S2 Version 1.1
       Date: October 9, 1996
S2:    Checksum: 1300

       Changes from revision 1.0:

       This revision eliminates a 'buzzing' sound that is occasionally
       emitted from some games.  If you experience this problem, use
       this version to replace the S2 in your game.

       This version of S2 requires that the other sound ROMs be at least
       Version 1.0.  The AV board diagnostics will indicate a bad S3, S4 or S5
       by bonging more than once at powerup.

       (3 bongs = bad S3, 4 bongs= bad S4, 5 bongs = bad S5)
