I see what you mean Paul. I think you've seen how mine works
No need to be too fussy about certain files as long as it needs the original disk. What you'll find is loads of steps can be simplified by using RAM: etc etc. Can understand why you don't want to mess around finishing it though. I tend to do mine little bits at a time when I'm totally board, plus I enjoy it!
BTW, how did you get those nice formatted bullet points in your post?
