The IMG folder that you are speaking of (1 directory up) is different. It does not have the images that are called on by the pages within those folders. If you go into help from a CDRom version, you'll see what I mean.
It's not a big deal since it's just a few help pages that are in Japanese, but I'd like to have "ALL" the files anyway... that's just me.
I'm going to re-rip it when I get time and see if I can use something else to extract the files.
