I've seen a couple of requests on the site from a year, two years ago. One was an ambiguously-named collection at the top of this thread (http://forums.ffshrine.org/showthread.php?p=1172882) named "Yu-Gi-Oh," but the download expired.

This (http://www.youtube.com/view_play_list?p=E70683093C60C977&search_query=eternal+duelist) is the only thing I can find, but it's not complete and the music is a bit skippy. Anyone have better luck?
