Ok, I have a ds lite w/ m3 simply ds, but what I want to know are the difference between, the terms: Supercard, super key, passme, r4.. etc. I ask this because I still have my old gameboy sp that I want to add backup games into, and I don't know what to look for which, based on these names.

Yes, it's a noob question. Sorry. If there's a link here, please point the dumbo to the nearest stall.
