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 here, and code used by RiiConnect24 to download news data and generate files is available here.

-File structure:
-<pre>
-$0000 - $003F: padding (00)
-$0040 - $013F: rsa encrypted sha-1 signature of rest of the file
-$0140 - $0143: header
-$0144 - .....: compressed data
-</pre>
-The compression is very simple:
-# Read one byte
-# For each bit of the byte, msb-to-lsb,
-#* if 0, copy one byte to the output
-#* if 1, read 16 bits msb first in v, copy n bytes at offset m from the end of the output, n=3+(v>>12), m=v & fff
-Quick and very dirty C code:
-<source lang="c">
-  i = 0x144;
-  j = 0;
-  while(i < size) {
-    int k;
-    int v = data[i++];
-    for(k=0; k<8; k++)
-      if(!(v & (1 << (7-k)))) {
-        result_data[j++] = data[i++];
-      } else {
-        int vv = (data[i] << 8) | data[i+1];
-        int nb = 3+(vv >> 12);
-        int off = (vv & 0xfff);
-        int l;
-        i+=2;
-        for(l=0; l<nb; l++) {
-          result_data[j] = result_data[j-off-1];
-          j++;
-        }
-      }
-  }
