Well there's alot of things to consider... You might want to make an interface for a class, or just inject a DLL, or just have a detour manager for functions.
Pointer tracing is actually really easy.. There's alot about it on the net, and I mean... you wont have any problems understand it, and its needs.
But for right now my tool only tries to evaluate which types of data that are read, i mean a DWORD could be Float, Int, unsigned int, etc. you know, so once it computes the data perfectly I might make it store it in a "wiki" format so that a human could edit etc..
