The Oath in Felghana was first released in Japan for
Windows on June 30, 2005; an unrelated remaster of the original game for the
PlayStation 2 was released by
Taito months prior. It later received a port for the PlayStation Portable in Japan on April 22, 2010, with an English release by
Xseed Games on November 2. In order to help offset localization costs, XSEED licensed and paid for the use of a
fan translation that had been produced previously for the PC version. Xseed later added the localization to the Windows version, releasing it on March 19, 2012. This version is the same as the original Japanese PC release, but added achievements and leaderboards. The English voice acting was later added to the Windows version via a free update in February 2020, along with the ability to change the soundtrack to the
PC-88 or
X68000 version. A remaster,
Ys Memoire: The Oath in Felghana, was released in Japan for the
Nintendo Switch on April 27, 2023. It features voiced dialogue for Adol, higher-quality textures and character illustrations. It was released on May 23 for
PlayStation 4 and
PlayStation 5.
Memoire was released internationally on January 7, 2025. The soundtrack from
Ys III: Wanderers from Ys was re-arranged for this game by Yukihiro Jindo. The full 2-CD soundtrack,
Ys - The Oath in Felghana - Original Sound Track, was released in 2005. Released at the same time was
Ys - The Oath in Felghana - Super Arrange Version, a disc with 10 additional
Oath in Felghana arrangements. The
Original Sound Track and
Super Arrange Version were also released together in a package known as the
Ys - The Oath in Felghana - Perfect Collection.
Ys: The Oath in Felghana Musical Selections is a collection of 23 songs from the game that Xseed Games released with the Premium Edition of the North American release of the PSP port of the game. ==Reception==
