Problem with VBA and NDS

[jmln1]

Maybe the title doesnt says a lot...

This is what happens:

I played all 3rd generation games in the VBA emulator, but this year I bought a DS. I tried to transfer the saves to the Slot 1 card (I have the slot 2 card too)

But, when I try to boot the Pokemon Sapphire or Ruby, the message:

"The Save File has been deleted..." is displayed.

I can open the saves with the emulator, but i couldnt find a way to do it in the DS. After investigating a lot, I saw that my saves were 64k, when it should be 128k. So, my question is, is there a way to fix this? Or there is any way to "copy" the data of the save to a healthy save, without having to start a whole new game? Thanks for the answer...
