Sound ROM Revisions

Pinball Home | Tech Support | By Game | By Date | ROMs


       Version 1.1
       Date: October 9, 1996
S2:    Checksum: 9300

       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 on the Audio Visual board in your game.

       This version of S2 requires that the other sound ROMs be at Version
       1.0 or later.  The AV diagnostics will indicate if the other ROMs
       are bad or out of date by 'bonging' at power-up.

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