Speed Demos Archive
Speed Demos Archive (commonly known as simply SDA) is a website dedicated to video game speedruns. SDA's primary focus is hosting downloadable, high-quality speedrun videos, and currently has runs of over eleven hundred games, with more being added on a regular basis. SDA additionally used to host two annual speedrunning charity marathons, Awesome Games Done Quick (AGDQ) and Summer Games Done Quick (SGDQ), before Games Done Quick LLC started holding the event independently in 2015. It hosted nine marathons in total, and raised over $2.7 million for various charities, with the most successful one being AGDQ 2014 which raised just over $1 million for the Prevent Cancer Foundation. History SDA originally began as a demo archive of '' Quake'' playthroughs. SDA was formed initially by Nolan "Radix" Pflug of Pittsburgh, Pennsylvania by merging with a site created by Gunnar and Jesse in April 1998. In 2004, after the success of his own 100% ''Metroid Prime'' run, Radix expanded ...

Video Game
Video games, also known as computer games, are electronic games that involves interaction with a user interface or input device such as a joystick, controller, keyboard, or motion sensing device to generate visual feedback. This feedback mostly commonly is shown on a video display device, such as a TV set, monitor, touchscreen, or virtual reality headset. Some computer games do not always depend on a graphics display, for example text adventure games and computer chess can be played through teletype printers. Video games are often augmented with audio feedback delivered through speakers or headphones, and sometimes with other types of feedback, including haptic technology. Video games are defined based on their platform, which include arcade video games, console games, and personal computer (PC) games. More recently, the industry has expanded onto mobile gaming through smartphones and tablet computers, virtual and augmented reality systems, and remote c ...

TheSpeedGamers
TheSpeedGamers (also abbreviated as TSG or TSG.TV) is a group of video gamers based out of Arlington, Texas, who raise money for various charities. They accomplish this by streaming live marathons of video games on Twitch (formerly Justin.tv). The group was founded by Britt LaRiviere in early 2008 and still hosts marathons regularly through the year. Viewers can interact with the commentators and other viewers via chat on Twitch. The group has raised over $845,000.00 for more than 20 different charities. History Britt LaRiviere founded the group in March 2008. LaRiviere originally imagined the site as a source for gaming reviews, but over time, the idea evolved into forming a marathon group. Finally, they decided that if they ran marathons, then they should do it for a worthy cause. They adopted a Speedrun mentality and ran their first marathon, with a Zelda theme.''McGee, Maxwell'High Scores for Hope2009-2-24. Retrieved on 2010-1-28 Since then, the group has continued on ...

Game Balance
Game balance is a branch of game design that is described as a mathematical-algorithmic model of a game’s numbers, game mechanics, and relations between the two. Game balance consists of adjusting values to create a certain user experience. Players’ perception and experience are the objectives of game balancing. Overview and development Similar to game design, the definition of game balance is different between various game designers and developers. Game balance is present in every type of game in some form, so there are no existing comparable interpretations of the concept. Even so, game balance is generally understood as introducing a level of fairness for the players. This includes adjusting difficulty, win-loss conditions, game states, economy balancing, and so on to work in tandem with each other. The concept of game balance depends entirely on the type of game being discussed. Most game designers agree that game balancing serves towards providing an engaging player exp ...

Time Attack
Time attack is a type of motorsport in which the racers compete for the best lap time. Each vehicle is timed through numerous circuits of the track. The racers make a preliminary circuit, then run the timed laps, and then finish with a cool-down lap. Time attack and time trial events differ by competition format and rules. Time attack has a limited number of laps, time trial has open sessions. Unlike other timed motorsport disciplines such as sprinting and hillclimbing, the car is required to start off under full rolling start conditions following a warm up lap in which they will have to accelerate out as fast as possible to determine how fast they enter their timed lap.Time Attack FAQ's
Commonly, as the cars are modified road going cars, they are required to have tires authorized for road use. Time attack events began in Japan i ...

DVD Recorder
A DVD recorder is an optical disc recorder that uses optical disc recording technologies to digitally record analog or digital signals onto blank writable DVD media. Such devices are available as either installable drives for computers or as standalone components for use in television studios or home theater systems. As of March 1, 2007 all new tuner-equipped television devices manufactured or imported in the United States must include an ATSC tuner. The US Federal Communications Commission (FCC) has interpreted this rule broadly, including apparatus such as computers with TV tuner cards with video capture ability, videocassette recorders and standalone DVD recorders. NTSC DVD recorders are undergoing a transformation, either adding a digital ATSC tuner or removing over-the-air broadcast television tuner capability entirely. However, these DVD recorders can still record analog audio and analog video. Standalone DVD recorders, alongside Blu-ray recorders, have been ...

TV Tuner Card
A TV tuner card is a kind of television tuner that allows television signals to be received by a computer. Most TV tuners also function as video capture cards, allowing them to record television programs onto a hard disk much like the digital video recorder (DVR) does. The interfaces for TV tuner cards are most commonly either PCI bus expansion card or the newer PCI Express (PCIe) bus for many modern cards, but PCMCIA, ExpressCard, or USB devices also exist. In addition, some video cards double as TV tuners, notably the ATI All-In-Wonder series. The card contains a tuner and an analog-to-digital converter (collectively known as the analog front end) along with demodulation and interface logic. Some lower-end cards lack an onboard processor and, like a Winmodem, rely on the system's CPU for demodulation. Types There are many types of tuner cards. Analog tuners Analog television cards output a raw video stream, suitable for real-time viewing but ideally requiring some sort ...

Speedrun
Speedrunning is the act of playing a video game, or section of a video game, with the goal of completing it as fast as possible. Speedrunning often involves following planned routes, which may incorporate sequence breaking and can exploit glitches that allow sections to be skipped or completed more quickly than intended. Tool-assisted speedrunning is a sub-category of speedrunning that uses emulation software to slow the game down and create a precisely controlled sequence of inputs. Many online communities develop around speedrunning specific games; community leaderboard rankings for individual games form the primary competitive metric for speedrunning. Racing between two or more speedrunners is also a popular form of competition. Videos and livestreams of speedruns are shared via the internet on media sites such as YouTube and Twitch. Speedruns are sometimes showcased at marathon events, which are gaming conventions that feature multiple people performing speedruns in a ...

DOSBox
DOSBox is a free and open-source emulator which runs software for MS-DOS compatible disk operating systems—primarily video games. It was first released in 2002, when DOS technology was becoming obsolete. Its adoption for running DOS games is widespread, with it being used in commercial re-releases of those games as well. DOSBox can be downloaded and used from the video game console emulator front-end RetroArch. Development Before Windows XP, consumer-oriented versions of Windows were based on MS-DOS. Windows 3.0 and its updates were operating environments that ran on top of MS-DOS, and the Windows 9x series consisted of operating systems that were still based on MS-DOS. These versions of Windows could run DOS applications. Conversely, the Windows NT operating systems were not based on DOS. A member of the series is Windows XP, which debuted on October 25, 2001, to become the first consumer-oriented version of Windows to not use DOS. Although Windows XP could emulate DO ...

Virtual Machines
In computing, a virtual machine (VM) is the virtualization/ emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination. Virtual machines differ and are organized by their function, shown here: * '' System virtual machines'' (also termed full virtualization VMs) provide a substitute for a real machine. They provide functionality needed to execute entire operating systems. A hypervisor uses native execution to share and manage hardware, allowing for multiple environments which are isolated from one another, yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, virtualization-specific hardware, primarily from the host CPUs. * Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU and vid ...

Virtual Console
A virtual console (VC) – also known as a virtual terminal (VT) – is a conceptual combination of the keyboard and display for a computer user interface. It is a feature of some Unix-like operating systems such as Linux, BSD, illumos, UnixWare, and macOS in which the system console of the computer can be used to switch between multiple virtual consoles to access unrelated user interfaces. Virtual consoles date back at least to XenixUnited States Patent 4945468 lists Xenix as prior art in this area. and Concurrent CP/M in the 1980s. In the Linux console and other platforms, usually the first six virtual consoles provide a text terminal with a login prompt to a Unix shell. The graphical X Window System traditionally starts in the seventh virtual console (tty7), although this is configuration dependent. In Linux, the user switches between them by pressing the Alt key combined with a function key – for example + to access the virtual console number 1. + changes to the ...
