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 The AV diagnostics will indicate if the other ROMs are bad or out of date by 'bonging' at power-up.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.)
