Item description:

I put together most of the saves that are wanted for this game in one thread. After testing all these saves, I have found some other methods to get certain trophies, which seems to be easier than what was stated in those threads.

These saves are for US Region (CUSA5933) and EU Region (CUSA5786).

* Resign the CUSA file within the downloaded zip file and not the zip file named Save Pack.

I re-regioned this save from ady's Thread. Credits to them for sharing this save.
