Fire Emblem is one of those legendary hard to find anime. It was released commercially in America on VHS in both subbed and dubbed versions (making that no-group subbed version a rip of the subbed VHS version, not a fansub). So a dual-audio release is technically possible. And in Japan, it was never re-released on DVD, but it was released on laserdisc, so one could probably capture half-decent video and Japanese audio. Probably won't ever happen.
