Guys, I have a dilemma. Last month my bro was the one that first played my Muramasa Rebirth retail copy. Needless to say the save files went on the game card. Now he has finished the game and got all endings but here's the catch. I cannot get any trophies with his save files on the game card.
Should I delete them and forget all the hard work my brother put in the game. So I can get my trophies or should I use his game files to get easy access to the endings without the need to grind?
What would you guys do?
