Attribute Clash
Attribute clash (also known as colour clash or bleeding) is a display Visual artifact, artifact caused by limits in the graphics circuitry of some colour 8-bit home computers, most notably the ZX Spectrum, where it meant that only two colours could be used in any 8×8 tile of pixels. The effect was also noticeable on MSX software and in some Commodore 64 titles. Workarounds to prevent this limit from becoming apparent have since been considered an element of Spectrum programmer culture. This problem also happens with the "semigraphic modes" (text modes with graphics features) of the TRS-80 Color Computer, Color Computer and Dragon 32/64, Dragon, but those computers also have non-attributed graphics and with better resolution. Several video game consoles of the era had such video modes that caused such limitations, but usually allowed more than two colours per tile: the NES (Famicom) had only one mode, which was also "semigraphic", and allowed four colours per 16×16 "block" (gr ...

MSX Computer Color Limit
MSX is a standardized home computer architecture, announced by ASCII Corporation on June 16, 1983. It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, the director at ASCII Corporation. Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines. The first MSX computer sold to the public was a Mitsubishi ML-8000, released on October 21, 1983, thus marking its official release date. MSX systems were popular in Japan and several other countries. There are differing accounts of MSX sales. One source claims 9 million MSX units were sold worldwide, including in Japan alone, whereas ASCII Corporation founder Kazuhiko Nishi claims that 3 million were sold in Japan, and 1 million overseas. Despite Microsoft's involvement, few MSX-based machines were released in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Double Dragon (arcade Game)
is a 1987 beat 'em up video game developed by Technōs Japan and published by Taito for arcades. It is the first title in the ''Double Dragon'' franchise. The game's development was led by Yoshihisa Kishimoto, and it is a spiritual and technological successor to Technos' earlier beat 'em up, ''Nekketsu Kōha Kunio-kun'' (1986), released outside of Japan by Taito as ''Renegade''; Kishimoto originally envisioned it as a direct sequel and part of the '' Kunio-kun'' series, before making it a new game with a different cast and setting. ''Double Dragon'' introduced several additions to the ''Kunio-kun'' belt scroll beat 'em up formula, such as a continuous side-scrolling world adding a sense of progression, two-player cooperative gameplay, the ability to arm oneself with an enemy's weapon after disarming them, and the use of cut scenes to give it a cinematic look and feel. The game's title is a reference to the two-player gameplay and Bruce Lee's martial arts film ''Enter the Drag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knight Lore
''Knight Lore'' is a 1984 action-adventure game developed and published by Ultimate Play the Game, and written by company founders Chris and Tim Stamper. The game is known for its use of isometric graphics, which it further popularized in video games. In ''Knight Lore'', the player character Sabreman has forty days to collect objects throughout a castle and brew a cure to his werewolf curse. Each castle room is depicted in monochrome on its own screen and consists of blocks to climb, obstacles to avoid, and puzzles to solve. Ultimate released ''Knight Lore'' third in the Sabreman series but later claimed to have completed it first and withheld its release for a year to position the company advantageously in anticipation of the game's effect on the market. ''Knight Lore'' novel image masking technique, Filmation, let images appear to pass atop and behind each other without their contents colliding. This created the illusion of depth priority, which the computer did not na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three Weeks In Paradise
''Three Weeks in Paradise'' is a video game released in 1986 by Mikro-Gen for the ZX Spectrum and Amstrad CPC platforms. It is the last action-adventure platform in the Wally Week series. Gameplay The Week family are lost on a tropical island inhabited by a hostile local tribe - the " Can Nibbles". Herbert and Wilma (Wally's son and wife) have been captured and Wally must rescue them and build a raft to escape. The player controls Wally and must solve puzzles and avoid obstacles such as animals and natives - especially the tribal chief, who is patrolling the area. Each puzzle solved builds a piece of escape raft. As with previous Wally games humour plays an important part in both the gameplay and puzzle solving. The graphics were detailed and the Spectrum version had an option to switch off Wally's natural colour, which would remove the colour clash. The ZX Spectrum +128 version included enhanced sound and additional underwater screens with objects to use, but the rest of ...

Demoscene
The demoscene () is an international computer art subculture focused on producing demos: self-contained, sometimes extremely small, computer programs that produce audiovisual presentations. The purpose of a demo is to show off computer programming, programming, visual art, and musical skills. Demos and other demoscene productions (graphics, music, videos, games) are shared, voted on and released online at festivals known as Demoscene#Parties, demoparties. The scene started with the home computer revolution of the early 1980s, and the subsequent advent of software cracking. Crackers altered the code of computer games to remove copy protection, claiming credit by adding introduction screens of their own ("crack intro, cracktros"). They soon started competing for the best visual presentation of these additions. Through the making of intros and stand-alone demos, a new community eventually evolved, independent of the gaming and Warez scene, software sharing scenes. Demos are informa ...

Monochrome
A monochrome or monochromatic image, object or palette is composed of one color (or values of one color). Images using only shades of grey are called grayscale (typically digital) or black-and-white (typically analog). In physics, monochromatic light refers to electromagnetic radiation that contains a narrow band of wavelengths, which is a distinct concept. Application Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-red. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype ("blueprint") images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image. In computing, monochrome has two meanings: * it may mean having only one color which is either on or off (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Game
A video game or computer game is an electronic game that involves interaction with a user interface or input device (such as a joystick, game controller, controller, computer keyboard, keyboard, or motion sensing device) to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with Sound, audio complement delivered through loudspeaker, speakers or headphones, and sometimes also with other types of sensory feedback (e.g., haptic technology that provides Touch, tactile sensations). Some video games also allow microphone and webcam inputs for voice chat in online gaming, in-game chatting and video game livestreaming, livestreaming. Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and PC game, comp ...

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), ...
