SuperGrafx
The , also known as simply the SuperGrafx, is a fourth-generation home video game console manufactured by NEC Home Electronics and released in Japan in 1989. It is the successor system to the PC Engine, released two years prior. Originally known as the PC Engine 2 during production stages, it was purported as a true 16-bit home console, featuring improved graphics and audio capabilities over its predecessor. The console was rushed to market, released several months before its initial intended release date in 1990, only having modest updates to the hardware. With only six retail games released that took advantage of the console's hardware updates, the SuperGrafx was a commercial failure, selling only 75,000 units total. None of the hardware advancements it possessed were carried over to later PC Engine models, such as the Duo & the LD-ROM² PAC for the LaserActive. Hardware Compared to the PC Engine, the SuperGrafx has four times the amount of working RAM for the main CPU. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD-ROM²
The TurboGrafx-16, known in Japan as the , is a home video game console developed by Hudson Soft and manufactured by NEC. It was released in Japan in 1987 and in North America in 1989. The first console of the fourth generation, it launched in Japan to compete with Nintendo's Famicom, but its delayed U.S. debut placed it against the more advanced Sega Genesis and later the Super NES. The TurboGrafx-16 features an 8-bit CPU paired with dual 16-bit graphics processors, and supports up to 482 on-screen colors from a palette of 512. The "16" in the console’s North American branding was criticized as misleading. With dimensions of , the PC Engine remains the smallest major home console ever released. Games were initially released on HuCard cartridges, but the platform later supported additional formats requiring separate hardware: TurboGrafx-CD (''CD-ROM²'' in Japan) games on compact disc, SuperGrafx games on a new console variant, and LD-ROM² games on LaserDisc via the Las ...

Hudson Soft HuC6270
HuC6270 is a video display controller (VDC) developed by Hudson Soft and manufactured for Hudson Soft by Seiko Epson. This VDC was used in the PC Engine game console series produced by NEC Corporation, and the upgraded PC Engine SuperGrafx. Technical specification The HuC6270 generates a display signal composed a 9-bit stream pixel data with a color and palette indexes, and indication of whether the pixel corresponds to background (with x y scrolling) or sprites. This data can be used by a colour encoder to output graphics. It uses external VRAM via a 16-bit address bus. It can display up to 64 sprites on screen, with a maximum of 16 sprites per horizontal scan line. The minimum resolution is 256 × 224 pixels, with resolutions up to 512 × 240 being possible. Uses The HuC6270 was used in consoles of the PC Engine, SuperGrafx and TurboGrafx-16 ranges. Additionally, the VDC was used in arcade games: * '' Alien Crush'' * '' Blazing Lazers'' * '' Bloody Wolf'' * ''Fishin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Home Video Game Console
A home video game console is a video game console that is designed to be connected to a display device, such as a television, and an external power source as to play video games. While initial consoles were dedicated units with only a few games fixed into the electronic circuits of the system, most consoles since support the use of swappable game media, either through game cartridges, optical discs, or through digital distribution to internal storage. There have been numerous home video game consoles since the first commercial unit, the Magnavox Odyssey in 1972. Historically these consoles have been grouped into generations lasting each about six years based on common technical specifications. , there have been nine console generations, with the current leading manufacturers being Sony, Microsoft, and Nintendo, colloquially known as the "Big 3".

Fourth Generation Of Video Game Consoles
In the history of video games, the fourth generation of video game consoles, more commonly referred to as the 16-bit era, began on October 30, 1987, with the Japanese release of NEC Home Electronics' PC Engine (known as the TurboGrafx-16 in North America). Though NEC released the first console of this era, sales were mostly dominated by the rivalry between Sega and Nintendo across most markets: the Sega Genesis, Sega Mega Drive (known as the Sega Genesis in North America) and the Super Nintendo Entertainment System (known as the ''Super Famicom'' in Japan). Cartridge-based handheld game consoles became prominent during this time, such as the Game Boy, Nintendo Game Boy, Atari Lynx, Game Gear, Sega Game Gear and TurboExpress. Nintendo was able to capitalize on its success in the Third generation of video game consoles, third generation, and managed to win the largest worldwide market share in the fourth generation as well. However, particularly in the lucrative North American mark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HuCard
The (Known as the TurboChip in regions where the PC Engine was marketed as the TurboGrafx-16) is a ROM cartridge in the form of a card, designed by Hudson Soft for NEC's PC Engine and PC Engine SuperGrafx video game consoles, which were originally released in 1987 and 1989, respectively. Development The HuCard is an evolution from an earlier Hudson Soft technology, the Bee Card, which it developed in the early 1980s as a distribution medium for MSX software. The Bee Card is an EEPROM device that is slightly thinner than the HuCard. It has 32 connectors whereas the HuCard has 38. In July 1985, Hudson approached and pitched Nintendo a new add-on for the Famicom that played games using the patented Bee Cards. Nintendo liked this concept, as it had the ability to store full games and overwrite existing ones. However, as the technology for it was expensive, and that they would have to pay royalties for each card sold, Nintendo decided to pass on Hudson's proposal and woul ...

Hudson Soft HuC6280
The HuC6280 8-bit microprocessor is Japanese company Hudson Soft's improved version of the WDC 65C02 CPU, an upgraded CMOS version of the popular NMOS-based MOS Technology 6502 8-bit CPU, manufactured for Hudson by Seiko Epson and NEC. The most notable product using the HuC6280 is NEC's TurboGrafx-16 video game console. Description The HuC6280 contains a 65C02 core which has several additional instructions and a few internal peripheral functions such as an interrupt controller, a memory management unit, a timer, an 8-bit parallel I/O port, and a programmable sound generator (PSG). The processor operates at two speeds, 1.79 MHz and 7.16 MHz. A slightly revised HuC6280A was released and used in the PC Engine CoreGrafx and SuperGrafx. This revision reportedly fixed some minor audio issues in those systems.

Overscan
Overscan is a behaviour in certain television sets in which part of the input picture is cut off by the visible bounds of the screen. It exists because cathode-ray tube (CRT) television sets from the 1930s to the early 2000s were highly variable in how the video image was positioned within the borders of the screen. It then became common practice to have video signals with black edges around the picture, which the television was meant to discard in this way. Origins Early analog televisions varied in the displayed image because of manufacturing tolerance problems. There were also effects from the early design limitations of power supplies, whose DC voltage was not regulated as well as in later power supplies. This could cause the image size to change with normal variations in the AC line voltage, as well as a process called blooming, where the image size increased slightly when a brighter overall picture was displayed due to the increased electron beam current causing the CRT anod ...

Color Depth
Color depth, also known as bit depth, is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel. When referring to a pixel, the concept can be defined as bits per pixel (bpp). When referring to a color component, the concept can be defined as bits per component, bits per channel, bits per color (all three abbreviated bpc), and also bits per pixel component, bits per color channel or bits per sample. Modern standards tend to use bits per component, but historical lower-depth systems used bits per pixel more often. Color depth is only one aspect of color representation, expressing the precision with which the amount of each primary can be expressed; the other aspect is how broad a range of colors can be expressed (the gamut). The definition of both color precision and gamut is accomplished with a color encoding specification which assigns a digital code value to a location in a color space. The ...
