Cheat Engine

[Rebelicious]

I am not sure if Cheat Engine can do this, but I think this'd be the place to ask.

Let's say that, instead of tracking down a number or an address which I already know, I'd like to track down a value of a variable that is unknown.

For example, I want to much about with items in a game, in this case Elven Legacy, which have no obvious in-game variables that I can search for in a binary, numerical or hex-based environment.

My idea is here to simply scan all addresses in the game. Then move something in the game (i.e. equip an item, for example) and then discard all addresses that have not changed.

Eventually, I should be able to narrow it all down to finding an address that does not change continuously, but changes every time I add/remove said item in said slot.

Can this be done in CheatEngine? And if not CheatEngine, is there some other (preferably free, Windows-based) program in which it can be done?

Use search for unknown initial value and after that use increased/decreased value or simply changed value. To make things a bit easier along the way I would recommend while your looking for your value, after a few searches to go back to game and simply run around open close menus and the like anything that wont change the value of address you are searching for and then search for unchanged value. That usually gets rid of massive amount of values that you do not need. At least when you are looking for unknown values.
Items will be more difficult they tend to be simply arrays of bytes something like for example A5 C2 XX XX XX 22 XX XX XX 01 XX XX just an example of course could be completely different way of storing item information but it tends to be id of item and in array it will specify all junk related to item. including how its placed in inventory quantity attributes of it. simply put its more complicated then simple value searches.
oh yeah if its rpg and it doesn't give you numbers for hp/mana and the like look for items that increase what you are looking for. then search for unknown value put on item that increases...lets say hp by 50... in next search specify increased by 50. take off item search for decreased by 50.
of course the way game stores specific value is up for debate. hp tends to be stored as float. could be something like visual valuex10 or some such method
edit:
heres a link for a pretty good tutorial on how to look for items. its not for this game but its worded very nicely and should give you a general idea on how to look for item
