In a game system including a wireless LAN AP instrument and a portable game device, the AP instrument transmits a beacon signal including a MAC address of the AP instrument and a network ID obtained by encoding an instruction code so that the network ID can be decoded using the MAC address. The portable game device decodes the network ID included in the received beacon signal using the MAC address, and executes control based on control data when authenticity determination data included in the decoded instruction code coincides with specific data and the present date is within a valid period indicated by valid period data.

A model object MOB (tree) having a plurality of part objects (branches) POBand POBeach of which has a projection shape is arranged in an object space. Each of the POBand POBhas a projecting portion formed on a display surface on which an image is drawn. The POBand POBare rotated so that the display surfaces thereof are directed toward a virtual camera VC. A Z texture for setting bump shapes on the display surfaces by pixel unit or forming a virtual projection shape on each of the display surfaces is mapped on the POBand POB. When the VC rotates about a Y-axis and an X-axis while being directed toward a column-shaped part object (trunk) COB, the POBand POBare rotated so that the display surfaces thereof are directed toward the VC.

A detection device detects positions at which a sword-shaped controller traverses first and second sensor planes, which are formed by first and second sensors, respectively, and positions of which are associated in a one-to-one manner to positions on a screen. A position on the screen, an amount of change in the position per unit time, an absolute value of the amount of change of the position, and an orientation of the sword-shaped controller with respect to the screen are obtained from input information from the detection device. At least one of a special-effect image, a sound effect, and a parameter that causes a change in the special-effect image is changed, based on one of the obtained position, amount of change in the position per unit time, absolute value of the amount of change in the position, and the orientation of the sword-shaped controller, so that a special effect is changed with respect to the operator of the sword-shaped controller.
