Question for Charlie - about Action Replay.

[GunBlade]

Well, I found the Gameshark image to download in a different site with another file seperated from the image with an .sfv extension.
Does this mean anything to you?
My guess is this is a file that you can somehow place on a memory card to make it "act" like a gameshark key.
The question is: if this is actually the case, how can you transfer a PC file to a mem card?
