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] |
Scan Line
A scan line (also scanline) is one line, or row, in a raster scanning pattern, such as a line of video on a cathode-ray tube (CRT) display of a television set or computer monitor. On CRT screens the horizontal scan lines are visually discernible, even when viewed from a distance, as alternating colored lines and black lines, especially when a progressive scan signal with below maximum vertical resolution is displayed. This is sometimes used today as a visual effect in computer graphics. The term is used, by analogy, for a single row of pixels in a raster graphics image. Scan lines are important in representations of image data, because many image file formats have special rules for data at the end of a scan line. For example, there may be a rule that each scan line starts on a particular boundary (such as a byte or word; see for example BMP file format). This means that even otherwise compatible raster data may need to be analyzed at the level of scan lines in order to conver ...

Pac-Land
is a 1984 platform video game developed and published by Namco for arcades. It was distributed in North America by Bally Midway, and in Europe by Atari Games. Controlling Pac-Man, the player must make it to the end of each stage to return a lost fairy back to its home in Fairyland. Pac-Man will need to avoid obstacles, such as falling logs and water-spewing fire hydrants, alongside his enemies, the Ghost Gang. Eating large flashing Power Pellets will cause the ghosts to turn blue, allowing Pac-Man to eat them for points. ''Pac-Land'' was created by Namco Research and Development 1 programmer Yoshihiro Kishimoto, who was tasked with creating an arcade game based on the American ''Pac-Man'' cartoon television series by Hanna-Barbera. The backgrounds were made to be vibrant and colorful, and the characters to be detailed and move smoothly to match the show's animation style. The control scheme was inspired by Konami's ''Track & Field'' (1983), using buttons instead of a tradit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blazing Lazers
known as in North America, is a vertically scrolling shooter game by Hudson Soft and Compile (company), Compile, based on the Japanese film ''Gunhed (film), Gunhed''. The title was released in 1989, for the PC Engine in Japan and re-skinned for the TurboGrafx-16 in North America, with ''Gunhed'' unofficially imported for the PC Engine in Europe. In the game, a fictional galaxy is under attack by an enemy space armada called the Dark Squadron, and this galaxy's only chance for survival is the Gunhed Advanced Star Fighter, who must destroy the Dark Squadron and its Super Weapons. The gameplay features fast vertical scrolling and a wide array of weapons for the player to use. ''Blazing Lazers'' was produced by the same personnel who developed other video game series such as ''Puyo Puyo'' and ''Super Bomberman'' as well as other games such as ''Zanac'', ''The Guardian Legend'', and ''DoReMi Fantasy: Milon's DokiDoki Adventure''. It was one of the first games released for the TurboGr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alien Crush
''Alien Crush'' is a pinball video game developed by Compile for the PC Engine/TurboGrafx-16. It was released in 1988. The game is the first installment in the '' Crush Pinball'' series. It was followed by three sequels, '' Devil's Crush'', '' Jaki Crush'', and ''Alien Crush Returns''. ''Alien Crush'' was later re-released via emulation on the Virtual Console for Wii, 3DS, and Wii U, and for PlayStation 3 through PlayStation Network. ''Alien Crush'' garnered generally favorable reception from critics, some of which reviewed it as an import title; praise was given to the unusual and original graphical design reminiscent of the '' Alien'' films, realistic physics, accessibility towards less experienced players and playability but some felt divided regarding its audio, while the transition between the two screens and lack of variety in gameplay aside from the bonus rounds were seen as negative points. Retrospective commentary has been mostly positive. Gameplay ''Alien Crush'' fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TurboGrafx-16
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 of video game consoles, fourth generation, it launched in Japan to compete with Nintendo's Family Computer, Famicom, but its delayed U.S. debut placed it against the more advanced Sega Genesis and later the Super Nintendo Entertainment System, Super NES. The TurboGrafx-16 features an 8-bit computing, 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.

Video Random-access Memory
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. It often uses a different technology than other computer memory, in order to be read quickly for display on a screen. Relation to GPUs Many modern GPUs rely on VRAM. In contrast, a GPU that does ''not'' use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory. System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs, and to achieve lower latency, since VRAM is physically closer to the GPU die. Modern VRAM is typically found in a Ball grid array, BGA package soldered onto a graphics card. The VRAM is cooled along with the GPU by the GPU heatsink. Technologies * Dual-ported video RAM, used in the 1990s and at the time often called "VRAM" * SGRAM * GDDR SDRAM * High Bandwidth Memory (HBM) See also * Graphics processing unit * ...

Video Display Controller
A video display controller (VDC), also called a display engine or display interface, is an integrated circuit which is the main component in a video-signal generator, a device responsible for the production of a TV video signal in a computing or game system. Some VDCs also generate an audio signal, but that is not their main function. VDCs were used in the home computers of the 1980s and also in some early video picture systems. The VDC is the main component of the video signal generator logic, responsible for generating the timing of video signals such as the horizontal and vertical synchronization signals and the blanking interval signal. Sometimes other supporting chips were necessary to build a complete system, such as RAM to hold pixel data, ROM to hold character fonts, or some discrete logic such as shift registers. Most often the VDC chip is completely integrated in the logic of the main computer system, (its video RAM appears in the memory map of the main CPU), ...

Sprite (computer Graphics)
In computer graphics, a sprite is a Plane (mathematics), two-dimensional bitmap that is integrated into a larger scene, most often in a 2D video game. Originally, the term ''sprite'' referred to fixed-sized objects composited together, by hardware, with a background. Use of the term has since become more general. Systems with hardware sprites include arcade video games of the 1970s and 1980s; game consoles including as the Atari VCS (1977), ColecoVision (1982), Nintendo Entertainment System, Famicom (1983), Sega Genesis, Genesis/Mega Drive (1988); and home computers such as the TI-99/4 (1979), Atari 8-bit computers (1979), Commodore 64 (1982), MSX (1983), Amiga (1985), and X68000 (1987). Hardware varies in the number of sprites supported, the size and colors of each sprite, and special effects such as scaling or reporting pixel-precise overlap. Hardware composition of sprites occurs as each scan line is prepared for the video output device, such as a cathode-ray tube, without i ...

Scrolling
In computer displays, filmmaking, television production, video games and other kinetic displays, scrolling is sliding text, images or video across a monitor or display, vertically or horizontally. "Scrolling," as such, does not change the layout of the text or pictures but moves ( pans or tilts) the user's view across what is apparently a larger image that is not wholly seen. A common television and movie special effect is to scroll credits, while leaving the background stationary. Scrolling may take place completely without user intervention (as in film credits) or, on an interactive device, be triggered by touchscreen or a keypress and continue without further intervention until a further user action, or be entirely controlled by input devices. Scrolling may take place in discrete increments (perhaps one or a few lines of text at a time), or continuously (smooth scrolling). Frame rate is the speed at which an entire image is redisplayed. It is related to scrolling in that chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
