This tool is the Java version of the popular ndstool by Rafael Vuijk, Dave Murphy and Alexei Karpenko
of the devkitPro team (https://github.com/devkitPro/ndstool).
It is based upon Martin Korth's DS specifications, which you can find in the original HTML version at
http://problemkaputt.de/gbatek.htm#ndsreference, or in a Markdown version at
https://mgba-emu.github.io/gbatek/#ndsreference.
This tool was developed as a library rather than a standalone tool, that's why the provided command line
utility is very basic, allowing for full extraction or full build to/from a directory (in contrast,
ndstool provides a rich set of command for single file extraction or insertion).
For extracting a ROM, suppose foo.nds to the foo_extracted directory, launch the JAR by passing the
following arguments:
java -jar jNdstool-1.0.jar -x foo.nds -d foo_extractedFor building a ROM foo.nds from the foo_extracted directory, launch the JAR by passing the following
arguments:
java -jar jNdstool-1.0.jar -c foo.nds -d foo_extracted
