I already had the CG unlocked though (you unlock it automatically on the end of your playthrough). Sorry to have made you all that, I think I'll just finish the game on NG+ if that's what's required to unlock that ending.
Thank you.
EDIT :
I think I'll share my save file once Im done, since there are no real "full save" around.
No, that's what I meant, it -is- a full save. That ending, scene 17, is unlocked. It's on NG+ about 1/4 through the game, I just cheated in the 17th scene since that's all that was not unlocked.
