the only villain on staff
Kingdom Hearts -HD 2.5 ReMIX- was released in Japan a few days ago and already it has been discovered that both Kingdom Hearts II Final Mix & Kingdom Hearts Birth By Sleep Final Mix retained their respective dual audio Theater Mode from their original PS2 & PSP releases. While looking through the data from Kingdom Hearts -HD 2.5 ReMIX-'s disk, YouTube user crazycatz00 has also discovered that most of the English data for Kingdom Hearts II Final Mix is also on the disk.
The English data from the disk cannot be accessed normally, but by using a hack to trick the game to believe it is running in English, it will load the English data for Kingdom Hearts II Final Mix including English dubbed cutscenes & text files and also invert the controls to the NA/EU/PAL standard. He has also found Spanish & French language data for certain menus and textures on the disk. You can see crazycatz00's video of Kingdom Hearts -HD 2.5 ReMIX- running in English below:
