The biggest blocker here is that I don't have the PS4 version of the game (yet).

There are references to FFX-2 in code, from places where I discovered something meaningful. But I have not attempted a full implementation.

It should, in theory, be possible to upgrade PS2 saves to the newer consoles that support the HD variant.

(Maybe it can also go in reverse, but I'm less concerned with that.)

I found some manual steps to attempt this, but the file appears to need a lot more massaging to correct the checksum. But it's supposedly feasible.

I've manually verified saves coming from the PS3, by hand. But I want to run some through the tool to confirm it's bug-free.

I also never tried taking a save TO the PS3. In theory it should work the same, but I want to verify this.

I couldn't find much on this online, but with any luck it isn't too different from the Steam save format.

I need to get my hands on a copy of the game to play around with some saves.

In theory I think this should work, but I don't have a good way to test it.

Going down to the International Edition should certainly work. But, in theory, it may also work going down to the US edition. (The only concern would be if the characters knew skills or completed content that was not available in the US.)

I need to break out my Vita and play with some saves. With CFW, the saves are decrypted when backed up using the various tools. So it should be pretty straightforward.

After mutating any save files, the script should also confirm/update the checksum to a valid CRC16 value.

I have done this manually before, but I need to do this using the toolchains to ensure that saves to/from the switch are indeed working.

I don't own this game yet on steam, but the file format appears to be the same as playstation.

It will be nice to verify that going to/from Steam saves does, indeed, work.

It's much more manageable to break the documentation from the main README.md into separate articles on the Wiki. The README can just link out to the Wiki.

The check is hacky, and reports false positives all the time.

Until I find a more accurate solution, let's only apply it to known encrypted data.

I recently added support for this. It seems to work, but needs tested for all permutations.
