If you were to describe the VM System as a memory card, you'd be right......sort of.  It's pretty obvious just by looking at it that this is no ordinary memory card.  In the above image, you see two VM Systems being linked together.  There is a simple reason:  there swapping info.  unlike any of today's memory systems,  since the VMS is a system all by itself, the info on the card is always ready and the LCD screen and gamepad style controls allow easy memory management.  You might not even have to wait for the Dreamscape to access the memory card because the card does all the work.  It can also be used to coincide with the actual gameplay of a game on the Dreamscape.  Through the LCD screen you can set up secret moves or combos without your adversary seeing them (this would be perfect for football games).
