Download and archive files from site

I'm really into computer games on cassettes. There is a really good resource for this and I want to download every bit of information they have and use it for my own personal use.

This is the site: https://www.brutaldeluxe.fr/projects/cassettes/

What I'm looking for someone to do is download everything and put it in a dropbox folder. For the content of each page I want it saved as a .txt file and I want the the images, .wav file, and manual scans in a folder named for the game name in a folder of the publisher.
