Abstract
When users simultaneously play the same game with interconnected game machines, processing delays would conventionally cause inconsistencies in game content between different game machines. To solve this problem, the game machines are not synchronized with one another, but each game machine outputs operation key status data representing the state of a set of number of operation controls to the other game machines in accordance with predetermined data communication timing. A received FIFO data buffer in each game machine, sequentially stores operation key status data received from the other game machines. Only valid operation control status data is transferred to an operation data buffer for use in game processing. Inconsistencies in game content between different game machines are prevented through software-based synchronization which does not require hardware-based synchronization.
