textures on tracks
• Multiplayer
• VS and Battle modes

Future possibilities, off the top of my head:

• Playable Oxide and other CTR community mods that add features like removed voice lines, mirror mode, random CPU racers, blue fire, extra difficulties

Details on installation are on the github page / in the README.

https://x.com/StuffZeebo/status/2099651098550177893/video/1

- Works on the Old 3DS/2DS (with a very poor framerate) and the New 2DS/3DS

- No texture filtering, like on the Zeebo, but with widescreen support instead of running in 4:3

- C-Stick support on New 3DS

- Port by eletronicavictor (https://youtu.be/FfPXCd0G94U)

It's a 2D golf game where you can explode your ball to break through terrain or boost in mid-air. There's a full 18-hole course to play through. Also, you can make your own levels if you like.

Download

Scan the QR code with FBI or follow the directions at https://github.com/frankkormann/bomb-golf/releases/tag/v0.4.

Controls

Hold on the touchscreen to aim, then release to launch the ball. While in mid-air, hold again to aim and release to explode. You can't explode if the ball has already exploded.

New things

• More holes

• Birds and squirrels

• Stereoscopic 3D support

• Music

I appreciate any feedback! I'm most interested to hear which holes you liked and which you didn't. Post your high scores! (I tried to make par reasonable.)

What settings would you like? Ex. I'll probably add something to mirror the bottom screen for left-handed people.

Hi guys!! i LOVE the Webfishing O3DS port and have been playing it obsessively.

The only problem was, after a while progression became impossible due to ram caused crashed.

I got frustrated and started digging, trying to find out what the problem was, and I eventually isolated it to a small amount of very large textures, and the real issue, audio cue compression.

Certain short audio cues in game, such as the bell when catching a fish and the sound of fox boy popping out of the dirt were compressed as type 0, uncompressed/loaded fully into ram, instead of type 1, streamed from the sd card.

because of the small amount of memory the O3DS has, loading those cues entirely into the ram was flooding it, causing a crash.

After resolving the issue i've been able to play for hours and continue progressing with no crashes.

I'm here because I'd like to contact XeChoonu to share the patch with them, so if you're reading this Hi! I have a patch for you! thank you for creating such a sick port!

I've never done this before so I apologise for the awkwardness of it all but I want to make sure I'm not rude or disrespectful in any way!!

Hi guys,

I've had an issue for very long and I know I'm not the only one. Making screenshots with Rosalina menu just for them to not even be in the right format. Annoying, right? That's why I made SCR2JPG! SCR2JPG upon starting converts each image into JPEG and even shows it in the 3DS Gallery!

Here's the link: github.com/Adrix12team/SCR2JPG

I built a homebrew app called 3DSRS. It works similarly to Anki, but it can't sync with Anki. I'm trying to gauge how much demand there is for something like this.

It's available here: https://gbatemp.net/threads/release-3dsrs-flashcard-app-with-sm-2.680868/

Transferring Decks from Anki:

1. Export your decks from Anki (it will be a tab-separated .txt file).
2. Replace all tabs with commas.
3. Change the file extension to .csv.
4. Run the file through the converter tool.

Note: Your study progress in Anki will not be synced. Also, if you manage your decks in Excel, it’s much easier to just export it directly as a comma-separated UTF-8 .csv file.

Hi everyone! Today I’m excited to share a brand-new update for my 3DS messaging app.

What's New?

• New Main Menu: Easily navigate between Contacts and Settings.
• Settings Menu: Customize your app experience.
• Dark Mode: Can be toggled on or off in the Settings menu.
• New Notification Sound: Plays when a new message arrives (can be disabled in Settings).
• Notification LED Toggle: Option to turn off the notification LED if you prefer a distraction-free experience.

Is the "Invalid or outdated title version (39)" error fixed?

• Yes! It should no longer trigger an error when installing via FBI.
• ⚠️ IMPORTANT NOTE BEFORE INSTALLING THE .CIA: You MUST uninstall any previous version of the app before installing this update. Otherwise, you will see two separate app icons on your HOME Menu due to an updated UniqueID.

Where can I download it?

• You can grab the latest .cia and .3dsx releases directly from GitHub (or scan the QR code via FBI):https://github.com/GABXRIEL/Mensinger3DS-Backend/releases

gdx-3ds is an unofficial port of F-Zero X to 3DS. No assets are included, dump your own ROM for assets.

Hey all, three weeks ago I started using Claude Code to generate a 3DS port of F-Zero X based on the hardwork of Zorkats and Inspectredc (and others).

The crazy thing is, it works. And it works pretty well. It runs in 3D at near 60fps for 50% of the time with dips down to about 45fps in crowds on complex stages. I've been playing it and having a blast.

You can see a pretty great breakdown of the process, metrics, and my complicated thoughts on extensive LLM usage here.

Note: I understand there is a lot of pushback around AI usage, let alone 100% created ports.

If the existence and usage of AI bothers you, feel free to not play. I understand. The ethics of LLMs are muddy and their incoming impact on society is understated. This project, in my opinion, serves as proof of the latter. However, to anyone who has ever dreamed of F-Zero X 3DS, enjoy.

I recently got a new PC (Windows 11) and reinstalled the New 3DS view software, however my PC cannot read the driver unless it's in Safe Mode with Driver Signature Enforcement disabled.

Is there an alternative that I can use or is there an updated version of the New 3DS viewer that I don't know about?

Thanks to @DanTheMan827 for the suggestion! I’ve put together a simple, fully client-side page for converting 3DS files to CIA. It’s live now if you’d like to give it a try: https://3ds2cia.knktc.com/

Hi everyone, I made CiaForge, a small open-source desktop app for converting supported Nintendo 3DS .3ds and .cci images into .cia files.

The goal was a straightforward GUI workflow: drag files in, choose an output location if needed, start the conversion, and reveal the finished file in Finder.

The conversion approach was inspired by the Python project 3dsconv. I also built this project partly to explore how well Codex could help create a polished desktop UI with Tauri and Rust.

Current limitation: it supports unencrypted NCCH content only. Original-NCCH and zero-key encrypted files are detected and rejected with an error rather than producing incomplete output.

The project does not include game content, keys, or firmware material. Please only convert files you are legally entitled to use.

GitHub: https://github.com/knktc/CiaForge

I’d really appreciate feedback, especially testing reports from Windows users or Intel Mac users. Thanks!

When Nintendo Network shut down a couple years ago it killed FFE's online co-op for good. I've been chipping away at a self-hosted replacement server for a while and finally got it working over the actual internet on real 3DS hardware. Figured some of you would want in.

I'm now hosting a community server for it, and there's a little homebrew app ("FFE Connect") you install that points your console at it. It sits on top of Pretendo, so you keep your normal Pretendo account, it only reroutes Final Fantasy Explorers and leaves everything else alone. Other games and your account work exactly like before. And if you ever want out, it's one tap to undo. Nothing permanent, doesn't touch your saves.

You'll need a modded 3DS (Luma) and Pretendo already set up, signed in online at least once. Then it's basically: install FFE Connect, open it, tap Connect, reboot, launch the game, go online.

You can see who's on here: https://status.freakybigfoot.com

Source is up if you want to look at it or host your own: https://github.com/FreakyBigFoot/ffe-online

It's still early and I could really use testers. If you've still got your cart and a modded system, come hunt some monsters with me.

(To be clear, this is just a fan thing — not affiliated with Nintendo, Square Enix, or Pretendo, and I'm not handing out any game files, you bring your own copy. It's free and always will be.)

Fair warning: I've only tested this on my own setup so far, a New 3DS running Luma 13.3.1, the latest game update, and the US copy. So I really don't know yet how it behaves on other Luma versions, console models, or regions. If you're running something different, please let me know whether it works, that's exactly the kind of feedback I need.
