GoNintendo has reported: "Final Fantasy IV is a big game no doubt, but it is coming on a big DS card as well. The card comes in at 1 gigabit, or 128 mb for those wondering. The extra space is needed for all the voice work in the game. Voice work wasn’t planned for the remake at the start, but obviously that changed once development got underway." Yikes! Time to get a bigger microSD. Good thing the CycloDS accomodates larger cards.
