I believe that you can find the torrents for Wild Arms: Twilight Venom, at SuprNova. It says that they are subbed by Anime-Sweden, however, I think that group just ripped them off the DVDs. From what the torrent name says, they are in japanese/english to my knowledge. Here is the link for 1-12 and here's the link for 13-22. Hope I could help.
