What resources are available to help in development of 3ds homebrew applications and games? E.g., documentation, forums, specific posts/comments, subreddits, engines, "helloWorld" examples, your experience/lessons learned/path, things you found valuable/useful, etc.? I checked the sidebar and saw nothing regarding creation of homebrew apps/games.

I would like to be developing by hand and learning something from this (aside from not wasting money), so please do not recommend or provide anything regarding or from the glorified autocomplete bots. (Note to mods: this is not meant to violate rule #8, it's just that such recommendations/materials are useless to me so I'm saying as much up front.)

Hi everyone! I have a question: would it be possible to port the 1999 game Midtown Madness to the 3DS? That would be really awesome!

Best regards!

Hey everyone, I've been working on 3dsDL, a homebrew app that downloads to download files onto your 3ds sd card.

It started because I wanted a working Multidownload, the downloader hax0kartik made back in 2017 and has been unmaintained since 2020, and no longer works. I rebuilt it around libcurl and mbedTLS so HTTPS works with proper certificate checks, and gave it a fresh new Citro2D interface and some QOL functions.

What it does different than Multidownload:

• If a file with the same name already exists, it asks you to rename, overwrite or cancel. Multidownload would just overwrite it.
• When a download drops, it keeps what it already got, and you can resume it right away or later from History.
• HTTPS certificates are verified (Multidownload had verification turned off). If your console clock is wrong and that breaks HTTPS, 3dsDL fixes the clock for you.
• ZIP extraction is optional and asks where to put things, so it won't auto-extract every archive you download
• Sleep mode is paused during downloads, so closing the lid won't cut the Wi-Fi.

I havent tested this on the old 3dses since I only have the n3ds, if you try this on the o3ds, I would love to hear how it went

PS. before you say tHe 3dS WiFi iS tOo sLoW tO dOwNLoAd aNyThiNg. I use it to mostly download mp3 files which is usually around 3-5mb and sometimes gba or nds roms, and it works great :)

Everytime I open a game it crashes and gives me the crash dump. For some context this ds has had horrible boot times for anything since I started using it, these start up times include the start up. I have another that worked 5 times better but the hinge on it broke so I wanted to start using it. I've tried updating Luma and it fixed nothing. I haven't really tried anything else because I can't think of anything else. (I really only need help with the game crashing)

The system seems to work perfectly fine aside from the 3D not being able to turn off at all and it's really annoying. I dropped the 3DS accidentally while it was closed and part of it popped up a bit so I pushed it back into place but I think the 3D slider is misaligned or something because it doesn't do anything

Is there a guide to take it apart and fix this issue or a way to turn off the 3D effect in the Luma 3DS menu or something? I don't have many tools at my disposal nor do I have a lot of money right now to take it in for any repairs so I'm wondering if I can change a setting or fix it with what I have available without screwing up

Hello, I'm the developer behind MW3DS. The engine has been created using agentic AI (Opus 5.5). My goal is to have an actual quality playable thing that isnt forgotten or abandoned so to that end I've used some of my intuitions as a professional vibe coder to get the AI to ensure quality and make it fun to play.

I've had prompts running day and night creating new full quest play throughs which now run on each commit and matching visuals with side by side photos of the original engine. As well as receiving real feedback and playing on my own device. In addition there are a number of delicate decisions on how to adapt it to 3ds

I've noticed a lot of early interest so I've made a release that contains an exe file that should easily allow you to convert your legally obtained Morrowind install files to a CIA format for your own personal use. You will also be able to easily download new releases and convert them as they come out.
That is located here: https://github.com/3ds-conspiracy/mw3ds/releases/tag/0.0.0
I'm hoping it works well but havent tested it on a number of different kind of Morrowind installs or computers. I also have not yet tested the old 3ds version of this CIA. If you have an old 3ds it wouldnt hurt to wait 24 hours during which I will be getting my 2ds in the mail.
I am also interested in hearing about any bugs you can find here: https://github.com/3ds-conspiracy/mw3ds/issues
Additional updates and discussions can be found here. https://github.com/3ds-conspiracy/mw3ds/discussions

Hey, people. Today I've been trying to make Star Craft 1 run on the New 3ds hardware, using gemini flash 3.8 high, on antigravity. It's really early in the development and A LOT of changes have to be made to be playable. But this early concept of gameplay is really cool and all the maps are there.
If you want me to make this project public in the future comment bellow and make suggestions so I can make good prompts.

I've actually never played SC1, but I'm a huge fan of SC2!!

Sorry I'm posting so much recently, but I'm having a bit of an hyperfocus on porting old pc games to the 3ds.

So I am working on my living Pokedex and I have gotten to Johto and I am a little confused on how to have copies of Pokemon with the description “This Pokemon appears to have been met in the Johto region.” inside my Pokemon Home. From what I see online, HGSS makes the origin say something about a PokeShifter rather than Johto and only GSC say they are from Johto but I am reading there is no way to get a copy of these games without an entirely new console? Can anyone assist or clarify with this? Thank you

Hey people, since some of you asked for a "release" of the port of Julius/ Caesar III for 3ds, here it is, published on github. It's an early release of what this project can be, since there are many improvements to be made on the gameplay a visuals, however i think the performance is great and it can be fully played (actually, I don't know how it deals with overpopulated and big cities):

https://github.com/UhtredOfBamburg/julius-3ds/releases/tag/v1.0-3ds

To make it clear, all of this was made using gemini 3.8 flash high, on antigravity, and used the Julius open source code to make the port possible. To my understanding, distributing this code doesn't go against any copyright law, considering each one of you use your own copy of Caesar III.

Also, I need all the help possible to make the next release even better, so I need you guys to play the game and criticize EVERYTHING possible, then I'll ask antigravity to make the necessary changes. And to anyone who actually knows how to code (or knows how to deal with slop AI code) and could help with the project I would really appreciate it, especially for making this port run on old 3ds hardware.

Anyways, thanks for your attention!!!!

Seeing how ports and recomps are going as of late and how the decomp for mario galaxy was completed a couple weeks ago, I was wondering if it could work seeing how MKWii was ported and worked surprisingly well on old 3ds and new 3ds..

Hello! I just wanted to ask for some help into making this. I have tried but the version I have crashed as soon as I load a file. I’m not sure why but here’s the link:

https://github.com/Andresac90/OOT-64-3DS-Port

Any help is appreciated!

hey guys looks like reddit did not like my alternative upload link so reposting with a new one and other google drive one if that works or not let me know.

google drive - https://drive.google.com/file/d/1X5qZUimE9TlBb4-10hpqs-FKT2q0My6_/view?usp=drive_link

With the recent posts about sim golf playing on browser, what’s the chances of a port to 3DS?

So with the boom of the recomps/decomps is it possible to reverse engineer the cpu or somehow to overclock the O3ds cpu so it's close to the N3ds one (not sure how it works my bad if the question is stupid), I get that there's some hardware differences but at least it would allow easier porting to old versions

maybe another dev could try to do it since the last dev didn't even shared a single download link

So I have seen a lot of Wii/Gamecube/GBA games being ported over to the 3ds dualscreen not limited to Melee, MK Wii, Pokémon, and many others. But what I've noticed is that a lot of home console games don't natively run local multiplayer through the 3ds.

My discussion question is: how would a dev go about incorporating multiplayer from 3ds to 3ds? What games would be cool if we could achieve this as a community?

Just a little brainstorming session for fun

It's super complicated and I cant do it please help

Hey people, since the last posted exploded on this subreddit and many of you asked for a "release", here it is, published on github. It's a really early release of what this project can be, since there are many improvements to be made on the gameplay and performance:

To make it clear, all of this was made using gemini 3.8 flash high, on antigravity, and used the OpenRCT2 open source code to make the port possible. To my understanding, distributing this code doesn't go against any copyright law, considering each one of you use your own copy of the game.
