There should be a way to extract the audio and reference it back to the video stream to play the audio. I just can't figure it out myself. Hopefully someone who's more familiar with this issue can step in and help.
I've implemented a method in r3534 to decrypt the files from this game using the simple XOR 0x7B method. This is still a work in progress
Does it help to play the music?
Think you
the music can play now.
There are 21 bin files in USRDIR\DATA\ , but jpcsp just decrypt the first one which jpcsp found. If you want jpcsp decrypt next bin, you need restart jpcsp.
for the 21 bin files, 20 of them have 2 video streams, yet jpcsp suppose to switch between them, but not every time it work.
The last bin files, the biggest one, it just have one video stream, but it is 00:22:29, a litter long. for someone didn't want to see this video from start to end, this game deal this video as CHAPTER 1, CHAPTER 2, CHAPTER 3 and CHAPTER 4.
but if jpcsp try to play CHAPTER 2, CHAPTER 3 or CHAPTER 4, it will be blank screen
