Final Fantasy IV[a] is a 2007 role-playing video game developed by Matrix Software and published by Square Enix for the Nintendo DS.

It was released as part of the Final Fantasy series 20th anniversary celebrations on December 20, 2007 in Japan, on July 22, 2008 in North America, and on September 5 in Europe.

The game was well received by critics and fans alike; it was praised for being sufficiently faithful to the original while expanding on many gameplay and story elements.

[4] Final Fantasy IV is a turn-based role-playing video game retains the original Active Time Battle System from the initial Super Nintendo release.

The system allows for certain character-only abilities to be transferred to other characters who did not have them in the original and previous re-releases of Final Fantasy IV.

This includes individual abilities that are ordinarily contained in a group (e.g. "Curaga" can be added directly to Rosa's command list, rather than only being accessible through the White Magic sub-list).

Their function is to increase the power of Rydia's personal Eidolon, Whyt (ポーチカ, Pōchika, Pochika in the Japanese version), who takes her place in the battle line-up, and acts under computer control according to abilities assigned to him by the player.

The original storyline of Final Fantasy IV is retained, and some of the previously missing script has been worked into the DS version in the form of flashbacks, including Golbez becoming Zemus's pawn and the childhoods of Cecil, Kain, and Rosa.

[11] Square Enix held a casting for a vocalist to sing a rendition of Final Fantasy IV's "Theme of Love" composed by Nobuo Uematsu.

[12] Megumi Ida was selected from approximately 800 applicants to perform the song[13] "Tsuki no Akari" (月の明り, literally "moonlight").

[28] Writing for TechRadar, Christian de Looper and Emma Boyle called the remake one of the best Nintendo DS games they played.
