Wait, I'm confused now. DSi enhanced cards will play but the normal DSi cards won't? Explain that to me. However, I do agree that Days won't be DSi
Two new types of cards, DSi Cards, and DSi Enhanced.
DSi Cards only work in a DSi system. (DSi Only)
DSi-Enhanced Cards can work in all types of DSes, but when used in a DSi, has additional DSi features (like use of the cameras).
