So, the new Atelier Rorona Plus recognizes saves from the previous installments, Escha&Logy/Meruru/Totori (maybe Ayesha and the original Rorona? I'm not sure.) But it doesn't read from the save data that is available everywhere, it reads from the system data saves that nobody posts (since its useless for trophy saves and gamefaqs saves.)
If anyone has them, please upload them! They unlock costumes with each data that it finds on your PS3.
