Good interview, and good answers
The included hex editor i must admit is good, VERY limited but it makes the basic tasks that people wants (find and replace)

That’s because those save files are protected by “encryption, compression, checksums, second level encryption, and so on,”...
So we basically make all of that invisible to the user.
This way to explain it is funny, with the security of PARAM.PFD "cracked" anyone can do the same with a standard (and more powerful) hexeditor

The important stuff is the decryption of the save files itself... but if the list of "known decryption method" files is only 70 games (and maybe some of this 70 decryption methods are public)...

Are only 70 games because is true what he said about is a long work to understant how the decryption of 1 game save works (are files generated by the game, so developers of the game can use whatever method they want, is different for each game company, and can be different for every game)

This is the hard work, when the file is decripted is "only" a question of "find and replace"
This is also the reason why this companies always acusses themselfs to "steal" codes from others... is very easy to copy the code after somebody imagines the positions and the values to "find and replace"

---------------------------
The other protection is in the PARAM.PFD files
Both are "invisibles to the user" (like he said, heheheh)... to protect themselfs obviously

why don't they bypass the saves completely and just hack the memory? after all that is how cheat codes used to be like back in the old days, it's quite laughable that people are comparing it to cheat devices back in the day.

also these guys are so concerned about the trophies, so what? they don't do anything apart from give you a big ego and that's it, who cares? i don't even care about online anyway.

Some people buy the product. It's their choice to feel like GOD in a game.

Nice read, I wonder why this is only for the PS3? I would think the xbox 360 saves would be much easier to edit and it's easy to use anybodies saves.

@MajorDisaster i think that's why because it's a lot easier to modify a save game of xbox 360 than a PS3 one. Nice marketing move.

Can we now make savegame exploits?

Although with E3 apparently "releasing" the ps3 keys this point maybe mute, but ...

Since it's now possible to decrypt, modify, and then recrypt savegames - would it make any sense to investigate using this to create a custom savegame which would exploit a game and possible allow ppl to run unsigned code from within GameOS? Similar to the original exploit with Vita. I'm certain this would be a lot of work, but the honest question is what would we gain from such an exploit?

I'm guessing *if* this were possible, all we'd gain is a way to run arbitrary code from GameOS regardless of what OFW sony cooks up (as we are only exploiting a game and not the OS). It still means that a significant amount of time would need to be invested in trying to exploit GameOS and trying to gain access to LV1. Or am I just spouting nonsense?

Regards,
AI
