Final Fantasy IX: Digital Edition

PC & Mobile
At the time of release, the game was notable for its lack of a release for Microsoft Windows, which had been granted to both the previous titles Final Fantasy VII and Final Fantasy VIII; this marked the end of Squaresoft's support for the Microsoft Windows platform.

However, on January 1, 2016, Square Enix announced that Final Fantasy IX would be coming to Microsoft Windows, Android, and iOS, and that the game would feature high-definition graphics, achievements, an auto-save mode, and a high-speed mode. The Steam page went live on January 6, 2016, with an Early 2016 release date. A trailer was released on January 8, 2016, that provided samples of gameplay and cinematics. On January 21, 2016, the Steam store page for Final Fantasy IX was changed to "Coming soon", although "Early 2016" continued to be listed on the right-hand side; this was corrected and switched back the following day, January 22, 2016.

On February 9, 2016, Final Fantasy IX was released on iOS and Android, with the Android version being named Final Fantasy IX for Android. Final Fantasy IX was also released on Steam for Microsoft Windows on April 14, 2016.

On September 19, 2017, Final Fantasy IX was released on the PlayStation Store for the PlayStation 4, under the name Final Fantasy IX: Digital Edition, having been announced by Square Enix on the same day.
