Something that can search and replace a hex string but for multiple files?

Question

Hi I'm looking for a hex editor kind of thing but for multiple files? Can Windows Grep do this or does it only handle text strings?

But Perl by itself can do this sort of thing

perl -i.bak -pe 's/\xD5\x37/12/g' *.dat subfolder\*.* otherfolder\foo*
