The ASCII keyboard controller was a controller made for the Nintendo GameCube in Japan. It is an immensely extended white or blue GameCube controller that features an alphanumeric keyboard in the middle of it that contains hiragana and Latin characters. All of the standard buttons that are present on a normal GameCube controller are also here. The start button, which is in the center of a standard GameCube controller, has been moved to the left side of the keyboard.
It was made exclusively for Phantasy Star Online Episode I & II.
