Hey players of Rockman Xover, there's a new special edition Battle Memory to grab, and this time you don't even need to buy a product to get it! Just use the above code, and you can get Tablet Man's Battle Memory. If you'll recall, Tablet Man is one of the runner up winners in Xover's boss character contest. To redeem the card, press the "other settings" button (under the E tank button). Then press the button for special codes (top left button). You can enter the above 16 digit code to grab the card. This guide explains the process visually.
Thanks for the tip, Django!
