Hey all. Created an account just to post this.
Hopecord's saves DO work, but you have to use a Ps3 save resigner for them to be recognised on the system. I personally used Bruteforce v3.8.15 as the latest version was not working for me.
The only problem was that I don't have the same DLC that Hopecord did on his account, so for the saves to work correctly you would need to have those DLC. From memory it was the free Cerberus one and Arrival.
If anyone wants help using the save resigner, feel free to respond here or PM me.
