Several consoles such as the Master System and the TurboGrafx-16 have used different types of smart cards as an external medium. These cards function similar to simple cartridges. Information is stored on a chip that is housed in plastic. Cards are more compact and simpler than cartridges, though. This makes them cheaper to produce and smaller, but limits what can be done with them. Cards cannot hold extra components, and common cartridge techniques like bank switching (a technique used to create very large games) were impossible to miniaturize into a card in the late 1980s. Compact Discs reduced much of the need for cards. Optical Discs can hold more information than cards, and are cheaper to produce. The Nintendo GameCube and the PlayStation 2 use memory cards for storage, but the PlayStation Vita, Nintendo 3DS, and Nintendo Switch are currently the only modern systems to use cards for game distribution. Nintendo has long used cartridges with their Game Boy line of hand held consoles because of their durability, small size, stability (not shaking and vibrating the handheld when it is in use), and low battery consumption. Nintendo switched to cards starting with the DS, because advances in memory technology made putting extra memory on the cartridge unnecessary. The PlayStation Vita uses Sony's own proprietary flash-memory Vita cards as one method of game distribution.
You don’t have to buy the current machines if all you fancy is a few hours of nostalgic button bashing. Nintendo has released two retro machines, The Mini NES (£50) and Mini SNES (£70), which both provide more than 20 built-in games, while Sony’s PlayStation Classic (£90) comes crammed with favourites from the original PlayStation. Nothing brings a family together at Christmas like Double Dragon II: The Revenge.
Sega released the Mega Drive in Japan on October 29, 1988, though the launch was overshadowed by Nintendo's release of Super Mario Bros. 3 a week earlier. Positive coverage from magazines Famitsu and Beep! helped to establish a following, but Sega only managed to ship 400,000 units in the first year. In order to increase sales, Sega released various peripherals and games, including an online banking system and answering machine called the Sega Mega Anser. Nevertheless, the Mega Drive was unable to overtake the venerable Famicom and remained a distant third in Japan behind Nintendo's Super Famicom and NEC's PC Engine throughout the 16-bit era.
The term "video game console" is primarily used to distinguish a console machine primarily designed for consumers to use for playing video games, in contrast to arcade machines or home computers. An arcade machine consists of a video game computer, display, game controller (joystick, buttons, etc.) and speakers housed in large chassis. A home computer is a personal computer designed for home use for a variety of purposes, such as bookkeeping, accessing the Internet and playing video games. While arcades and computers are generally expensive or highly “technical” devices, video game consoles were designed with affordability and accessibility to the general public in mind.
