Hacking problems with nintendogs save.

[fugazi]

I have a new ez4lite micro, i have passed all my saves of my old supercard to my new ez4lite, all works ok (animal crossing, mariokart ... ) ,
but the nintendogs save dont works, appears the door to knock and my dogs are disappear.

another rare thing is that, if i copy the nintendogs.nds.dsq and nintendogs.nds.sav in my girlfriend supercard , it dont works , only one dog is visible , called perro. ????

someoneone knows something about nintendogs saves.

thanks and sorry for my english.
