Right showing HD and no dithering. ]]Dithering is a technique to increase the amount of color and shading that can be done on a system. The effect is achived by using lines or dots which are then blurred by the low quality cables (composite or RF) that the system uses. |

− | + | [[Genesis]] relies heavily on it. The waterfalls in Sonic the Hedgehog are a classic example. A few [[SNES]] games use it as well (eg. Metal Warriors). Certain PS1 games, such as Silent Hill make heavy use of dithering. In that game it is used for shading. Many other PS1 games have a checkerboard. | |
− | + | Frequently used for transparancy effects in systems that cannot properly do them. [[Sega Saturn]] for one. The Saturn port of Castlevania: Symphony of the Night]] uses dithering for dialogue boxxes, whereas the original Playstation version has proper transparant boxes. | |

+ | The result is often lost in emulation due to PCs typically using VGA or HDMI cables. The dots or lines appear as they actually are with no blurring. Options: | ||
+ | *Remove the dithering entirely. Enabling 32bit colors in ps1 emulators achieves this | ||
+ | *Use a blurring or NTSC Composite shader which reproduces the same amount of blur as the original composite cables | ||
+ | *Use a dithering shader designed to just blend the dithering but does not blend the rest of the image. | ||
