FF7 Tools / Re: [RELEASE v1.9.82]: Black Chocobo - FF7 Save Game Editor

I know it's been a long long absence But in a sense I'm back. still tinkering with the ps3 side of things.
Months back I got one save to load on the ps3 port of FF7, then tried the same file onto a friends console with no luck.
Compared a few hundred identical saves exported over and over.
Couldn't find any rhyme or reason to the checksum created on export.
Got access to a jailbroken ps3, and the saves load normally there.
Just recently got back to coding and such and figured I would jump back into this if no one has accomplished the PS3 port yet.

Well after a long absense myself, between holidays and such I am back.

Bad news is still no breakthrough on the ps3 coding. I have messed with other games and some don't even add a checksum when exported.
Why on earth protect a game that's this old?
Also followed several dead leads on the "phrase" the ps3 uses to code these exports.
I was told by a few guys that each game has the checksum formula that the ps3 uses for it.
Kinda makes sense seeing as a few games don't even get a checksum.
still prying at it though guys.

Zophar out,.,.,.

The ps3 uses ecc on most of its encryptions. But there are also different keys for different objects it encrypts.
And the file itself isn't. Encrypted all that well if it is at all. Aside from the header changes there is basically no change to a standard ps1 save file.

If we could come up with the ecc key they used for this specific purpose it would be tons easierto narrow down which ecc formula they used.
But nobody is sharing the key info openly after the geohotz incident.

The algorithm is still not clear to me.. I have been looking into sha5 and several more uncommon checksum styles and can get close to the checksum in the file but not exact.
Just letting you guys know I haven't forgotten

Still sifting through the garbage so to speak.
I have run crc32, md5, and SHA1 checksum data and nothing matches what they have going in there.. Unless they took the file checksum and did an additional algorithm off of that.

Still digging, I have poked on a few shoulders in the decrypting flock to see if we can get a few of us in a colab and get this thing knocked out.

If you can enable the saving of .psv I will work on the checksum. Its been a little while since I did much dev work, but if I can figure it out I will get you the info to complete it.

Probably need to add a pop message to let everyone know its not fully functional in case they try to use it.

I would be glad to help out with the ps3 aspects though.

Whats the word on the ps3/psv save editing?
I stand by ready to donate when its working. I dont have all the equipment to do the save the long way.

I have played this game since the days of the old psx and got it downloaded on my ps3, already into disc 3, but I would like to be able to mess around with it like the old days and be level 60 before leaving midgar.
