Akham City save problem

[inserttwo]

So, I was using the True Blue a few weeks ago. But, then I read about the all DLC fix patch released. And them I did everything to try it out. Changed the fix from the True Blue one to the CFW 3.55 one. Updated the game and all.
Well... the game works all right now. The DLCs are avaliable and working (already played them all). But, my save files is missing. I don't know what happened. But, I imagine that the new game is not the same of the previous. So the save is not being reconize. So I'm thinking about poaking around the Internal HD looking for the save and try to put it in the "right spot". Anyone knows where the saves are put?

And although I really liked the game, I am not eager to doing everything again (Missions, Side Missions, Collection everything). Anyone had the same problem? Was able to fix it?
My Arkham City version is the BLES one.

Well that's your problem. The TB patch was for the BLUS version and if you've done a new patch for the BLES version it changes your save ID. look in dev_hdd0/home under your user account folder in the save data folder. find the game ID for the BLUS version and the BLES version. Look in the BLUS version folder and copy everything except the PARAM.SFO to the BLES folder

Make a backup first!!!!

Well... I did what you suggested. And in multiple tries (Deleting the BLES save, putting the PARAM from the BLUS version, and all possible ideas I could have). In all of them the system actually reconize the progress I've made. But, when I try to continue the game (enter the open world), the system's stays loading forever. When I try to get out of the game, the system restarts. So, aparently, the only possible solution now is to change my BLES version and get a BLUS version.
