The Sega Saturn (セガサターン), is a video game console manufactured by Sega and was the successor to the Sega Mega Drive/Genesis (as opposed to add-ons such as the Sega 32X and Mega-CD). Initially released in 1994, the Saturn was a 32-bit compact disc-based system, and was a key player in what is now widely known as the fifth generation of video game consoles. The Saturn was first released on November 22, 1994 in Japan, May 11, 1995 in North America, and July 8, 1995 in Europe.
Depending on where you live, the Saturn could be described as either Sega's most successful console of all time (Japan) or one of their biggest commercial failures (North America). Its complex hardware and inability to meet rapidly evolving consumer expectations and demands put it in a distant third place in the Western world, but a combination of above-average 2D rendering capabilities and a strong marketing campaign made the Saturn the most successful Sega console in Japan. Estimates for the total number of Saturns sold worldwide range from ten million to seventeen million.
The Saturn's main competitors were the Sony PlayStation released in 1995 and the Nintendo 64 released in 1996. Its arcade counterpart was the Sega Titan Video (ST-V). It was replaced by the Sega Dreamcast in late 1998.
The system uses CD-ROMs as its primary choice of media. Though it contains a cartridge slot, this is not used for games, but rather backup memory or RAM cartridges. The former was to extend the space for save games beyond that of the Saturn's internal memory, while the latter was used to augment the Saturn's limited memory and to avoid long CD load times.
The Saturn has two controller ports, and the standard Saturn controller builds on that seen in the six button Sega Mega Drive controller. It adds two shoulder buttons, first seen in the Super Nintendo, bringing the amount of buttons up to nine. The 3D Control Pad, released later with NiGHTS into Dreams, would supply the console with an analogue stick and analogue shoulder buttons, the latter later being used in the Sega Dreamcast before being adopted by Nintendo and Microsoft for their GameCube and Xbox consoles, respectively.
There are a variety of Sega Saturn models of different shapes and colours, as well as novelty units, such as the Game & Car Navi HiSaturn. Differences between systems are not as drastic as seen with the Sega Mega Drive - the same basic feature set and component designs were used throughout the console's lifespan in all regions.
First seen on launch day in Japan (1994-11-22), the HST-3200 (later revised and released as the HST-3210, although the differences aside from a BIOS update are not fully understood), commonly referred to as the "grey Saturn" (although during development it had a metallic finish), was the basis for all Sega Saturns released between the Japanese launch and early 1996. These Saturns use blue "oval" buttons, mounted to black plastic at the front of the unit, and have both "power" and "access" LEDs similar to the Sega Mega CD.
The Saturn saw variants produced by Hitachi and Victor as the HiSaturn and V-Saturn respectively, though aside from altered BIOSes and aesthetics (and bundles/pricing) these do not deviate much from the Sega designs. Novelty value sees these models worth slightly more in pre-owned markets - fewer were produced than the Sega models, but compatibility rates are much the same.
Overseas versions are physically identical (save for region encoding), but use black plastic throughout.
Released in March 1996, the HST-3220 stands as the only significant change to the Saturn's design, although functionality wise, the only feature omitted is the "access" LED seen in previous models. These "white" Saturns likely cost less to produce, but from a user perspective the change is largely negligible - the console is roughly the same size and has no problems running any Saturn software. White Saturns opt for grey "circle" power and reset buttons and a pink "open" button for lifting the lid.
It is rumoured, though not proven, that the HST-3220 has a faster disc reading time than its earlier counterparts, meaning quicker loading screens in games.
When brought overseas the console continued to be shipped only in black, although the North American and European models have different coloured buttons. In 1998 Sega started releasing these consoles with semi-transparent plastic under the "This is cool" brand - it is not known if these versions replaced the white models, or were sold alongside them. Again aside from aesthetic differences the consoles are interchangable.
Some of the Japanese colour designs were also brought to Brazil.

VDP1 transparency rendering quirk causes strips of pixels to be rewritten to framebuffer for 2-point (scaled) and 4-point (quadrangle) "sprites", applying the transparency effect multiple times. Rarely seen in commercial games (Robotica explosions), later titles implemented software transparency to correctly render polygons (Dural in Virtua Fighter Kids).
System RAM buses:
The Saturn supported the following resolutions: 
Japanese Saturn software usually came packaged in standard jewel cases, much like music CDs. They also came with spinecards - three-fold pieces of light cardboard that hug the spine of the jewel case. These are very valuable for collectors who wish to claim a game is "complete". The spinecard also indicates that the CD is for use with a Sega Saturn console - specifically Japanese NTSC systems. There were also jewel case quad CD cases, and a variant of the single case which was slightly thicker and VERY hard to replace.
Most of the time the spinecard will have a gold and black background with the Japanese Saturn logo and lettering printed vertically. Saturn collection games will have red and white spinecard with white lettering, the Saturn Collection logo under that, and the 2,800 yen price featured prominently. Manual is included with the cover seen through the front of the jewel case. The left side of the manual will usually have a bar similar in design to the spinecard. The Japanese SEGA rating, if there is one, will be included on the manual front (usually on one of the corners). There is also the insert on the back which may feature artwork or screenshots from the game. A black bar on the bottom of the insert contains information much like the spinecard, licensing information, et cetera.
The Japanese packaging was adopted in smaller Asian markets such as South Korea and China.
The US used much larger jewel cases identical to the US Sega Mega-CD jewel cases, since many of these were in fact leftover Sega CD jewel cases. The US case has a white spine containing a 30 degree stripe pattern in gray, with white outlined lettering displaying the words "Sega Saturn". Oddly some US packaging seems to have taken a step backwards in terms of aesthetics - with minimal front artwork almost akin to the Sega Master System.
There are many flaws with the US packaging:
European cases come in two variants, both designed and engineered by Sega. One has a strong plastic design similar to the cases used with the Mega Drive and Master System (but taller, thinner and slightly more secure). The other feels far cheaper, being literally two pieces of plastic held together by a cardboard cover. Though the former was more preferred by the consumer, the latter was more common as it was cheaper to produce.
Both European cases has a solid black spine, with white lettering displaying the words "Sega Saturn". The manual slides in the case just like a normal jewel case and there is a back insert with information about the game. Like the American cases they are still too big and can lead to discs moving about and becoming scratched, though this may be to compensate for large multi-language manuals.
Some European boxes were wrapped in a transparent plastic shell after manufacture for extra security.
Brazilian games were packaged in cardboard boxes, with a CD sleeve inside to keep the disc secure.
The Saturn is notoriously hard to emulate due to its complex architecture (dual processors, etc.), but three notable emulators do exist:
Software that plays files in the Saturn Sound Format, which stores audio ripped from games, does so through emulation of the audio-related code only.
