Abstract: A game system including a plurality of mobile game apparatuses, and a mobile game apparatus that can communicate with another game apparatus that exists within a communicable range by use of a radio communications unit. When a communicated state is established, exchanging conditions for exchanging game data are received and transmitted, and in a case the exchange conditions are coincident with each other, the game data are exchanged.

Abstract: A wireless communication game system includes a plurality of mobile game apparatuses, which function as a parent device or a child device and are capable of making a communication with each other, and broadcasts from the parent device a parent device packet including a parent device PID, a user name UserName, a game name GameName, an OC flag, an E slot, a U slot, and a payload. All the parent device packets are received from the parent device existing within a communicationable range of a user's own apparatus, and the user's own apparatus creates a parent device list, and displays the parent device list on an LCD. Therefore, a user or a player of his own apparatus looks at the game name of the parent device list, for example, and operates a cross key included in an operation key so as to select one desired parent device.

Abstract: In a game system of the present invention illustrative embodiments, a slave machine a process of lengthening a frame cycle at times k1 and k2 by a time period of j1 and a time period of j2, respectively, thereby establishing synchronization with a master machine. Also, the master machine carries out a process of lengthening the frame cycle thereof by a time period of i at time h1 to deliberately cause the frame cycle to tend to be slower than the frame cycle of the slave machine, thereby causing the slave machine to adjust the frame cycle thereof so as to be lengthened by a time period of j3 at time k3.

Abstract: According to a game system and a game apparatus of the present invention, when other game apparatus or a group to which a plurality of game apparatuses belong are present in a range where wireless communication by the game apparatus operated by a player is available, the other game apparatus and the makeup of the group are notified to the player. Thus, the player can form a group of desired game apparatuses by determining a group to enter in consideration of the displayed group information, and execute a multiplayer game using wireless communication.

Abstract: A game system includes a plurality of mobile game apparatuses, and a mobile game apparatus can communicate with another game apparatus that exists within a communicationable range by use of a radio communication unit. When a communicated state is established, exchanging conditions for exchanging both of game data are received and transmitted with each other, and in a case the exchange conditions are coincident with each other, the game data are exchanged.

Abstract: Wireless communication game system includes a plurality of mobile game apparatuses that are capable of making a wireless communication with each other, and function as a parent device or a child device. The parent device broadcasts a parent device packet in a first time slot, and receives a child device packet in a second time slot. The child device receives the parent device packet in the first time slot, and transmits the child device packet toward the parent device in the second time slot. In a U slot field of the parent device packet, the number of child devices CID, which is connected (or was connected), is included. In the child device, when detected that a communication is disconnected from the parent device, it is attempted to receive the parent device packet broadcast from the parent device. In addition, when the child number CID of a user's apparatus exists in a position of the user's apparatus of a U slot of the parent device packet, a restoring is successful.
