Kingdom Hearts 1.5 HD Remix [BLUS31212]

Hi. I've put the same post in "support" but anyway.

I've played RE:Chain of memories almost complete with some problems but i've could fixed them; but now i have this problem:

When i go past the final boss and the ending, the screen freezes in a point. I've tried with OpenGL and Vulkan but still can't.
Any helps??
It would be enough with a savegame with reverse birth mode unlocked too. In the end, i just want to play with riku.

Thanks in advance.
