Revelation: Dynasty Project IV
By Jeremy LaCroix, 2002

To play this game, you only need two free memory cards at any one
time.  Insert the first game card into Slot 1, and the anime card
into slot 2. You will only need the second game card, when the game
tells you to load it. Refer to the instructions given then, as it
is very different from how the card change system was intended.
