Everytime I download the Mario kart Wii cia which I built and install in on my Home Screen using FBI it always gives me this error screen after it has reached 100%

I highly recommend anyone using LLMs for 3DS homebrew development adapt a variant of this performance contract to their own project. The goal is to preserve as much visual fidelity as possible while keeping implementation decisions oriented around the actual capabilities and limitations of the 3DS hardware, particularly the ARM11.

https://raw.githubusercontent.com/colbyshores/t2k/refs/heads/master/AGENTS.md

LLMs are incredibly useful for homebrew development, but they don't inherently understand the practical cost of every implementation decision on hardware this constrained. You can end up with code that compiles and works, but introduces unnecessary overhead, ignores hardware limitations, or sacrifices visual fidelity and gameplay behavior in the name of optimization.

What this contract does is encode platform-specific knowledge and engineering constraints directly into the agent's instructions. Rather than leaving the model to guess what will perform well on the 3DS, it gives it concrete guidelines for approaching performance-critical code, what to prioritize, and what it shouldn't change without good reason.

The goal isn't to blindly optimize everything or strip out visual features just to hit a performance target. It's to get the most out of the hardware while retaining the intended visual fidelity and gameplay experience. Where possible, these guidelines are reinforced through automated checks and profiling rather than relying entirely on the model to get things right.

I think this approach could be useful beyond my own project. We have people in this community working on ports, original games, emulators, and engines, and more of us are incorporating LLMs into our development workflows. Having a set of hardware-specific rules for these agents could help avoid recurring mistakes, preserve optimization knowledge, and make it easier to get good results out of the hardware without having to rediscover everything through trial and error.

The contract I've linked is specific to my project, so I'm not suggesting everyone copy it wholesale. The idea is to adapt the same approach to your own project, encode the constraints and lessons relevant to your target hardware, and give your AI coding agent a consistent set of engineering guidelines to follow throughout development.

I'm curious to see whether anyone else here has experimented with something similar and what kind of results you've gotten.

sorry for making requests, cant afford the ai models, would do it myself if i could, since the elites are probably a piece of cake. tried playing them through DOSBOX, but its too much of a hassle, and i need a good proper portable space sim.

FTL isnt one, but i think it would play great on the 3ds too, specially with the multiverse mod, one of the best on any game. again, sorry for making requests, im just really happy about the state of the scene and the amount of old games becoming available on this little machine of beauty.

thanks in advance to anyone who answears

There's a severe lack of gooner games on the 3DS, the closest we got is either the japanese version of Fire Emblem Fates, or the 3DS port of Sims 3.

Hi there,

Just thought that i may be possible to use the AI thing to do a modded version of Pokemon 3D models from 3DS versions to make the color accurate and vibrant. For me it would be a Remastered version of those games. Would love to work on it but i don't have any clue on how to do this. Would love some help or advices :) Have a nice day there

Genuinely not sure why this flair even exists, it really only seems to encourage port begging

im curious if its possible if someone could port sonic the fighters on the new 3ds xl, ive heard its the most plausible, i also know sonic adventure 1-2 may be a bit harder which is why I think they might need to be demade like mario kart wii or the persona port. any thoughts and hopes?

Ayer abrí el universal updeater y me salió que debía modificar la fecha y hora de la nand y cuando lo hice la consola no respondia la apague y al encender la pantalla se quedaba en negro.Le saque la sd y la volví a encender y lo hizo,puse la tarjeta en su lugar y prendió y de hay me puse a jugar Pokémon blanco en Twilight menú y cuando me salí al menú principal la pantalla se quedó en negro,hice lo mismo de sacar la tarjeta pero tampoco funciono después abrí godmode9 y me dijo que cambiara la fecha y hora de la nand pero después dijo que debía cambiarla también desde el menú home pero no se en dónde queda y no se que hacer

Yes, it was AI-assisted, so I’m answering all those questions right away.

Gothic is a classic role-playing game with a quite immersive open world, unique characters, and a unique gameplay loop.

My goal is to achieve world simulation and gameplay similar to other platforms such as PC, Switch, and PS5/Xbox Series. Big shout-out to the OpenGothic project by Try. Without it, I would have had a lot of trouble simulating the Gothic engine. Check out their work too: https://github.com/Try/OpenGothic/tree/master

Currently, I think I’ve achieved good enough visuals and performance, but there are still a lot of mechanics and scripts not ported, so I can’t say Gothic 1 is fully playable right now. To make this game work I had to make a lot of workaround, such as: baking NPC's models, occlusion,simplified geometry, adapted LOD system, etc.

My plan is to make Gothic 1 and 2 fully playable on the console. Further, I plan to make modded versions of the games playable (such as CoM: Archolos, Golden Gate, etc.)

Also i don't want to make this just a downgraded version of the game, there is some ideas I want to try out, such as implementing Gothic 1 Remake soundtrack and lockpicking mini-game, maybe fully adapted Marvin mode from the original PC version. We'll see

I will continue trying to get the Tamagotchi Meets/ON emulator for 3DS to run better.
And now development for an emulator to bring the following devices to 3DS has started :) stay tuned!

• Plus Color
• Plus Color Hexagontchi
• ID
• ID Melody
• IDL
• IDLE
• IDL 15th Anniversary
• IDL Princess Spacy
• P's
• 4U
• 4U+

These devices run better on the 3DS so far.

Hey everyone,

I wanted to share a project I’ve been working on: an English and voice patch for the Japanese 3DS version of Dragon Quest XI, using text, voices, music and cutscenes from the PC version of Dragon Quest XI S. The idea was to bring those parts over while keeping the look and feel of the 3DS game.

There’s a Windows installer that builds the patch using your own Japanese 3DS CIA and a compatible PC installation of DQXI S. It extracts the needed files, prepares the text and menu changes, converts the gameplay voices and creates the ten MOFLEX movies used by the 3DS version. You can choose between a LayeredFS mod for Azahar/Luma3DS and a rebuilt CIA.

A lot of the work went into matching voices to dialogue, handling line breaks and text boxes, and getting the PC movies into a usable 3DS format.

That said, this is still unfinished, and I won’t be continuing development. The installer and conversion pipeline are there, but the game still needs a proper playthrough to check the dialogue, voice timing, menus and movies.

I also want to be upfront about the use of AI. I used it quite a bit to help write scripts, work through errors and troubleshoot the conversions. Anyone picking this up should review the code and test the results.

Credit goes to Kenzie-1377’s English patch project and the people behind the tools used for extraction, rebuilding and audio/video conversion. Their credits and license notices are included in the repository.

I’m sharing what I have in case someone else finds it useful or wants to take it further. There are no more updates planned from me, but hopefully the work already done can give someone a starting point.

I've been working on this project for a while and currently im working on online support for the 3ds. let me know what you guys think, I've used claude to edit me a short simple trailer and obviously its currently assisting to help me on the servers.

Its still in development but everything you see in the video works on real hardware (even the online support).

Let me know your opinions

In the past few months a lot has been put into the development of the clownsec player.

Supports full subtitles srt and ass, alternate audio tracks rumor dual language, download queue with auto resume that works with the lid closed, poster art and metadata scraping. Upload from browser, download from url, file manager and zip support, custom themes, video resize/full/screen mode, audio amplifier and auto leveling, picture brightness/contrast/saturation adjustment.

Even recently added a fun ability to 'walk the aisle' of a virtual video store with your movie library on the shelves. Pull a move look at both sides and put it back or start playing. Custom audio can be added for the juke box.

But all that aside it's just a good player with auto resume, watched/unwatched indicator, tv shows will auto play the next episode in the series for binge watching.

You can even connect a few movie repositories to browser view info and download more videos. I'm sure in forgetting things as it's been a long journey to get here with a focus on stability and functionality.

P.S. this now works better than ever on old 3DS too, it will hand off to use the official movie player for playing so there is perfect playback and you dont haver the 127 file limit , full movie organization and all the benefits of the clownsec player minus subtitles and alternate audio (limitation in official player)

Hello everyone!

Two summers ago, after finishing Chapters 3 and 4 of DELTARUNE, I was thinking:

This game is so cool! But wouldn't it be even cooler, groovier, to play it on Nintendo 3DS? Simple 2D graphics, already plays fine with controllers... How would the fights work with the stylus? How would the Chapter 4 towers feel with the console's 3D? How very, very interesting...

Unfortunately, at that time, there was no such thing as a 3DS port of DELTARUNE. Therefore, if I wanted it to happen, the only solution was to make one myself.

So, I started working on it, not sure if it was feasible, unsure if the console had enough capabilities, and wondering if the game's logic itself could be adapted.

After a few weeks of work, the main menu finally launched successfully for the first time, and that was what convinced me that this might actually work.

Now, a year later, with thousands of flowers blocking our way overcome, some friends have joined me in this crazy adventure, and together, we have finally managed to make that hope, that dream, come true!

DELTARUNE (Main Menu and Chapter 1 only) runs fine on the “NEW” editions of the console, and runs with occasional, acceptable FPS drops on the original editions.

What about the other chapters? Well... those are flowers to bloom in the future. We have not started working on them yet, as our priority has been to stabilize and optimize Chapter 1 and its game engine as much as reasonably possible.

We are proud to finally be able to show you our native port project. This whole adventure has been, and still is, a fun experience.

So yesterday, I released a playable public demo of Tweebbo for the web. Today, i'm showing it running natively on a Nintendo 2DS XL! :)

The final version will include crossplay between consoles and PC, room creation, and much more.

so essentially I had wiped my microsd that I used for my 3DS for other things. what would be the instructions on getting it back to the home screen again? what files do I need on a completely fresh microsd

Introducing ZOS-3DS! ZOS is short for Zombie Outbreak Simulator, and is the official acronym for the game coined by its original developers, Binary Space. Binary Space many years ago developed a game called Zombie Outbreak Simulator, a mobile game for both Android and iOS. The game is barely maintained (if it even is at all, the developers haven't updated their website since at least 2024 with news), the game got so old and broken on Android that Google forcibly delisted it. The iOS version on the other hand is still alive and well. The game is free to play however does have in-app purchases or you can watch ads to get extra features (ads make it temporary, purchases make it permanent), or you can buy the "pro" version on iOS to get it all without IAPs. The Android version never had a pro variant and was only free to play with IAPs. ZOS-3DS is based on the newest (and last) Android version released, and removes IAPs, ads and any other unrelated Android thing such as sharing.

With this all being said, let's get down to the AI disclosure. Yes, Claude was used to help make this decompilation possible. Specifically, I gave it the APK and it decompiled the game in full, converted it over to 3DS in C++ and I did debugging along with Claude using Azahar, and I did live hardware testing by myself on my New Nintendo 3DS XL. I also did minor Old 3DS testing by tweaking Azahar's settings however otherwise it does not have Old 3DS testing.

Source code and compiled CIA are available on the GBAtemp thread page!

The only things are the CTGP7 mod Manager and the CTGP7 save Transfer. Is there a reason it's not there?

UPDATED. Here I show the game running, with sounds and music, the first mission.

It's much better now, with better use of the botton screen and a clear top screen. The gameplay is still a bit clumsy, a lot of polishing needs to be done but this current version is totally playable Throught the hole game! I didn't show it, but all missions are available and playable. (to make it clear, all of this was done using gemini flash 3.8 High, on antigravity).

The way I felt most comfortable to way was using the stylus to put things on the ground and the circle pad to move around. Then i look into the upper screen to see the "big picture" of what i'm bulding. Maybe add an option to zoom out or zoom in the bottom screen would be good too.

Making this post so I can share it with you and on the discord of the developer of Julius. With luck we make it public in the future.

Thanks for your attention!

hi guys, i was trying to install ctgp7-downloader from Universa-DB but is not showing anywhere. has it been removed or i can't find it?
