Abstract: When another information processing apparatus issues a request for participation of another player in multi-person play based on communication, a processor of a game device allows a state that another player has not participated in multi-person play to continue while a game program is being executed and it allows participation of another player in multi-person play when transition to a scene where execution of the game program with an emulator is started is made. The processor of the game device proceeds with multi-person play of the game program with the emulator based on communication between information processing apparatuses of players who participate in multi-person play, and temporarily suspends a game when an instruction to quit the game is given during multi-person play or when a request to quit the game is given from another player based on communication during multi-person play.

Abstract: There is provided, as hard ware, a device having a sensor deriving information obtained by driving a driving including at least the tire which is assembled with the wheel and is inflated at a given internal pressure under the comparable condition to that in an actual driving. Information output from the sensor of the hardware is input to software simulating a running state of a vehicle, and information indicating the behavior characteristics of the entire vehicle is derived from the software while at least a part of the driving information output by processing of the software is fed back to the hardware to control the driving condition of the driving part of the vehicle depending on the behavior of the vehicle. As compared with an actual vehicle traveling test, an actual frame traveling test, and a full computer simulation, a simulation system and an apparatus of a vehicle capable of easily obtaining information about the traveling behavior of the vehicle at a lower cost can be provided.
