How to create an GFWL working offline profile to use old save game?
 

I have Resident Evil 5 and Batman Arkham Asylum save game (For now on SG) data under My Documents folders. I didn't know about the existence of XLive folder (For now on XLF on:
So, i format the entire HDD making a new installation of the OS restoring My Documents folder; until this point everybody knows what is my problem and is the corrupted save game cause the XLive profile is linked to the main Save that was erased on the formatting process.

Searching on Google it seems everybody forgot this issue and start the game over. However, i know there will be a solution but i need help to found it.

I start whit RE5 making an Hex Compare between a New Game and my old SG and found that the starting HEX Values are different on every New Game! The rest change making progress on the game. For that, i tried to put the New Game starting Hex Values on the begging of the Old SG thinking that this must have some key linked to the GFWL profile; but doesn't, game still saying "Save Game data is damaged".

As far i can see, the values that i have to modified are contained on thhe main files of XLF; but how should i modified XLF to make it work whit the old save game?

NOTE: Since i format the HDD and this issue has pass almost 6 moths; try to restore delete files won't work.
