is cross save without PSN possible?

[ErnieBall]

Like many of you, i am using my Vita on an older Firmware (3.18 in my case). The only feature i really miss is Cross Save with my PS3.
I was wondering how the process works, my guess is that the vita savegame gets converted in a "neutral format" and then is converted to a PS3 savegame and vice versa. I was thinking, if this con version is done on the device itself, there might be a way to "sniff" the converted savegame with some kind of proxy / tool and get it on the other device without the need of PSN. Kind of like how you can use PS3 Proxy Server to install a certain firmware to your vita that is actually saved on you pc instead of being downloaded from PSN.

As you might have noticed by now, i am not a developer, i don't know a lot about the concept of proxy servers and i don't know anything about how the vita handels Cross saves. I was just having this idea and i am interested what someone with better knowledge on the subject thinks. So please tell me what you think.

If you have a ps3 on cfw and are using open cma for your vita, you can use a browser to find the specific files..... It might be worth just copying them over for schlits and giglez. When I upload a cross save, I am always asked to rewrite it or not reguardless of if the game had been originally saved with that system.... I'm doubting that it would be that easy, but if you have the same psn ID (online or not) on both systems it may. Otherwise, using a hex editor to find the term ="psv" may just need to be changed.... No idea... ps3 been gone from my house for a long time. This isn't the answer your looking for, but my thoughts off the top of my head since you haven't gotten a reply yet.... maybe someone will point out how wrong I am and involuntarily help you out :->

(Alot of games are in numbers as I remember.. might have to look up the ID for your game)
