There is a way to copy savegames,and i'll show you:
1. Download the save game you want,which is 100% completed.
2. Copy it via Multiman and overwrite every thing except the PARAM.SFO (to go to you save game go to Dev HDD00/home/000000001/savedata/BLUS or BLES what ever (& remember copy the internet savegame to your savegame but don't copy the param.sfo of the other savegame)it works in almost all games Skyrim,Arkham City & Asylum with no need for Param.sfo editor.
