Resources and packers
 

hi,

this is a silly question, and i know i should already know that...

when coding a pe packer, what i should preserve from resource section to gui appz continue working? just the top-level directory entries, or also the directory pointed by these? (i know i must also preserve the icon)

so far, all my pe packers work well for console appz, but fail miserably with programs that dare to use resources

thanks in advance,
ancev
