The problem is that you have to cope with different sized SNES rendered screens: 256*224, 256*239, 512*224, 512*239, 512*448 and 512*478.

 			The sound generation rate on a SNES is directly proportional to the video output rate. Displays that synchronize with the vertical refresh but have a slightly lower refresh-rate than the emulated system can experience sound drop-outs. It may be beneficial to provide an option for users to configure <code>Settings.SoundInputRate</code> to suit their own systems. Setting <code>Settings.SoundInputRate</code> to a value that matches the actual output rate (i.e. 31977hz for 59.96hz) or lower will allow the users to eliminate crackling. A range of 31000hz to 33000hz should be inclusive enough for all displays. Use of this setting paired with the <code>S9xSyncSound</code> function can eliminate sound discontinuity.
