That is the website. The OFFICIAL WEBSITE!! From the little Japanese I know it is a 20th remaster. (I think) After introducing the time line of everything. It says Dueling spirit. If I get this right it is mostly focused on Yugi and Kaiba.

Watch the video it is the top button. The website is in Japanese. I kinda have a jest of the video. Have any questions I will try to answer them. If it involves the video please tell me what part your question is.
