The official website for Delta Emulator as per the subreddit is http://deltaemulator.com/. However, on certain country filters, a third-party website that 'seems official' appears in the top results, often ranked higher than the official site.
Although the website itself does not seem to be doing anything malicious for now (it's providing unofficial tutorials and downloads), the official website should take priority in the search results ranking, and the unofficial website ranked lower.
