The WonderSwan was originally developed as a grayscale device by Koto Laboratory, the company founded by former Nintendo engineer Gunpei Yokoi (横井 軍平). It was followed the WonderSwan Color and the active matrix SwanCrystal. After being unable to fend off competition from Nintendo's Game Boy Advance, the WonderSwan line was discontinued in 2003. It remains Bandai's last and best-selling console to date.
