(Ab)using Wiinnertag to create a Discord rich presence for USB Loaders

The end result looks somewhat like this:

• Python 3.6 or higher (I might make Windows executables soon)
• A Wii and PC with an internet connection
• A correctly set up USB loader (more below)
• Last but certainly not least: A Wi-Fi hotspot on the PC that runs the application. More below.

Believe it or not, this is actually very (!1!11!!) important. Due to unknown reasons, the webhook sent by the Wii will fail to send to an internal IP address unless it's connected to a hotspot on the PC. If you like wikiHow (who doesn't?), check out this tutorial to assist you into setting one up.

Note: this program was tested using USB loader GX. Support for other loaders was made based on assumptions.

Contact me if you want to test other loaders so I can add them below.

For this loader, you should make sure to enable the "autoinit network" and "Wiinnertag" settings. It might ask you to create a config file; make a guess and pick either yes or no. It doesn't really matter.

This script creates a config file for USB loader GX on every boot (named Wiinnertag.xml). Place this file in SD:/apps/usbloadergx/ and you should be set. Make sure to refresh it once in a while; based on your router, the internal IP of your PC may change, breaking the program. To prevent this, set up a static IP address.
