Good luck for your request, i try to find a save too for a long time...
I ve send 3 times my saves to savewizard but they never add cheats for this game....
Wich trophy do you need ?
Share your save and maybe i could help you.
Can you please share your save to see if you re more advanced than me ? I need this trophy too, it's not hard just grind...
And try to send your save to savewizard.
