Called once a complete SNES screen has been rendered into the <code>GFX.Screen</code> memory buffer, now is your chance to copy the SNES rendered screen to the host computer's screen memory. 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.
