News / Weather channel downloads data packages from Nintendo servers via plain http connection.

Some examples:

http://weather.wapp.wii.com/1/076/short.bin http://weather.wapp.wii.com/1/076/forecast.bin http://news.wapp.wii.com/1/076/news.bin.08

Nowadays, it seems the news file has moved:

http://news.wapp.wii.com/v2/1/076/news.bin.00

...

http://news.wapp.wii.com/v2/1/076/news.bin.23

File structure:

$0000 - $003F: padding (00)
$0040 - $013F: rsa encrypted sha-1 signature of rest of the file
$0140 - $....: compressed data

Data compression method is still unknown. If you calculate entropy of the data, you will notice that it is definitely not encrypted. Probably it uses a modified version of propieritary Nintendo compression method described here: http://everything2.com/index.pl?node_id=1469892
