I am having trouble with the Wonderswan and NeoGeoPocket emulators

i tried several bios, I tried several roms and a nothing

before you judge me

must say the games I am trying here used to work no problem! (ROckman Battle and Puyo Puyo Tsu/2) but suddenly now it is giving me problems

it just no longer works for some reason

help?…

It's been a while since I played with this console because the r4 isn't working, but I recently had the idea to try and download games on it if I could make it work again.

The DSi is reading other games, and the logo of the r4 appears, however when I try to play it shows the message "no card". If my r4 is dead, is there a way to know using a PC ?

I’ve recently bought my GF a Ndsi Xl for around 50$ and painfully managed to install unlaunch and hiyacfw using a laptop running winxp, a 3ds, and a really slow tablet disguised as laptop.

However, I’d really like her to experience it as if it was brand new(or almost there, considering the scratches lol)

So I was pondering if it’d be ok if I clicked this button, or if it’d brick/unsettle the jailbreak and etc

Because we live in the best time line for gaming... I'm porting Starcraft to 3DS. Test build to check FPS and TPS runs just fine and terran vs terran with AI playing works. So, the first 5% are done, now the rest of 95% have to be done.

Help, I’m asking far and wide, this is my first time modding a DSI

I really want to make a Pokémon fan game completely from 0, but I have absolutely no idea how to program it. Is it very difficult?

I'm completely new to modding, and recently looked at a guide on how to use a USB bluetooth dongle to add bluetooth connectivity to a DS Lite. The parts arrive this week, so I'm not backing out, though I'm lost on one thing.

The negative pin on the USB dongle, where exactly does that connect to? I'm fairly certain the two dark dots on the right image are brown, but the negative pin on the USB dongle appears black. Does this black connection just go into GRND on the topside of the PCB?

Tried reaching out to the original modded with no response, so... I'm a bit lost

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

- every other cutscenes

- you can see through some walls

- 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.

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.

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!!

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:
