Is there a certain file on bd+ discs that contains the bd+ code? How does the vm in hw/sw player extract the information that the disc requires to play?
Edit:
found better explanations for the vm:

That last one is a gold mine of information about the vm instructions used. Wish I had a bd+ disc to test with.
