Hacking How to backup gba saves ?

[Keylogger]

I have a 9.0 N3DS with Cakes CFW and some GBA injected VC games.
How can I backup my saves games to use them on another 3DS?

Savedatafiler doesn't seem to work

IIRC, there is no easy way yet (that is, no one created a tool for that yet, which is the reason I'm staying away from GBA VC games for now).
