When this is set to Yes, the DMA is delayed during emulation and transferred in sections instead of simply copying the entire data at once. Most games will work with it on in 1964. There are a few exceptions, such as Conker's Bad Fur Day. You may notice a little speedup with this option off. The Default is Yes for maximum compatibility. If you experience a game that has sound that has disturbing cracks and pops, it is possible that turning this option off will help. As a specific example, Carmageddon's audio will benefit from this option off.

  • Turning this off can get you some more speed. Most games will not matter with this setting, but a few require it on, while a few others need it off. Tweak away.
  • 1964 0.85 refers to DMA as "DMA_Segmentation" while 1.1 refers to it as "timing_Control".
