Well then, you decide :P
Thanks for your replies.

I still think it's needed in some cases though. And it wouldn't waste time if the scan is only performed for roms missing from the specific set zipfile, not all missing roms from all sets.

P.S. isn't it the same for sets with CHD files ? The roms are in a zipfile, and the CHD itself is in a subfolder.
Besides, what happens if you have zipped sets, but rebuild the missing roms with "compress files" disabled? Doesn't this produce the same thing (i haven't tried yet)?
