In the final boss cutscene, when King transforms into the evil one the game crashes right after his transformation (Before Raio says "King! What happened to you?!")
but only if you replay it from the G-center after beating the game.
I believe there is a slight difference in dialogue when you beat it for the second time because the crash does not occur during the story.
It specifically crash when the flag for the "Matter Invert" quest has been completed.
Skipping the cutscene by pressing start allows to play the quest without crash, fortunately
