@TheLegendofMario : my tool was inspired by the post he made (https://gbatemp.net/threads/how-to-...ndo-dsi-requires-dsi-and-a-windows-pc.497896/) :mthr:
MWandel : programmer of 'JHead' console tool to manipulate EXIF of JPG file
Nba_Yoh/MrNbaYoh : programmer of 'DSi JPEG Signature Tool' console tool to sign JPG file tobe readable by Nintendo DSi Camera Application

If you have already read the thread by @TheLegendofMario (the full link on "thank-list" above) then you know what exactly my tool's main job.

SignaPic DSi is a tool to simplify operation to process any JPG image into Nintendo DSi Standard JPG image, this tool is not just simplify the process, but also add some features :

  1. JPG resolution optimizer (optimize all JPG image resolution to 72 DPI)
  2. Auto detect System Region
  3. Auto directory detection (100NIN02, 101NIN02, etc...)
  4. Auto file-numbering (HNI_0001, HNI_0002, etc...)
  5. Auto proportional resize for non 4:3 JPG image
  6. Auto color detection for letterbox / pillarbox in Proportional resizer
  7. Auto generate image thumbnail
There's 2 version of SignaPic DSi. Actually the differences only in size, the Minified is half smaller than the Normal one, if you download using metered connection, this Minified version is enough to help save it, but sometimes, Anti-virus often misunderstands, and detects this version as a virus (false-positive). Because the structure of the tool is no longer "neat".

{known bugs}
  1. Not all JPG files are processed smoothly, sometime the result is not readable by Nintendo DSi Camera App. If this happen, please convert your JPG file(s) to a new JPG file(s) again using image converter (i have tested this using FormatFactory)
  2. Some image files downloaded from Facebook and Twitter (or maybe another social media) cannot be directly processed (it will result as glitched or even unreadable image), that you must convert them first to a new JPG file using image converter
Please tell me when you find another bugs.
If you will, for faster respond, you can mention me :)

{tutorial}
1. Run the application

2. Click "IMPORT" and choose the file you want to process (currently supported is JPG only)

3. After all files listed, click "PROCEED"

4. On PROCEED EXPORT window, choose the option you want (right click an option to show its description)
For example here, i want to process my JPG images to my SD Card on drive G: (see i selected "Auto | Select SD Card Drive :", and choose drive G), with JPG Quality 80%, Optimizes resolution (DPI), System Region "Auto Detect", Proportional sized with auto color and 5 points of color threshold

5. After setting up everything, click "EXPORT", wait until the process finished

6. And, if you're using "Auto" mode, all process like finding latest 1xxNIN02 folder, deleting "pit.bin" file, file numbering will be done by the tool

7. Finally, pull off your SD Card, then put it on your Nintendo DSi, open up SD Card option on Camera app


{suggestion}
  1. Leave "JPG Quality" to 80 for best result
  2. Leave "auto-repair" and "Optimize DPI" checked
  3. Convert your JPG into new JPG before process it with this tool
  4. Don't process too many files at once
  5. Put on your SD Card first, before running the tool if you're using Auto mode

depend on how many number you put in "color threshold" , between 1 and 16 :lol:

okay let's see, theres 3 thumbnails with question marks, it tell us that those images format was recognized by Nintendo DSi, but it's not readable (idk how to explain this hmmm). I put 105 processed images here, but only 92 are detected :unsure:

Hi! I've used this program to convert some images... but they won't show on the DSi Menu (hiyaCFW). Might it have something to do with the DSi Camera app? I can't go past the tutorial because my cameras seems to be broken, but I still wanna use those pics at the top screen :/

They need to have the star sticker iirc, they might need to be on your NAND (or SDNAND in this case) as well. A post-tutorial Camera save file might work, I dunno though

Yup, I've tried searching for a DSi Camera savefile but no luck yet... thanks about the star sticker info, didn't knew about that :P

Tried doing the DSi Camera tutorial on melonDS but you can't do it there either, so no idea where to get it.

I can send you a fresh one in a bit. Hopefully it has no personal information or is tied to my console...
