Libellen by LiraNuna is a sprite handling library for the Nintendo DS, based on libNDS.
Release notes:
The impossible happened! I actually took some time to clean up and resolve the libellen-libnds collision problems, while also transforming libellen to the traditional library.a file. I also added very primitive background handler – it works, but don’t count on it.
Please remember that the source code and library (and everything inside the zip archive) is released under the terms of the WTFPL.
