Abstract
A portable game apparatus includes a housing. This housing is provided with an LCD and an insertion hole. A cartridge incorporating a program ROM is inserted in the insertion hole. A CPU in the housing processes a game program to display game scenes on the LCD. The cartridge further incorporates an acceleration sensor. The acceleration sensor detects a movement and tilt of the housing. When the housing is positioned at an angle easy to play, if an operation key is operated, neutral position data is stored to an internal RAM. During game play, an output of the acceleration sensor is corrected by the neutral position data so that the CPU controls game scene display according to a corrected output of the acceleration sensor.
