really not in mood for searching .. but google for ''.dll editor'' or like ''.dll extractor'' ..or something like that.
one program that can open .dll files is
ResHacker
It can extract info, icons..etc from .dll files. maybe it helps..maybe not. if not, then just google .. or try to search download.com or softpedia.com
download.com and softpedia.com are only for program name usually...you cant get cracked version there so use emule or torrent sites (in emule watch what u download...theres lot of fake shit)
