[I_Will_Never_Die]

I mean the registry files of a game. Like a software that can detect which new parts are added in the registry when a game is installed.

I need a software like that coz some of my games installs so damn slow and I want to backup it. What I need to do is install and wait for a long time and after the installation, I will use the .iss complier to compile it and make an installer of the installed game on my hd. Problem with thise method however is that I dont have the registry files. Plz help. The games i need to backup are Guilty Gear XX and 25 to Life.
