Kingdom Hearts Birth by Sleep Final Mix

[Lollolo]

Hi there!!
I finally decided to try PPSSPP, since i've been playing on JPCSP so far, but when it comes to transfering save data i've some issues.
I tried to move my save data of BBSFM (patched in italian, to be precise) from JPCSP's saves folder to memstick>PSP>SAVEDATA in PPSSPP folder, but when I try to load them the game says that they're corrupted... I've finished the game (even last episode and secret episode) but I wanted to reach 100% using PPSSPP because the graphics are awesome (HD, texture resize etc.) and I think it runs faster.
Is there any way to fix this problem??

Thank you very much!!!

This is my system (if useful): Win7-64, Intel core i7-2630QM, Nvidia GeForce 540M 1gb VRam, 8GB DDR3 Ram

p.s. CryptoEngine has always been enabled on JPCSP
