Project64/NagScreenBypassScript

The registry key generator script

Script requires Python 3. Does not need to be running on Windows. You do need to determine your machine ID.

Script for grabbing support info blob (as another way to get machine ID)

This script does need to be run on Windows or in Wine, as it grabs the information from Project64's registry key.
