Yep there is a way, as long as you're on CFW (any CFW) assuming you have Mlutiman,plus your savegames on usb
1- Enter multiman & go to MMOS (file manager)
2- go to dev_HDD0/home/0000000x(your user profile)/savedata
3- look for your RE 5-6 IDs(if you don't have them create new savedata for both of them)
4- now when you enter the game id folder you'll find a bunch of files over there. copy your old files to this folder except PARAM.SFO,remember everything except PARAM.SFO alright. now when play the game you'll find your old save game,remember don't copy PARAM.SFO
tested & guaranteed 100%. i hope this helps.
