Abstract: A cartridge may be inserted into a cartridge insertion slot of a game apparatus in a first direction. The cartridge may include: a terminal placement region that includes four groups of terminals configured to electrically connect to terminals in the cartridge insertion slot of the game apparatus. Each group of terminals may include a first terminal that extends longitudinally in the first direction and two second terminals that extend longitudinally and are positioned sequentially in the first direction, the first terminal and the two second terminals being positioned sequentially in a second direction that is perpendicular to the first direction. Each group of terminals may be arranged sequentially in the second direction.
