Wii U things

Things I made (or found?) when playing around with the Wii U

FST format layout

• wiiu_cdndownload.py - download titles from Nintendo CDN, including cetk (ticket) for system titles/game updates/etc
• wiiu_decrypt.py - decrypt titles from Nintendo CDN; requires Wii U Common Key, plus given encrypted titlekey if there is no cetk file
• wiiu_extract.py - extract contents from titles
  • --dump-info - print lots more info
  • --full-paths - show full paths in output
  • --no-extract - don't extract files, only show info
  • --all - show all files, including those with 0x80 bitmask in type (which probably means deleted file). only useful for title updates.
