I used 3x 59 cards, and a full 251 card.
I recently transferred ALL of it to a single 1019, which isn't even half full.
only annoyance is that I can't transfer my damn F-Zero GX file >_>
Yeah, i have to admit that I do feel slightly ripped off, but thats quickly replaced by the fact that I'm *hoping* that the revolution uses the exact same memory card, so that when that system comes out, there will be no issues with mem card space, ever.
