Save and load: BRKBK

       Name: BRKBK                                                   [Show more]
       Type: Subroutine
   Category: Save and load
    Summary: Set the standard BRKV handler for the game
    Context: See this subroutine in context in the source code
 Variations: See code variations for this subroutine in the different versions
 References: This subroutine is called as follows:
             * DEEOR calls BRKBK
             * SVE calls BRKBK


 BRKV is set to this routine by the BRKBK routine, which is called by the
 decryption routine at DEEOR just before the game is run for the first time,
 and at the end of the SVE routine after the disc access menu has been
 processed (so this resets BRKV to the standard BRKV handler for the game).
