Cheat Engine

Could you use Cheat Engine's capabilities to find changing values in files, such as DLLs, in real time, ie while a game is accessing them?

And also, do you any idea where to find a program that reads DLLs for you, all 3 types?

When a game uses a DLL it loads it into it's memory.(normaly in it's prefered location, but else it's closest free spot) That memory is also scannable with cheat engine.

But if you're talking about a normal file not right now. I could of course hook all file reading/writing api calls. (But there are a lot of them)

All I need to know is do you actually read DLLs when you look at the memory in Cheat Engine as opposed to looking at it with wordpad or something?
Does Cheat Engine "translate" this for you.

What you see when reading the memory with Cheat Engine is a bit different that what you see when you open a dll with a filereader.

When windows opens a executable file (DLL is a executable) it looks at the header section to see where to copy parts of the file too.
e.g. : Bytes $1000-$90000 to address $00400000 , bytes $90001-a0001 to $00500000, etc...

And it'll fill the import table and initialize several other sections too.

Also, if the file is compressed with a exe compressor like upx then what you'll see in memory will be the uncompressed version of the dll, while with a textviewer you'd see the compressed version.
