Aeon Genesis, ending its long reign as the sole entry in the Ys series to never see an English-language release.
Ys 5 debuted as a somewhat controversial game in 1995, arriving exclusively on the Super Famicom after a string of multiplatform releases. Ys 5 ditches the simplified enemy-ramming combat of earlier Ys games in favor of more traditional, Zelda-like fare, giving players more control over sword strikes and defensive maneuvers.
Series enthusiasts previously localized the PC Engine version of Ys 4: The Dawn of Ys and its Super Famicom counterpart Ys 4: Mask of the Sun, and many other entries in the series were officially translated and released in North America. Ys 5 was never officially localized and a revised edition, Ys 5 Expert, also remained exclusive to Japan.
A translation patch for Ys 5 is available at Aeon Genesis' website, and requires either an emulator or a Super NES flash cartridge to play. Falcom's most recent series entry, Ys: Memories of Celceta, was released last week for the PlayStation Vita in North America.
