Hey everyone,

I've been working on a side project for a few days now: a port of Resident Evil 2 for the Nintendo DS, built by reverse engineer anything and Claude Code. It's still rough, but the core loop is playable.

What works so far for example:

- The first 2 cutscenes (with Claire and Leon and in the gunshop) - Core Loop: Picking up items, combining them, shooting and killing zombies, getting damaged and dying (You Died Screen works) - Sound effects and music

Known issues / what's missing:

- Music sounds weird for example in the police station - Saving the game, Item Box and save rooms - the DS Rom is already nearly 300MB large but i think it will not get over the Limit of 512MB

Feel free to share! It would be nice to have more collaborators because I'm not the most experienced programmer and only have limited time/resources.

The code is on GitHub if you want to take a look or help. You can follow the Readme notes to create your own .nds File:) Git-Repo

Just modded my 3ds XL yesterday and was wondering where i could find gameboy games?

a little more from this project fully open

Im trying to hack a friends dsi

After selecting region and lenguage it doesn't load, i have left it loading for over an hour and it never loads

It may also be that it isnt in the best conditions, after all its his child-hood ds

Hey everyone. I’ve got some really bad news.

My PC ran into some serious problems, and Windows ended up needing to be reinstalled.

Unfortunately, I lost my local OoT DSi project files in the process along with literally ALL of my other projects.

As things stand, I can’t continue development from where I left off. I genuinely don’t know if or when I’ll be able to pick it back up, and I don’t want to make promises I can’t keep.

That being said, I’ll try my absolute best. This is just
going to be extra difficult to finish the project now.

I really appreciate everyone who showed interest in the project, joined the Discord, or followed the progress. Seeing other people genuinely excited about something I was building meant a lot to me.

I’m sorry I don’t have better news.

I’ve been building Digraph DS, a graph editor and analysis workbench for the Nintendo DS and DSi. It grew from the kts-nds foundation, and the engine work developed during Digraph’s creation has since been brought together in Devy, a reusable Rust, Bevy, and BlocksDS runtime.

That engine work goes well beyond the original foundation: Devy brings together framebuffer and layered 2D drawing, hardware 3D, touch input, gestures and strokes, SD-card storage, NitroFS assets, sprites, audio, cooperative tasks, time and RTC support. It also comes with host-side tools for preparing assets and scenes.

Digraph DS puts those capabilities to work as a real graph editor. The two screens have different roles: edit and manipulate your graph on the touchscreen, while viewing analysis results on the other screen. You can create directed and undirected edges, move and delete vertices, set source and target vertices, and pan and zoom around larger graphs.

The app includes 27 graph-analysis algorithms, covering reachability, shortest paths, cycles, topological order, Euler trails, DAG paths and kernels, game-theory analyses, bipartite matching, spanning forests, core numbers, dominators, cuts and disjoint routes, and feedback sets. It also includes component analyses such as weak, strong, and unilateral components; loops; articulation vertices; bridges; and source and sink SCCs.

Results are visual, not just text. Component analyses can show both the original graph and a quotient view across the two screens. You can swap the result view to the touchscreen and explore it independently. Analyses stay active while you return to editing, and the app reports when an algorithm’s requirements aren’t met. DAG transformations can be previewed before you choose to apply them.

Digraph DS supports graphs with up to 200 vertices and 20,000 stored edges. Dense-graph rendering uses caching, clipping, and level of detail to keep interaction responsive; those display shortcuts don’t remove edges from the graph or its analyses. You can also generate complete or random graphs, save named projects to SD or a flashcart, and check runtime and memory statistics in the app.

The current app is v0.5.10. Digraph DS builds as a Nintendo DS ROM. Desktop frame-preview and Android library builds are available as development groundwork; a desktop window and installable Android app are still future work.

I’d love to hear what graph problems you’d explore on a DS, and what you’d like to see next.

So I'm trying to essentially mess around with Style Savvy to see if I can mod the Japanese version of some items into the English release, as there are some slight regional differences. However, like 1/4 of the files I'm seeing are .bin files for some reason? A person from around 7 years ago had this same problem, but it was never answered, and the account has since been deleted. From his findings, it looks like the .bin files are like... a mishmash of different file types? Currently I am using Tinke as well, even though I know it is depreciated currently. I am not too well-versed in decompiling nor am I well-versed in Romhacking or hacking in general, so any help I can get from anyone who knows more than me will be much-appreciated!!

Hi everyone, how's it going? Can someone help me with the Acekard?

I bought a DS Lite with an R4 Acekard and I'm trying to install Pokémon Black, but when I go to start the game, it gets stuck on the loading screen.

I’ve been working on Readmanna, a fork of ds-mangaman that turns the DSi into a portable reader for manga, comics, and books. The idea is to make it feel a little like carrying a tiny Kindle in your pocket.

The original ds-mangaman was a great starting point, but its workflow had some limits: processing PDFs could take a long time, and the finished book was bundled into a single ROM. With a book around 300 pages, starting up could take as long as 10 minutes.

Regardless ds-mangaman is a great! homebrew and im glad that the creator made it public.

Readmanna changes that workflow. Convert a PDF or a folder of page images on your computer, then copy the prepared book to your SD card. The reader app and your books are separate, so you keep one Readmanna ROM and can add or change books without rebuilding the app. The finished books are ready to open from the DSi’s book selector.

It also has seven zoom levels, so you can fit a whole page across both screens or zoom in to read smaller text. Rotate pages to read upright or sideways, then pan with the stylus or D-pad. There’s a page selector for jumping ahead, and Readmanna remembers your position, zoom, and rotation for each book.

Also you can go to any page you want by pressing B) showing a menu for going anywhere you want

Rendering is faster because page images are prepared on the computer before they reach the DSi. That lets the reader use prepared images at common zoom levels instead of doing all the resizing itself. There’s also a compact 256-color export option. Depending on the source and export settings, I’ve seen books shrink from around 300 MB to 80 MB.

PDF conversion happens on your computer; the finished books are what you read on the DSi. The project is open source, and I’d love to hear what people think or what features you’d like to see next:

Built with BlocksDS

I recently managed to extract both NTTX and NARC files from the rom of Yu-gi-oh nightmare troubadour but can't find any software to use them. Is there anything that I could use ?

Note: Those files contain data related to monster models and animations.

I’ve been working on expanding the Nintendo DS version of Age of Empires and wanted to start a thread to share my progress, discuss ideas, and get feedback from other players.

My coding experience is limited, but with some basic knowledge and help from Codex, I’ve been able to turn several ideas into working features. I’m running my builds in DeSmuME and in Delta on iOS.

Here’s what I’ve added so far:

• A fifth player on the Empire map.
• Custom maps, including the Hawaiian Islands and island maps designed for naval battles.
• AI improvements.
• Three ship types: scout, passenger, and battleship, with carrying capacities.
• Enemy intelligence: the ability to purchase information about an opponent’s finances.
• Expanded research options to support the new ships.

I’m currently working on adding a Viking civilization.

I’d love to hear what you think of the additions so far and what you’d like to see next. Any ideas for new civilizations, units, maps, or gameplay features? Feedback and suggestions are welcome!

Bonjour, je suis un jeune de 15 ans et je viens de moder ma console (n2ds old) ce matin et ai voulu continuer a jouer a pokémon Y, comme je n'arrivais à battre la ligue, je me suis demandé ''pourquoi pas augmenter le niveau de mes pokémons, DCP je les ai maxés avec PKSM depuis hombrew.

Je me suis give full objets (script avec PKSM) et maintenant ma console affiche ça a la fin du Panthéon, maintenant je suis bloqué et je ne peux plus continuer.

Il y a un moment déjà, ma console buggais beaucoup aussi (avant le hack) et je ne pouvais pas quitter la ligue Pokémon y du tout, a la fin d'un combat la console bloquait, se coupait et quittait le jeu, me laissant uniquement avec la dernière sauvegarde et ma déception. Si vous voulez plus d'infos et tout, demandez 😊

Merci
