I'm extremely confident that's real, based on that picture. (That's a rental "SNKG" cart, and I've never seen a bootleg in one of those. The serial sticker is also a good indication, as bootlegs simply don't have those either.) But you'd have to look on the inside to be sure. My real Puzzle Bobble cart is exactly like that one, except the sticker is on the other side of the label. My serial number is 5323, so yours is a lot higher.
