Welcome to GoW, MysBibi!
You would put the files in the URU CC folders. Specifically:
- Put the dat files in the dat subdirectory
- Put the Python files in the Python subdirectory
- Put the sdl files in the sdl subdirectory
Then start ULM, and on the Personal ages tab, drag Ahra Pahts over to the right side. Exit ULM, then start URU. You'll find a new book on your Relto shelf for Ahra Pahts.
Good luck!
