Wii U:Wupclient

Wupclient is a python tool used to connect to wupserver. It was originally part of smealum's iosuhax.

Setup

What you need

• The latest release of Python.
• The wupclient.py (Right-Click → Save As... → Save the file to a directory on your PC).

Instructions

1. Install Python.
2. Replace the IP Address in line 30 with the IP Address of your Wii U. Do not change the Port.
3. Open a Terminal or Command Prompt in the same directory as the wupclient.py.
4. Run python -i wupclient.py (On Windows: py -3 -i wupclient.py) to start wupclient in interactive mode.
   Several hexadecimal numbers should be printed to the Terminal on a successful connection.

You can now enter commands in the Terminal.
