  • Universal converter for non-exclusive cards of video game
    Patent number: 5282621
    Abstract: A universal converter for non-exclusive cards of video game includes a first slot device for receiving a code-including video game card, a second slot device for receiving a general video game card, and an interconnecting device for coupling between the first slot device and the second slot device. The general video game card can not be played in a specific main machine because it lacks some secret code to turn on the main machine, while the code-including video game card is allowed to be played in the main machine. The universal converter for non-exclusive cards of video game receives both the code-including video game card and a general video game card enabling the general video game card to be played in the main machine.
