The '''News channel''' download data packages from Nintendo servers via plain http connection.
The '''News Channel''' downloads data packages from Nintendo servers via plain HTTP connection. The official servers for the News Channel were discontinued on June 28, 2013; however, [[RiiConnect24]] has since restored its functionality.
The data files are RSA-2048-SHA1 signed, and the LZ10 compressed content begins at 0x140. A Kaitai file documenting the file structure can be found [https://github.com/RiiConnect24/Kaitai-Files/blob/master/Kaitais/news_file.ksy here], and code used by RiiConnect24 to download news data and generate files is available [https://github.com/RiiConnect24/File-Maker/tree/master/Channels/News_Channel here].
