As demonstrated during E3, users who have Phantasy Star Online Episode I & II for the GameCube can download games to their Game Boy Advance. This feature, called the "N-Port," does not require a cartridge to play the games. Four games will be available, including Nights: Score Attack, Puyo Pop, Chao's Petit Garden, and Chu Chu Rocket. Both Nights and Puyo Pop were shown at the Sega booth during E3.
Phantasy Star Online Episode I & II for the GameCube is scheduled for an August 8 release in Japan.
