what exactly does it mean to copy full contents of cd to temp dir. install game to that directory or put image file there?
well, either so told you wrong instructions, or here is the explanation that seems the most appropriate. I suppose you wish to copy a CD and apply a crack before that. Well, create a temp directory (c: emp or whatever), copy the content of the CD to it (Blindread is just great for this), extract the crack to it to replace the original file, then burn the all thing to a CD-R (Nero also works great here for a multisession).
Hope i could help u,
