SignaPic DSi is a tool to simplify operation to process any JPG image into Nintendo DSi Standard JPG image, with some additional features.

Features

  • Simplify the process to sign image for DSi.
  • JPG resolution optimizer (optimize all JPG image resolution to 72 DPI).
  • Auto detect System Region.
  • Auto directory detection (100NIN02, 101NIN02, etc).
  • Auto file-numbering (HNI_0001, HNI_0002, etc).
  • Auto proportional resize for non 4:3 JPG image.
  • Auto color detection for letterbox/pillarbox in Proportional resizer.
  • Auto generate image thumbnail.

Installation

There are 2 versions of SignaPic DSi. The only difference is the size, the Minified is half smaller than the Normal one. Works on Windows OS (x86 and x64).

Note: Minified version sometimes triggers a false alarm where Anti-virus misunderstands and detects this version as a virus, due to the fact that the structure of the tool is no longer neat (trimmed).​

Known issues

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)

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
