Congratulations.

It seems when completed, this will lead to save file transfer between psn accounts. That is a feature i want from the start.

I also hope savedata files can be exploited just like PSP. Hope i will be able to run homebrew on my Vita soon.

Would I be able to load this with the retail FF X/X2 remastered version? Thank you

P.S. sorry for the newb assumptive post, I'm just trying to get my ducks in a row here. I know people like me are annoying.

amazing work mr. gas! Keep up all the good work! This has the potential for being a huge year with the Vita scene! Between this, ps1 loader and open source TNV it will be a really fun year! Almost like the good 'ol DAX days!

Awesome news, I'm surprised at how little notice this has gotten by the community!

So the next step would be reencrption and the development of some kind of debugger? I'd assume both of these will come with major complications, but all progress is progress, this is a big step, very Awesome news! :D

Just out of interest, what kind of encryption does the vita use for its saves?

Congrats, this seems to be great progress!
I personally hope this reenables cross save functionality for lower FW Vita.

Awesome work, thanks! :)

Even we can't use it for Vita Homebrew at the End, manipulating Savefiles is also a good Thing. Convert them, Cheats, Mods and who knows which Doors it opens for other Stuff when it is possible to re-encrypt them (with the Knowledge). Possible that other Stuff is in the same or a similar Way protected as Savefiles. But that are dreams of the future. ^^
