I was wondering if anyone out there has/has developed/knows where to find a save file editor for the PS3 download of FFVII
You have mad skill if you can figure out how a 40 byte long checksum works without reverse engineering.i would love to add that feature to Black chocobo, but sadly i don't own a ps3 , if anyone wants to donate one to me. ill be happy to hack that checksum and add the ability to my save editor![]()
Yeah, the PSX save file can be extracted without any problem and can be used on original PSX and emulators.is it possible to make a file converter that can convert from the PSV file to a game file like .ff7 so i can use another editor? or is that checksum thing getting in the way of all that?
p.s. if you want a game file to mess around with to try to get it to work with your Black Chocobo, i can send you one
i have never seen on of the files. but as i said i would be happy to do so.You have mad skill if you can figure out how a 40 byte long checksum works without reverse engineering.i would love to add that feature to Black chocobo, but sadly i don't own a ps3 , if anyone wants to donate one to me. ill be happy to hack that checksum and add the ability to my save editor![]()

so in otherwards you basicly have to hack the DRM of the ps3 to edit the save file , yea i would for sure need at least one ps3 to even make an attempt at this.The 40-bit checksum is not a checksum. It's an digital signature created by the PS3 hardware. You can't alter it unless you have the master key which is owned by Sony.
I'll test it tomorrow. If it works, then it should be fairly simple to compare an unsigned file with a signed file, that are otherwise identical. On the other hand, I suspect that the solution on that link is referring to saves that are already signed, as it looks like this is merely a tutorial on how to copy it back to the PS3.so in otherwards you basicly have to hack the DRM of the ps3 to edit the save file , yea i would for sure need at least one ps3 to even make an attempt at this.The 40-bit checksum is not a checksum.

update: does this work ?

One thing that could be tried is writing a PSX save file to a PSX memory card, and then using the PS3 memory card adapter to copy it to the PS3. I can't think of ANY reason why this wouldn't work, but it needs extra hardware. At the very least, one needs a PSX memory card and the PS3 memory card adapter (I've got these), but unless someone can find or make drivers to connect that to the PC with write capabilities, it would ALSO require separate hardware just to get the save onto the card in the first place. I know such a thing used to be made, but I don't know how difficult it is to find today. This might be a decent starting point, but I haven't checked it out thoroughly yet.
if you get rid of the header and make it able to be read with black chocobo, will it then be able to be read by the ps3 still? would it still recognize it as a valid file?Covarr, thanks for that info
there are a few ways i know of to make a psx mem card work w/ a pc, there are adaptors (like dexdrives). also i remember a hack from a while ago that i used to read data off my psx memcard via my DB25(printer) port. if i can get the ps3 , i will go buy one of those things and test that.
looking at the hex of the psv file mav60 sent me i can just chop off the new header and then black chocobo will read it as if it were a raw psx save, so that might be the way to get that working.
NO the ps3 will not like it cause i m guessing it needs the header data there. im going to get my cuz's ps3 today, and hopefully i can find a memory card adaptor while im out. but if you edit the file as a psx save, then put it back on your memcard you shoud be able to copy it back to the ps3. this is basicly what i will be working on today. you might even be able to do this w/ a usb stick . but again let me get the ps3 and i will let you know.if you get rid of the header and make it able to be read with black chocobo, will it then be able to be read by the ps3 still? would it still recognize it as a valid file?Covarr, thanks for that info

that would be nice, but i don't have a psp/can't aford to get one on the off chance it would work with a save game editor, but thank youwhy don't you try if it works on the psp version of final fantasy VII? if it works you can pass it to your ps3, thats what i do. ps3 also converts the saves to usie in psp when you transfer them.
