Description
You once used the Full Cheat Code to unlock everything in the game (which prevents you from unlocking Achievements / Trophies), but now you want to get all of the Achievements / Trophies!
Solution
If you've previously used the Full Cheat Code, you can start unlocking Achievements/ Trophies by erasing your game's save data and starting fresh.
Be aware that this will also reset all of your Stats to zero, so you might lose progress on other Achievements / Trophies.
Go to the Menu --> Stats, and press the big red button at the bottom. This will erase your save file.
You can now unlock everything the normal way, and you will be able to get the associated Achievements / Trophies.
