Hacker Motoharu has released version 2 of psvpfstools. The toolkit now has full PFS support. The release contains binaries for Windows and Ubuntu.

What is psvpfstools?

Decrypting the PFS Filesystem can be done on a hacked PS Vita, but the benefits of psvpfstools is that it runs standalone on a PC, and understands the full layer. As such, it is compatible with 3.61+ games as well. Psvpfstools 2.0 can decrypt in particular: gamedata, addcont, savedata, trophies, appmeta, addcont root.

Full changelog, from the source:

Support of icv.db format (savedata, trophies etc)

Keystone and Sealedkey parsing and Keystone sanity check

Complete rewrite of unicv.db parser (to accomodate icv.db)

Support of Merkle trees (related to icv.db)

Bug fixes that were in previous versions
