KH:CoM help (I would have posted in the general help thread, but that hasn't been touched in ages.)

I'm currently replaying KH:CoM(GBA version) after a long time and I'm on Destiny Islands (12th floor) and I just need 1 more map card to move on with the story (any map card with value 9).
Unfortunately, whenever I defeat enemies, they don't drop any cards or anything at all, for that matter(except experience,of course). The most I got within one hour was one enemy card from Barrel Spiders and one "0 value" map card and a premium bonus, if that counts.
I've gone to Traverse Town, Neverland and Hollow Bastion other than Destiny Islands and no one dropped anything besides those two cards(which I got in Destiny Islands).
Suggestions?

Use the 0 card, it counts as any other value ^^
