SYSTEM FOR TESTING GAME MACHINE

摘要

PROBLEM TO BE SOLVED: To record history of game states accurately without grouping state signals in testing game machines with a plurality of game states changing simultaneously. SOLUTION: A system for testing game machines comprises a game machine with which games are actually played and a testing machine connected to the game machine. An output port to output state signals showing game states is provided on the game machine. The testing machine is equipped with an input port (P) allowing constant input of all kinds of state signals output from the game machine, and it acquires all kinds of state signals to be input into P and records them in chronological order if one state signal to be input into P changes. An I/F board provided between the output port and P is equipped with a first latch circuit allowing temporary storage of state signals output from the output port by each kind and a second latch circuit which outputs the state signals stored in the first latch circuit to the testing machine at a prescribed timing to output signals and keeps the level of the state signals until the next timing to output signals.
