Hacking Is there a way to backup Heavy Rain without losing my save?

[Sportsmaniac1322]

I asked this on Ask GBAtemp, but I didn't get a definitive answer so I'll just ask here. I have my whole library backed up except Heavy Rain because of all the problems I've heard about it. I've read in many places that I have to "delete all pre-jailbreak data" from Heavy Rain before I back it up. Does this include the save? And if it does, is there I way I can restore it once I have the game backed up?
