I stumbled into a little problem when I scanned the Passigar SCI/AGI DATs.
Well... I have a lot of the files included in the DAT's, but far from all, so I was making a Fix-DAT to send to a friend who could put the remaining files on his FTP. When I browsed through the Fix-DAT to control it I found out there's MANY crc32's that are the same, of course this is because the files itself is the same, but I don't need more than one copies of each file, especially not since my friends FTP is somewhat slow...
How can I tell ClrMame to only include the files once in the Fix-DAT?
and if this isn't implemented, could you please implement it? :)

Thanks!
