HTML5 Games Scraping

I need a reliable scraper that can collect complete HTML5 arcade games—code, assets, and any associated metadata—directly from public websites. My goal is to gather a usable catalogue I can later adapt for my own arcade-style project.

Core needs
• Extract the full game package (HTML, JS, CSS, images, audio) for each title you target, keeping original folder structure intact.
• Capture key metadata in a CSV or JSON: game name, source URL, canvas size, and any licence or attribution text that appears alongside the download.
• Provide well-commented Python code (Scrapy or BeautifulSoup + Selenium if required) so I can rerun the crawl whenever I add new source sites.

Timeframe
This is urgent—I’d like to see a working proof-of-concept within the first day or two and the full scrape finished as soon as possible.

Hand-off
I should receive the dataset, the scraper scripts, and a short read-me explaining prerequisites and how to extend the crawl to new domains. If everything runs locally without manual tweaks, the job is done.
