I can make a US NTSC Version for kingdom hearts although i need the information of the disc. (Disc size in bytes, the beginning and ending offsets for the intro, ending, secret ending and the pre-intro.)
For people with the PAL Version of Kingdom Hearts, it may take a while for me to make an extractor. Due to decoder decoding it to 29.97 not 25fps. It was easy to change the framerate of the extractor for FFXII due to it having no compression format (except for the ATRAC3 format

Heres the link to extract the Pre-intro from Kingdom Hearts Final Mix.
