Square released a ported version by Tose in Japan for the PlayStation in 1999, which was later repackaged with a "Final Fantasy IV" port as "Final Fantasy Chronicles" (2001) for the North American market. A slightly enhanced "Chrono Trigger", again ported by Tose, was released for the Nintendo DS in North America and Japan in 2008, and PAL regions in 2009. The Nintendo DS version sold 790,000 copies by March 2009, after about a year of sales. "Chrono Trigger" has also been ported to i-mode, the Virtual Console, the PlayStation Network, iOS, Android, and Microsoft Windows.
