Nokia file format conversion: NCC to NFB

NFB file format: (struct nfb_file)

struct nfb_string {
   int               nchars;
   short             chars[nchars]; /* Two byte Unicode (UCS-2) */
};

struct nfb_header {
   int               version; /* 3 */
   struct nfb_string firmware;
   struct nfb_string phone;
   int               nentries;
};

struct nfb_file_entry {
   int               type = 1;
   struct nfb_string path;
   int               nbytes;
   char              bytes[nbytes];
   time_t            stamp;
};

struct nfb_directory_entry {
   int               type = 2;
   struct nfb_string path;
};

struct nfb_file {
   struct nfb_header header;
   union {
      struct nfb_file_entry      file;
      struct nfb_directory_entry directory;
   } entries[header.nentries];
   int               crc32; /* zlib.crc32() */
};

Example usage of nfbfile.py:

   import nfbfile

   n = nfbfile.NfbFile('Nokia 6230 04-08-2004.nfb')
   image = n.read('\\FILES\\Graphics\\OrangeUK6230Wallpaper.jpg')
   file('OrangeWallpaper.jpg', 'w').write(image)
