Live Memory Dump

Ive searched the forums and couldnt find the answer im looking for about dumping the memory of a game so I can hack codes. So is there anyway to dump the memory for the game I want and have it save to my HDD (not official) my memory card is way to small for this particular games data. (Socom 2) I dont have a DVD drive so I cant pop the disc into that and get the data that way although I do have an exploited PS2 if that would help in my quest. Any help will be greatly appreciated guys.
