Decrypting SaveData error: "Invalid zero vector" #42

Open maledin opened 5 years ago

maledin commented 5 years ago

I'm at wits end trying to transfer/decrypt my Vita's Stardew Valley save so that I can keep playing on my PC. I'm on firmware 3.70, and from what I've gathered, there's no way to install Vitashell/other save managers on my Vita. As such, I'm stuck trying to decrypt the save file on my PC, following this process.

Anyways, I was able to transfer my save file to my PC using QCMA, successfully used psvimgtools to decompress (?) the file, and finally attempted to use psvpfstools within Windows Command Prompt to decrypt the data. Suffice it to say, I have not been successful using that utility, encountering an "invalid zero integer" error that stops all my progress. I have no idea what this error message means, nor have I been able to find any information about it online.

I'm certain that I have the syntax of the "psvpfstools(.exe) -i (original file) -o (decrypted file) -f cma.henkaku.xyz/" statement correct, yet I've never been able to complete the process.

psvpfsparser-error

Is this a known bug, or did I make an error during the process? How do I proceed?

Thanks!

@maledin It seems that this is the case of some unexpected data that I was not able to encounter before. This is a new bug.
