I've got 3 European Layton saves with all puzzles downloaded but in various stages of completion:
Curious Village - http://filetrip.net/dl?Lat8c7YqO4
Pandora's Box - http://filetrip.net/dl?617kSIAEvI
Spectre's Call - http://filetrip.net/dl?fOBUoslrnP
I'm still waiting for Lost Future to arrive so until it arrives I can't offer you anything more.
EDIT: In case anyone wants to know, I'm using an NDS Adapter Plus by EMS, a dedicated save dumper and reloader for DS and most 3DS games. Relatively expensive compared to DS Backup Gold but I have no experience using that product.
