PS3 Save Data Utility Payload File help?

[xDreadwingx]

I'm trying to decode a PAYLOAD.file from a game save, so I can edit it, only when I open it with Hex Editor or Notepad++ it is just a bunch of random letters, symbols and numbers.

So what could I do so I can understand it.

The save is from Transformers War for Cybertron, The custom characters, I want to edit it and then put it on my PS3.

If it is of any use, I can make the PAYLOAD.file available for download.

you need Offzip & Packzip to decrypt PAYLOAD.
