This new option doesn't work for system data right? When I load the 3rd Birthday's system data I get this 0x80110306 error. I'm also getting the same error above when I try to load the game.

It's probably because of the SAVEDATA mode the game is using. Anyway, I have some of the games andutrache listed, so I'll run a few tests to see where the issue is coming from.

Well I've tested the savedata for kingdom hearts birth by sleep,the only thing that i don't like is that when you pass the 1rst message sometimes the emulator will pause the game,and you have to keep pressing run to play,after you can control the character there is no problem and the savedata works fine.I guess the game pauses because is reading the encrypted savedata,I have tested this on both 1993 and 1994.Thats not a major problem, i mean if the game still works you can just play at level 99.

Isn't it just enable the Handle Save Data in Crypto mode option, save in game, and then move that save to your psp?

if i do that the emulator won't accept my plain saves

[andutrache]

use snapshots. also some games can't be saved.

Is there a way to input an encrypted save and output a decrypted save?

enable handle savedata in crypto mode for encrypted savedata, turn it off for decrypted savedata.
