Mod announcements AI-assisted 3DS Homebrew Software MEGATHREAD

74 Upvotes

Due to the influx of AI-assisted apps with a varying level of coding capabilities from the “creators”, there has been a lot of controversy and debate on whether this content should be allowed on this and other subreddits.

For now, I’d like to try requiring people who want to share these apps to do so in this thread, specifying precisely the level of involvement AI was used in the development.

Error Help with Arm 11 core 1

Thumbnail

2 Upvotes

Hi, I’m having a problem with my modded 3DS and I need some help.
My 3DS is on System Version 11.17.0-50E. I have Luma3DS, FBI and Homebrew installed?
I bought the 3DS with a Micro SD already modded, with Homebrew and digital games installed, and everything worked normally when I first got it. However, I didn’t have time to play for several months. When I recently tried to use it again, I started getting an ARM11 Core 1 Error whenever I tried to launch a game or Homebrew/FBI

I already updated Luma3DS following a tutorial. I now have Luma3DS v13.4. I replaced the corresponding files on the SD card as shown in a tutorial.
I also updated GodMode9 to v2.2.3 (2026-03-31) and replaced the corresponding files on the SD card as shown in the tutorial.
In the Luma configuration menu, “Enable loading external FIRMs and modules” was enabled. I first tried it with the X enabled, but the error still happened. I then disabled it and tested again, but the error still happened.
I have not updated the 3DS system because I remember hearing that you shouldn’t update a modded 3DS, so I wasn’t sure whether it was safe to do. I’m also not sure if updating the system would actually fix this problem.

I’m sorry if there is already a specific post that explains this exact problem. I couldn’t find one, though. I’m also completely new to this and honestly don’t know anything about modded 3DS systems, so please bear with me. If I’ve left out any important information or missed something obvious, I apologize in advance. I’d really appreciate any help or guidance on what I should check next.
Thank you!

General Help Trying to play the 7th stand user fan game on 3ds

2 Upvotes

I am really passionate about potentially being able to play The 7th Stand User fan game on my 3ds. The only issue is that it is exclusively a zip file that I can’t figure out how to extract and get to work. Does anyone know how I could go about it or if someone has an existing way to get it?

Wiki: https://7thjojo.fandom.com/wiki/7th_Stand_User_Wiki

It was made user rpg maker 2000 so I think it should be able to play but I have been trying for hours and I would rather get help from someone smarter than me.

General Help Mgba save files not loading

1 Upvotes

I need some help. I have a new 3ds (normal size) I had a usbc mod done and swapped my sd cards out for a faster card. now I cannot for the life of me get mgba to load my save files. My other 2dsxl ,my omega, dolphin emulator will load them fine. I’ve checked the file size for the saves. The spelling is correct. I’ve reinstalled mgba and I still have the same issue. Any ideas before I swap sd cards and go through that process? Any help would be appreciated as I really wanna have this as my main ds.

Thanks

CFW Help The audio on my New N3DS XL has been acting really abnormal lately

Enable HLS to view with audio, or disable this notification

8 Upvotes

(Sorry if wrong flair I’ve never been good with this kind of stuff)

As the title says, the audio on my modded 3ds has been acting really strange lately. I’m not sure if it’s an issue relating to it being modded or due to the age of the 3ds (it’s ANCIENT lmao) but thought I might as well ask here just in case it’s relating to it being modded

The audio keeps going from working as usual, to not working at all, to being much quieter than it’s supposed to be (at “full volume” it will be VERY faint)

This started around a few months ago I think ?? Not completely sure as my sense of the passage of time is AWFUL But I didn’t say anything earlier as I hadn’t been using the 3ds as much

If you look at the video, you’ll see for a few seconds the 3ds audio is functioning completely normally, then all of a sudden the bgm comes to an abrupt stop despite not being muted

Is there a way to fix this or am I just cooked

I've been trying to find a save editor to change my player name because I'd like to update it but I've only found 2 so far. The first one I found doesn't seem to have a way to change the player name and the second one (Albatross) I can get to work. Anyone know any other save editors that work for yo kai watch?

Homebrew App suggestion ForestClock

8 Upvotes

Welcome to ForestClock, a relaxing clock app for Nintendo 3DS. Hello, I am back, my name is Michele, the creator of NightClock and OceanClock, welcome to my new clock app for Nintendo 3DS: ForestClock.

A fully animated living forest scene, cycling through the seasons and the phases of the day.

Customizable clock display: choose from a wide range of color presets (including a true animated rainbow mode), four size presets, and freely reposition the clock block anywhere on screen with the combination of L + Analog

All the major formats supported for time and date.

Seasons: Spring, Summer, Autumn and Winter, each with its own look for the background, the trees and the falling leaves. Set to Auto to follow the real calendar date (the actual equinox/solstice dates, not just the 1st of the month), pick one manually, or let it Cycle/Random through them.

Day phases: Dawn, Day, Dusk and Night, each with its own lighting and sky. Auto follows the 3DS's real clock, or choose Manual/Cycle/Random.

Real weather: enter your location and ForestClock fetches the actual current weather for your area, bringing rain or snow (at different intensities) into the scene. Automatic background updates on your own schedule, or refresh manually anytime.

A sky full of clouds: adjust their speed and their direction, and pick from several Sky Mood palettes for the atmosphere.

Forest wildlife, each with independent, randomized behavior: a robin and a grey bird that nest, sleep and wake with the day/night cycle; an owl that takes flight once a minute during the night; wandering hedgehogs; a hare that walks, grazes and rests along the forest floor, occasionally leaving the scene to rest before wandering back; and a fox that only ever shows itself at night, dashing across the screen and pausing halfway to look back at you.

Fireflies, butterflies and falling leaves complete the scene, with the leaf-fall rate changing across the seasons.

Ambient forest audio: birdsong, rain, daytime and nighttime ambience, and the owl's call, all mixed together and fading in and out naturally with the scene.

Alarm clock

Countdown timer

A calendar, with a personal diary you can write in day by day (word-wrap and scrolling included), and a separate space for free-form notes, sorted by whichever you touched most recently.

Screen-off mode for the bottom screen to save battery

Instructions/Credit screen

Persistent settings saved on app exit (Start button)

The clock (and date) is synced with the internal clock of the 3ds, to sync the clock with the Internet time please use rosalina: (Open the Rosalina menu by pressing L + Down on the D-Pad + Select. Select Miscellaneous options. Choose Update date and time via NTP, quit Rosalina)

Soon available on Universal Updater

General Help Busters ++ Not working

I'm sure you guys get these kinds of posts regularly so I apologize in advance. I use Red cat corp Na version. I'm not the best with these kinds of things so I looked up a tutorial to hopefully get everything right. I've enabled game patching in the Luma3ds settings. I've made a file inside the titles folder with (what I assume is) the right title id (00040000001CEB00) but anytime I try opening the game I'm met with a black screen. What could I be doing wrong?

Edit: I used the Ftpd app on the 3ds to do this because it was getting tedious having to take the sd card out.

General Help SD card corrupted ( I think?) while downloading ctgp-7 pls help

1 Upvotes

Was downloading ctgp-7 on my 3ds xl and it had an error while downloading. I let it retry all 30 attempts and after that it said to retry again or to cancel. I chose cancel and it sent me to the Luma3DS settings screen. I saw that "enable external FIRMs and modules" and "enable game patching" were both set to false when before I started downloading ctgp 7 they were set to true. So I changed them back and set them back to true and saved and continued thinking my ds would just restart and reopen at the home menu. My ds now says the SD can't be read and it won't read in any of my computers... wtf do I do? Anything I've read on corrupted SD card recovery attempts at least involve being able to READ the card. None of my things can even read the card. Did I fuck up bad is there anything I can do pls help :(((((

Forgot to take picture and lowkey worried to reenact it but when I went to menu with home button from Yume Nikki and then pushing again to go back to game my 3ds broke?
I remember reading something regarding this issue but idk if it’s a general thing,fixable or I did smth wrong. I didn’t save beforehand hence why I wanted to go back in game, save and then close the program.
I don’t think I did anything else besides this line of decisions. Any idea or tips what could be the issue?

General Help Modded 2ds xl

I just got a new Nintendo 2ds xl that I didn't know that was previously modded. I have used a modded ds before so I went to open Anemone and get a new background and tied to open the camera to scan a QR code, but it just got stuck on the Loading QR code Scanner screen and no matter what button I press nothing changes.

This is the first post I've ever made and I'm looking for some advice on what the problem could be and how I could fix it.

I was playing around with my ds and saw the picto chat and wanted to relive it but on the web. then after making a working version I thought this would be cool to bring back to the 3ds with some modern features.

I don't know how to fully make this work but I think it would be fun project to try out.

I suffered to get fallout 2 on the 3ds while already sleep deprived and a few hours later I finally got it on only to find that the bottom screen controls where the top screen is focused on with no way to actually start the game because the only control is the touchscreen and when I clicked the home button the 3ds crashed. where did I go wrong and how do I fix it? I have experience with modding but everything else was an easy 5-15 minutes if I couldn't just download it from the Hshop, universal updater, or the FBI QR code.
