I remember a program "ArtMoney" or some such from my early childhood. It would take snapshots of memory for a particular process, and allow you to search for a particular value. It supported a differential analyisis, such that you could enter the value of an easily controled variable (say HP), and then search for it, change the game state, search again, and narrow down the range of possible memory addresses.
