Requesting savegame conversion...(jpcsp to psp) - jeremymd - 09-28-2012
If anyone can help me out, that would be awesome.
I tested savegame deemer with jpcsp to try to export jpcsp saves to psp. Sadly it didn't work. And even worse, I screwed up and backed up the wrong save file. Now my game is stuck in jpcsp.
Can anybody help in reencrypting it or maybe someone can point me in the right direction so I can figure it out myself(if it's even remotely possible)?
RE: Requesting savegame conversion...(jpcsp to psp) - jeremymd - 09-29-2012
I've tried several ways.
1. Savegame deemer - verified that their unencrypted format(after decryption) is different from jpcsp no crypto method. just for the heck of it, also tried it with crypto mode turned on. as expected, dead end. Not sure how serio did it once, according to his post. It could possibly be game dependent, I guess.
2. SED/Freecheat PSP - with freecheat, i'm assuming the keyfile it generates when dumping while saving is a sort of encryption key it detects while watching the save. because the keyfile i got from that wasn't able to decrypt my PSP savegame successfully(using SED english). now if my initial assumption is right, what if i can run a plugin like freecheat in jpcsp and then play a game? that way it can properly interpret jpcsp en/decryption into something SED can understand. i don't think jpcsp supports plugins yet, though. and i know i could be way way off on my assumption.
3. SED PC version - doesn't even run for me. just says kirk has stopped working...
In the many trial-and-error runs I did, I discovered that SWITCHING JPCSP CRYPTO WHILE IN GAME SEEMS TO CONFUSE JPCSP. On my test, when I do this, game freezes while loading save, sometimes just checking memory card freezes, and then sometimes it will just say data is corrupt when trying to load the savegame. so people who want to fiddle with your jpcsp saves this way, beware. back it up. don't be an idiot like me.

For now there is not much you can do,you'll have to wait for Hykem to return

holy crap!!!!!
Magicsave is the key!!!!!
SUCCESSS!!!!!!
TIP: Use SFO type 2 and the data you upload to your PSP has to be in jpcsp crypto mode. Hurrah!

it doesn't work on all games though. i tried to port a save for fate/extra, but it's still seen as corrupted.
maybe the game's save format is more sensitive than others, i dunno. it rejected both raw and crypto mode saves as invalid, and didn't even show the image like it does in those screenshots.
RE: Requesting savegame conversion...(jpcsp to psp) - jeremymd - 09-30-2012
1. does the magicsave menu even pull up?
2. were you able to enable read invalid data?
3. after enabling that, did you try mixing up the SFO file and decrypt types? I imagine the necessary combination would be game-dependent so play around with those.
and remember that you should not be in the load game screen while changing these settings. preferably you should be at the title screen.

1. yep, menu pops up.
2. i can turn everything on and off at will, yeah.
3. sfo juggling doesn't change anything.
did the settings on title screen, yeah.
the savefiles are still shown as corrupted data. i'm guessing either this game's really picky about the encryption, or the plugin simply doesn't fully work with my psp model/cfw version.
RE: Requesting savegame conversion...(jpcsp to psp) - jeremymd - 09-30-2012
oh yeah maybe that. i'm using procfw 6.60..
RE: Requesting savegame conversion...(jpcsp to psp) - serio - 09-30-2012
