Heh I got R4 and got my girlfriend NCard, the problem is whenever she picks a wrong save type, save will evaporate. She just lost her Ouendan 2 save with Cheergirls hidden perfect S on half dozen songs
Whenever new games come out I can just grab it and stick it in my TF and it'll work. For her she has to figure out what the save type is. Maybe I should have switched hers and mine, but NCard sure freezes less.
Unless your girlfriend is as knowledgable in doctors, you'll have to maintain -firmware and savetype list- her NCard as well.
