For the 20th anniversary of Final Fantasy, Square Enix remade Final Fantasy and Final Fantasy II for the PlayStation Portable. The games were released in Japan and North America in 2007, and in PAL territories in 2008. The PSP version features higher-resolution 2D graphics, full motion video sequences, a remixed soundtrack, and a new dungeon as well as the bonus dungeons from Dawn of Souls. The script is the same as in the Dawn of Souls version, aside from the new dungeon.
