tikdecrypt is a program that will decrypt a Wii content file using a ticket file and the associated content index.

nus_download.sh is a bash script that will download and decrypt a title from NUS using the above 2 tools.

bindecrypt is a program that will decrypt a Wii SD card DLC backup file, provided the console-specific keys.

Building requires a GCC or Clang compiler.

• On Windows, use MSYS2 MINGW64. Visual Studio / MSVC is not supported.
• On macOS, install the Xcode Command Line Tools.
• On Linux / WSL, install the development package for your distro.
  • Debian / Ubuntu: build-essential

cc tmdparse.c -o tmdparse
cc tikdecrypt.c crypto/aes.c crypto/sha1.c -o tikdecrypt
cc bindecrypt.c crypto/aes.c crypto/sha1.c -o bindecrypt

...or build_all.sh.

(This is required before using nus_download.sh)
