Pretty cool! I'm no artist but it was a pretty good way to test the accuracy of my stylus on Azahar for Android

It appears the latest version of the .cia/.3dsx file is not uploaded to GitHub.
The QR code doesn't work either.

I completely forgot to attach the build file. Sorry about that.
I just attached it, and the QR code should be fixed now too.

Please give it a try!

Now this is an awesome App. I love drawing!

I've used the -also homebrew app Colors!- and loved it.

Will try this one asap.

Thanks a lot for sharing it!

The problem of extremely slow Save, Load, and Preview has been fixed!
Saving a 1024x1024 canvas, which used to take several minutes, has been reduced to a few second🏎

16x16 images don't work

Thanks for reporting the bug. I hadn't noticed it myself.

Honestly, it looks really weird. It doesn't reproduce on emulators like Citra.

I've created an issue on Github to identify and fix the cause. Once the official release with the fix is ready, I'll report it here in the thread too.

im an artist myself and hey its pretty good drawing app! absolutely love it , so i will draw more on this ! but it would be great if it will be transform , or just basic " move " layers in the future . And i made a quick draw to test this app :

When will it be O3DS compatible?

I really want to get it working for the Old3DS as soon as possible, but honestly, I only have a New3DS so I can't test it myself.

It should probably work as it is, so it would be a huge help if someone could test it for me. Just a heads up, it'll likely freeze on larger canvases because it'll probably run out of memory.

this is a really cool app. it's really motivating me to get back into drawing after sketching something with it last night!

I checked, images smaller than 33x33 don't load (crash).
Edit: The software also works on the old 3ds (except for images smaller than 33x33)

You can recruit the testers, tho.

Sorry for being MIA lately.
I finally squashed that bug where the app freezes on small canvases. I am planning to add a few more features and drop a new version soon, so stay tuned!

SimsCrafterZ · Apr 10, 2026

Will the small images look like this?

Yeah, that'll be possible. I'm adding a smooth zoom toggle to the settings screen in the next release.
