help me find a way to make a full copy form one VMU to other VMU

(including VMU games, uncopyable saves and image icons for the lcd display).
I Know i can do this with the Ems "DC Double Power". but is there any other way.
Using a Nexus 4m memory card with PC Connection, that I have.
But I'm specially interested in a special Dreamcast Utility Software that is able
to manage, Memory cards for DC, This must be possible because the Web Browser form
Planet Web Software allows us to send and receive (by e-mail) any file on the VMU
including VMU games and uncopyable saves (but you need to be on-line to do this).
There are now available so many utilities for dreamcast, like VCD viewer ,
GB emulator , MP3players , Way isn't there any VMU copy program (knowing that
the one that dreamcast provides is no good).

If you think you can help me Please send me a e-mail to: goose_xox**********com

Thank you. GooSe XoX
