Decrypting SaveData error: "Unexpected file type"

[jpenalbae]

I'm trying to decrypt persona 4 golden save file. Copied the save to my computer using qcma, extracted the savedata.psvimg file using psvimgtools-0.1-linux64, and then tried to decrypt using psvpfstools but I'm getting an "Unexpected file type" error.

$ ./psvpfsparser -i ux0_temp_game_PCSE00120_savedata_PCSE00120/ -o save_dec/ -f http://cma.henkaku.xyz

I fixed the problems with decrypting savegames in my fork here https://github.com/cuevavirus/psvpfstools

I'm getting the same error message when using master branch from your fork @cuevavirus

I can take a look if you don't mind uploading your save file

You can find the save here:

The error is due to this check failing.

This save data contains many files of type 0x0004 which is not described here.

Decrypted save data is attached.

@cuevavirus Do you have a plan for a generic fix?

I have 91 saves and of those only 28 did not have this error so it seems to be a common problem*. I can send you a zip of the saves if that would be helpful.

Even for the successful one many had warnings like this: [WARNING] Directory SCE_SYS size is invalid Building file matrix... [WARNING] Invalid file type for file SDSLOT.DAT. assuming file is encrypted

(These are all files that have been backed up to PSN and then redownloaded which I suspect accounts for the SCE_SYS size being invalid, I've noticed the PSN size and the Vita size clash frequently)

*I suspect it's slightly more common than that number would indicated because some of the successful ones are ones where save data has been generated from starting a game but I haven't actually made a save that contains anything so they only contain the sce_sys files.

If you could upload the saves that'd be great, so that I can see what other file types there are. The warnings are always there when decrypting savegames, so I will probably remove them.

I've uploaded the files to a dropbox, and am happy to send you a link if you could drop an email address or some other contact method (the files are associated with an account I still use and some are for online games so I'd prefer not to risk dumping them all publicly)

(I can be reached at mygithubusername AT gmail.com if you prefer that)
