Animation
There are two separate OVA anime series of Ys, with the first spanning seven episodes and covering the events of the first game, and the second spanning four episodes and loosely covering the events of the second game. The first anime expands on the relatively thin storyline of Ys I including a retelling of the prologue, previously only told in text in the original Japanese manuals.
Both series were released on DVD in English by Media Blasters' anime label "AnimeWorks". They can be purchased separately, or in a three-disc box set, entitled Ys Legacy. The dubbed/audio tracks have changes to some character names ("Dark Fact" becoming "Dark Factor", "Adol" becoming "Adle", and "Lilia" becoming "Lillian," for instance). Pronunciations of various names are inconsistent, sometimes within the same scene.
Included on one of the discs is what appears to be a preview for an anime based around Ys IV. This was created by Falcom as a "pitch" trailer to shop around to various animation studios, to see if anyone was interested in producing the series. They had no takers, however, so this trailer is all that exists of the rumored Ys IV anime.
