 NES. However, the NES would continue to dominate the gaming market for several years before Sega's system finally became successful. Nintendo executives were initially reluctant to design a new system, but they reconsidered when the NES hardware began to show its age. Seeing its dominance in the market slipping, Nintendo was compelled to create a new console to compete with its 16-bit rivals.

Console wars

The rivalry between Nintendo and Sega resulted in one of the fiercest console wars in video game history, in which Sega positioned the Genesis as the "cool" console, with more mature titles aimed at older gamers, and edgy advertisements that occasionally attacked the competition. Nintendo however, scored an early PR coup by securing the first console conversion of Capcom's arcade classic Street Fighter II

 for Super NES, which took over a year to make the transition to Genesis. Despite the Genesis' head start, much larger library of games, and lower price point, the Genesis only controlled an estimated 60% of the American 16-bit console market in April 1992, and neither console could maintain a definitive lead for several years. The Super NES would remain popular well into the 32-bit generation. According to Stephen Kent in 2001, the Super NES had eventually prevailed over the Sega Genesis in the American 16-bit console market. However, a 2004 study of NPD sales data presents new information that disputes this claim.

Changes in policy

During the NES era, Nintendo maintained exclusive control over titles released for the system—the company had to approve every game, each third-party developer could only release up to five games per year (but some third-parties got around this by using different names, for example Konami's "Ultra" brand), those games could not be released on another console within two years, and Nintendo was the exclusive manufacturer and supplier of NES cartridges. However, competition from Sega's console brought an end to this practice; in 1991, Acclaim

Nintendo of America also maintained a strict censorship policy that, among other things, limited the amount of violence in the games on its systems. One game, Mortal Kombat

In the last 45 days of 1994, the game sold 6.1 million units, making it the fastest-selling video game in history to that date. This game sent a message that early 32-bit systems had little to offer over the Super NES, and helped make way for the more advanced consoles on the horizon. The SNES continued to sell steadily throughout the 32-bit era.

In October 1997, Nintendo released a redesigned model of the SNES (the SNS-101 model) in North America for US$99, which included the pack-in game Super Mario World 2: Yoshi's Island

Emulation

Like the NES before it, the SNES has retained interest among its fans even following its decline in the marketplace. It has continued to thrive on the second-hand market and through console emulation. The SNES has taken much the same revival path as the NES (see History of the Nintendo Entertainment System).

Emulation projects began with the initial release of VSMC in 1994, and Super Pasofami became the first working SNES emulator in 1996. During that time, two competing emulation projects—Snes96 and Snes97—merged to form a new initiative entitled Snes9x

, while 448 and 478 resolutions are interlaced. Colors are chosen from the 15-bit RGB color space, for a total of 32,768 possible colors. Graphics consist of up to 128 sprites and up to 4 background layers, all made up of combinations of 8×8 pixel tiles. Most graphics use palettes stored in CGRAM, with color 0 of any palette representing transparency.

Sprites can be 8 × 8, 16 × 16, 32 × 32, or 64 × 64 pixels, each using one of eight 16-color palettes and tiles from one of two blocks of 256 in VRAM. Sprites may be flipped horizontally and vertically as a whole. Up to 32 sprites and 34 8 × 8 sprite tiles may appear on any one line; exceeding these limits causes excess sprites or tiles to be dropped. Each sprite lies on one of 4 planes, however a lower-numbered sprite will always cover a higher-numbered sprite even if the latter is on a higher priority plane. This quirk is often used for complex clipping effects.

Background layers in most modes range from 32 × 32 to 128 × 128 tiles, with each tile on one of two planes ("foreground" and "background") and using one of 8 palettes. Tiles are taken from a per-layer set of up to 1024 (as VRAM permits) and can be flipped horizontally and vertically. Each layer may be scrolled both horizontally and vertically. The number of background layers and the size of the palettes depends on the mode:
  • Mode 0: 4 layers, all using 4-color palettes. Each BG uses its own section of the SNES palette.
  • Mode 1: 3 layers, two using 16-color palettes and one using 4-color palettes.
  • Mode 2: 2 layers, both using 16-color palettes. Each tile can be individually scrolled.
  • Mode 3: 2 layers, one using the full 256-color palette and one using 16-color palettes. The 256-color layer can also directly specify colors from an 11-bit (RGB443) colorspace.
  • Mode 4: 2 layers, one using the full 256-color palette and one using 4-color palettes. The 256-color layer can directly specify colors, and each tile can be individually scrolled.
  • Mode 5: 2 layers, one using 16-color palettes and one using 4-color palettes. Tile decoding is altered to facilitate use of the 512-width and interlaced resolutions.
  • Mode 6: 1 layer, using 16-color palettes. Tile decoding is as in Mode 5, and each tile can be individually scrolled.

  • Mode 7

The PPU may be instructed to latch the current pixel position at any time during image output, both by game software and by the device attached to controller port 2. The game software may then read back this latched position. The PPU may also be used for fast 16-bit by 8-bit signed multiplication.

 of the console.

Internally, a regional lockout chip (CIC) within the console and in each cartridge prevents PAL region games from being played on Japanese or North American consoles and vice versa. The Japanese and North American machines have the same region chip. The console CIC releases the reset signal to the rest of the system only after completing a handshake with the chip in the cartridge. This can be overcome through the use of adapters, typically by inserting the imported cartridge in one slot and a cartridge with the correct region chip in a second slot. Alternatively, disconnecting one pin of the console's lockout chip will prevent it from locking the console; hardware in later games can detect this situation, so it later became common to install a switch to reconnect the lockout chip as needed.

PAL consoles face another incompatibility when playing out-of-region cartridges: the NTSC video standard

ing of the output image. Some commercial PAL region releases exhibit this same problem and therefore can be played in NTSC systems without issue, while others will face a 20% speedup if played in an NTSC console. To mostly correct this issue, a switch can be added to place the SNES PPU into a 60 Hz mode supported by most newer PAL televisions. Later games will detect this setting and refuse to run, requiring the switch to be thrown only after the check completes.

Enhancement chips

As part of the overall plan for the SNES, rather than include an expensive CPU that would still become obsolete in a few years, the hardware designers made it easy to interface special coprocessor chips to the console. This is most often characterized by 16 additional pins on the cartridge card edge.

Many cartridges contain other enhancement chips, most of which were created for use by a single company in a few titles; the only limitations are the speed of the Super NES itself to transfer data from the chip and the current

The SNES has often been considered among the best video game consoles ever. In 2007, GameTrailers named the Super NES as the second-best console of all time in their list of top ten consoles that "left their mark on the history of gaming", citing its graphic, sound, and library of top-quality games. Technology columnist Don Reisinger proclaimed "The SNES is the greatest console of all time" in January 2008, citing the quality of the games and the console's drastic improvement over its predecessor; fellow technology columnist Will Greenwald replied with a more nuanced view, giving the SNES top marks with his heart, the NES with his head, and the PlayStation (for its controller) with his hands. GamingExcellence also gave the SNES first place in 2008, declaring it "simply the most timeless system ever created" with many games that stand the test of time and citing its innovation in controller design, graphics capabilities, and game storytelling. At the same time, GameDaily rated it fifth of ten for its graphics, audio, controllers, and games. In 2009, IGN
