The first three games in the series, originally released only in Japan and in Japanese between 2001 and 2004 for the Game Boy Advance platform, have been ported to the Nintendo DS as well as localized into English and other languages. The series has been developed for the DS from the ground up starting in the fourth game. The DS remakes and games in the series take advantage of the DS features, including the microphone and touchscreen. The art director for the series is Tatsuro Iwamoto, with Kazuya Nuri and Kumiko Suekane doing other illustrations.
