Use Xplorer360 beta 6 instead of Action Replay. It definitely works under Windows 7 64bit natively, but you have to grab msvcr71.dll to make it work.
I'm having the same problem. I got that DLL file and I can't put anything in xplorer360. Its not working at all. I know my card and my card reader isn't damaged becuase I can at least use the gameshark program on it from a windows xp computer. Thereh as to be a way to do it!
