Hacking Weird Sky3DS thing

[RoDryBones]

I was playing One Piece Unlimited Red World and everything was perfect (Played about 12 hours) but when I turned on the 3DS normally and launched the game, after the main menu it just shows blackscreen. The save data is not even corrupted because I can choose my file.

EDIT: Nevermind, I fixed it downloading the same rom again and restoring the save.
