*Say YES to overwrite the existing folder notice.
4. Copy the exdata folder to: /dev_hdd0/home/0000000X/
3. Play the game.
Where 0000000X is the number for your profile (mine was 00000002).
Uploaders Note: It will say (Trial) in XMB but its the full game. Since it offers to save and there is no Purchase Full Game in main menu...
Edited and tested myself.
Creds to EXEtrimall and Juan Nadie for the algo stuff.
