no they are like....err...kinda like those cards they had for spectrobes, you place them over the screen, tap the holes in order, and unlock whatever the card is for, it comes with like 280 cards, which ranges from things to a few memory+s, to very powerful battlechips(a few G ranked ones i think like dragon and stuff) and other stuff, havent opened mine yet to be sure it works with the rom version.
EDIT: ROFL i feel like a noob for asking seeing as right after i asked it popped up on my normal rom site i use >_>, xD, noobness ftw.
