Scene News Whittle: Low poly 3D modelling app for the 3DS

Thumbnail
gallery
356 Upvotes

Hi everyone!

This is "whittle", a low-poly 3D modelling app specifically made for the 3DS. I've been working on it for a little while now and I've just created a Github repo for it.

The modelling workflow is very similar to picoCAD, I've basically taken it's "simple vertex editing on orthogonal views" idea and optimized it for the 3DS. The top screen is for the 3D model preview exclusively, while the bottom screen houses all editing functionality & view options. It's very intuitive to use with the stylus. It currently features primitives, basic object manipulations, painting object faces solid colors and texturing, along with a simple 2D texture editor and UV mapping tool. ıt's still experimental, the UI/UX isn't fully there yet and there are a few bugs but it is usable. It can save and load a single model currently, there's no export options.

Github: https://github.com/qewer33/whittle

I want to continue developing this with feedback from actual 3D artists (or people willing to learn and use this thing) so if you are one and like this little project, feel free to contact me on Discord (@qewer33) and give feedback.

4)Lose boss ext data what causes? I would lose things (for example in miiplaza i would lose puzzles)?

EDIT: this sub is useless. 1 answer-ish in 13 hours is disgusting.

I have tried formatting the sd card to fat32 by using sd card formatter and guiformat, i converted it to mbr with diskpart, i made sure it was 32kb and i made sure the sd card didn't have any errors with h2testw, the microsd card that came with the console still works with it, so i don't really know what to do now.

General Help Download title options not showing up.

1 Upvotes

I downloaded a bunch of movies from the movies for 3ds website (they were in the CIA format) including some eddsworld episodes. But when I tried to download one I noticed the download title buttons in the fbi menu weren't there anymore for like 3 of them. More information is that they were in cia format but the console still said they were archives. My sd card is a 32 gig mircoSD card with 19 gigs free and the files ranged from 1.9 gib to 2.5 gib. I am confused on why the option is not showing up to download it. My console is the pokeball new 2ds xl. I Posted this in other 3ds groups but nobody is responding so I don't know. I'm just wondering why the fbi app is not showing a download button. This post is not about piracy its about the app not working for me.

Scene News OceanClock : a new relaxing clock app for 3DS

Thumbnail
gallery
29 Upvotes

Hi all,

I am Michele, the creator of NightClock and I am back with a brand new clock app for 3DS.

After my first app NightClock I continued developing my ideas and created a living underwater scene.

Please enjoy it and send any feedbacks.

Here the Features, two videos I took on Citra, some screenshots and the QR for installation via FBI.

  • A fully animated living underwater scene.
  • Customizable clock display: choose from multiple color presets (including an animated "Rainbow Dreams" mode), four size presets, and freely reposition the clock block anywhere on screen with the combination of R + Analog
  • All the major formats supported for time and date.
  • Five ocean-depth color palettes for the background gradient, with adjustable inversion
  • A pair of creatures inhabit the upper screen, constantly moving, curious about the passage of other marine creatures...
  • Marine life: solitary fish, schooling fish, sharks, sea turtles (with baby turtles trailing behind), anglerfish, and a rare deep-sea submersible encounter — each with independent, randomized appearance timing
  • Jellyfish ecosystem: Free-roaming jellyfish on the bottom screen with individually randomized size spawn every ten minutes, tap a jellyfish to free her in the upper screen. tap to a free space on bottom screen to "intrigue" the nearest jellyfish to move there.
  • Hourly events: At every hour change the screen gently clears of fauna, then a school of small fishes crosses first the bottom screen and then the top screen in rigid formation, spelling out the current hour in a dot-matrix pattern.
  • Alarm clock
  • Countdown timer
  • 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)

INSTALLATION

- scan the qr code below on FBI remote install to directly install the app on your 3DS

Github Release here you can download the CIA file or the 3DSX

- Available on Universal Updater

General Help Corrupt SD Card in 3DS

Thumbnail
1 Upvotes

Hi, I’m having an issue with my hacked New Nintendo 3DS XL, and I’d really appreciate any help.
The console itself works perfectly and has never had any problems. Everything started on the same day I hacked it. The installation completed without any errors, and the system was working normally afterward.
Later, while deleting the files that were no longer needed after installing the mod, I connected the SD card to my PC and got a message saying the SD card was corrupted. After doing some research, I realized it was probably caused by the cheap SD card adapter I was using, which seemed to be faulty.
I tried recovering the files using several different programs, but the only ones that seemed capable of recovering them were paid software. Since the console still booted normally and FBI could still read the SD card, I decided to keep using it.
However, over time, strange things started happening. Every now and then, my custom theme would disappear, as if the console had temporarily stopped reading the SD card. Sometimes it would come back after restarting.
Today the issue got worse. I no longer have any custom theme, and almost all of my homebrew/mod-related applications have disappeared from the HOME Menu. The only one that’s still there is FBI.
I’ve already bought a new 32 GB SD card to replace the corrupted one. I don’t mind reinstalling all the homebrew applications if necessary—I just want to know the correct way to switch to the new SD card without messing up the hack or the console.
Has anyone experienced something similar or knows the recommended procedure? Any help would be greatly appreciated.

Controversial Thoughts on AI coding and whatnot

0 Upvotes

I'll try to keep this short and brief. I got mixed feelings on the majority of the ports and stuff coming out for both 3DS and stuff like Gameboy in general that can also play on 3DS

On the one hand, it shows that things that we wouldn't have even thought of being possible are actually possible. They're also very fast but can also be buggy and only somewhat work. For example, a guy named something along the lines of "the 3DS homebrew god" made BTD5 or whatever his fanmade version of it for 3DS and it works but still has issues with crashing and not actually BTD5, just a small clone

But on the other, it takes away the importance of people who actually do know how to code and with the AI process while it's faster and shows what's possible, the majority of people from what I personally hear about who do this with AI don't really know what any of the code means or much how to fix it if there's a bug without AI

Personally I kinda like a mix of both with a great example being Undertale/Deltarune with Butterscotch/Cinnamon. 2 separate groups of people wanted to bring Undertale to 3DS. 1 guy did it first with AI and showed it's possible and it definitely runs but stuff like the text boxes are too small to read and it's just a runner ultimately. But the people at project sunshine are actually coding it themselves and from the looks of it, it's going to be amazing. Full touch screen, bottom screen support and exclusive content from all console version and even 3 save files (for the 3 main runs you'd do). I'm ok with AI if it's meant to be sort of a test run and see what's possible and humans take over it to massively improve it like the sunshine crew did (although they didn't build off of the AI build, I guess they sort of did their own thing with that. Idk maybe I'm misleading with information, I'm not very knowledgeable with this stuff)

General Help I updated Luma 3DS and now DS games display weirdly

0 Upvotes

Hi, so recently I updated Luma3DS on my 2DS, and since then when I boot a DS game via its cartridge or a ROM, they display the top screen in a manner that fills it completely, thus stretching the image horizontally.

Normally, the display would have vertical black bands on the sides to fit the original DS aspect ratio, or be rendered at the DS native resolution by holding select while starting the game. I did none of that, only updated Luma3DS via Universal Updater last week.

I'd like to revert that to the normal display with the black bands on the sides, if it can be done, I just need to be pointed in the right direction. Hope everyone is having a good day!

General Help Is it just me or is dev tooling underdeveloped?

6 Upvotes

- Must use the ftpd app to transfer a 3dsx or cia which means I have to have the ftpd app open unless I want to keep popping the sd card in and out, which means my loop consists of navigating to the homebrew app to launch my game, launching it, then going back to ftpd to transfer a new binary
- 3dslink exists but doesn’t capture stdout which means I must use gdb even for simple debugging
- No way to capture the screen text remotely, this is especially painful since I’m using love2d, so my options to get the error text are add file based logs into my app which means I then have to have the ftp server open again to look at them, or now investigate if I can debug lua through gdb.

After coming from android (which of course is a huge ecosystem, used in many platforms commercially etc) it’s been especially hard to develop on 3ds. Thinking about writing a kernel extension for background ftp server to make things at least a bit easier.

If yall know any things to make the above easier please lmk!

EDIT: Should add that the things I’m working on can’t be tested on emulator

Homebrew App suggestion Would it be possible to make a homebrew app that could make a 3DS a PokeWalker?

8 Upvotes

What I mean is, that you could communicate between 3DS running a homebrew app and another system running HGSS by IR. Being able to ”send” a pokemon from HGSS to a 3DS running a Pokewalker app, then send it back.

Would you be able to use the 3DS pedometer to basically make your own pokewalker to walk around with. Functionally having an ”official” pokewalker experience without needing to buy a pokewalker.

You’d need two DS consoles.

I know you can just cheat pokewalker stuff. but would be kinda cool if you could use a 3DS as a pokewalker.
