In general, console went on sale and it was never released to the foreign market, it was a purely Japanese product for the citizens of Japan. Actually vertical position was used only in some games, but specially for this a second joystick was designed. The second feature - users could play holding the console horizontally and vertically. Console has two amusing features - personal data input and the use of two joysticks. Despite the fact that the console was originally black-and-white, it was created as a competitor to the existing at that time Neo Geo Pocket and Game Boy Color. In his honor was named the first game for WonderSwan - Gunpei.
