My best advice is use 'Waybackmachine' look for old UK dbz fansites. I used
http://www.UKdb.net/ from back in 2002 before I ran the site. Also promos I have saved from YouTube from years ago.
Also on a side note Ultimate Battle 22 and Final Bout were released on PSOne on October 11th 2002 for £19.99.
