Transfer the save file to your PC, and try renaming it to .png and see if it opens.

If it does NOT open, try this website: Savegames convertor and convert your file to the “Supercard One / Ninjapass / DSLinker (.sav)” format, and then try renaming to PNG.

* DLDI
* Saving & Loading to BMP
* Pencil and Brush tools
* Paint Bucket
* Blur tool
* Zooming — allows to draw an image 2x the size of the screen
* Undo/Redo
* Nice GUI

Things that it’s still missing which I had:
* Save & Load to PNG
* Save & Load to SRAM (for flashcart users, and slot-2 devices which have no DLDI)
* Slow paint fill — his just fills everything
* Nicer color picker — his makes you twiddle with R,G,B sliders

Give it a try!

(gfx shamelessly stolen from )

If you can’t wait, and need to get some drawings done ASAP, you can download a previous version.

UPDATE: It also seems I’ve defeated the long-standing issue of the ‘jumping lines’ once and for all!!! I need to do some more testing to confirm it, but it looks good so far!!

Only change from last version is I’m testing with the new alpha version of libfat. Currently loading is DISABLED as libfat does not support directory listing yet. If you want a fully functional version, please see this previous post.

I have tested saving on GBAMP and Supercard CF. Please, test it on your devices and let me know if saving works correctly. As I recieve reports, I will update the info below. Thanks.

Tested, working: GBAMP, Supercard CF
Tested, seems to create 0kb files? M3 SD
Untested, but should work on: M3 CF, Supercard SD, Neoflash MK2/3
Untested, may or may not work: Max Media Player/Dock, EFA2

NDS version
.DS.GBA version

And here are the two test images I made:

Apparently, a workaround is to launch it through moonshell. So if you find that you cannot read the information on the top screen, then try running my app from moonshell, instead of directly from your flash cart menu.

Draw version R10 is released! The new features are:

  • Saving to SRAM, flash-cart users can now save!
  • Loading saved .png from CF/SD adaptors
  • Loading saved image from SRAM (again, for flash cart users)

Now, I don’t have a working flash cart, so I would be grateful if you could test out the loading and saving to SRAM, and post the results into the comments here. The main limitation is that I can’t save larger than 64KB images to SRAM. This will be solved in the future (most likely by lowering the image quality, there are several optimizations I can make.)

Download R10 .zip

  • “Smudge” tool — will smear the colors around, can be used to create a ‘watercolor’ like effect
  • “Picker” tool — the standard ‘eyedropper’ tool, select a color from off of the canvas
  • Color picker enhancements — L button now exits the picker, also shows the current selected color in top right
  • Controls change — Change the current tool using the Left/Right buttons now.

Latest update

As always, I welcome feedback, and please send me your pictures as well!

(FYI: All the images I post are resized to 50%, which is how they are displayed on the DS’s screen. I usually then link them to the full-size png, which usually doesn’t look as smooth, but has the advantage of being twice the resolution of the display on the DS)

  • Bucket Tool – using the ‘slow fill’ method I talked about. It’s not 100% perfect yet
  • Eraser Tool – this needs some more work, if you erase slowly it does funny things
  • Better color picker – Looks more like a normal color picker, and I included a greyscale bar to easily pick whites/blacks/greys.

Again, I’d be thankful if people could test it out and let me know how it works. I welcome all feedback / bug reports / etc.

So I am providing a version which has been tested to work on SC:CF:
