I'm afraid that, to do that, someone would have to reverse-engineer one or more of the game's executable files. Unfortunately, doing this is a FEDERAL CRIME! One reason reverse-engineering the executable files of commercial software is a federal crime is that it is one of the steps toward DRM circumvention. For instance: what do you think a "no-CD crack" is? That's right: it's an .EXE file that's been cracked to disable a game's CD-based DRM (such as SecuROM or SafeDisc)! In order to crack said file, someone had to reverse-engineer it first. This is a BIG reason why the U.S. federal government considers reverse-engineering of .EXE files to be a HUGE no-no!
