Microsoft Windows is a group of several graphical operating system families, all of which are developed and sold by Microsoft. Each family caters to a certain sector of the computing industry. Active Windows families include Windows Embedded. Defunct Windows families include Windows Mobile and Windows Phone. Microsoft introduced an operating environment named Windows on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces. Microsoft Windows came to dominate the world's personal computer market with over 90% market share, overtaking Mac OS, introduced in 1984. Apple came to see Windows as an unfair encroachment on their innovation in GUI development as implemented on products such as the Lisa and Macintosh. On PCs, Windows is still the most popular operating system. However, in 2014, Microsoft admitted losing the majority of the overall operating system market to Android, because of the massive growth in sales of Android smartphones.
In 2014, the number of Windows devices sold was less than 25 %. This comparison however may not be relevant, as the two operating systems traditionally target different platforms. Still, numbers for server use of Windows show one third market share, similar to that for end user use; as of October 2018, the most recent version of Windows for PCs, tablets and embedded devices is Windows 10. The most recent versions for server computers is Windows Server 2019. A specialized version of Windows runs on the Xbox One video game console. Microsoft, the developer of Windows, has registered several trademarks, each of which denote a family of Windows operating systems that target a specific sector of the computing industry; as of 2014, the following Windows families are being developed: Windows NT: Started as a family of operating systems with Windows NT 3.1, an operating system for server computers and workstations. It now consists of three operating system subfamilies that are released at the same time and share the same kernel: Windows: The operating system for mainstream personal computers and smartphones.
The latest version is Windows 10. The main competitor of this family is macOS by Apple for personal computers and Android for mobile devices. Windows Server: The operating system for server computers; the latest version is Windows Server 2019. Unlike its client sibling, it has adopted a strong naming scheme; the main competitor of this family is Linux. Windows PE: A lightweight version of its Windows sibling, meant to operate as a live operating system, used for installing Windows on bare-metal computers, recovery or troubleshooting purposes; the latest version is Windows PE 10. Windows IoT: Initially, Microsoft developed Windows CE as a general-purpose operating system for every device, too resource-limited to be called a full-fledged computer. However, Windows CE was renamed Windows Embedded Compact and was folded under Windows Compact trademark which consists of Windows Embedded Industry, Windows Embedded Professional, Windows Embedded Standard, Windows Embedded Handheld and Windows Embedded Automotive.
The following Windows families are no longer being developed: Windows 9x: An operating system that targeted consumers market. Discontinued because of suboptimal performance. Microsoft now caters to the consumer market with Windows NT. Windows Mobile: The predecessor to Windows Phone, it was a mobile phone operating system; the first version was called Pocket PC 2000. The last version is Windows Mobile 6.5. Windows Phone: An operating system sold only to manufacturers of smartphones; the first version was Windows Phone 7, followed by Windows Phone 8, the last version Windows Phone 8.1. It was succeeded by Windows 10 Mobile; the term Windows collectively describes any or all of several generations of Microsoft operating system products. These products are categorized as follows: The history of Windows dates back to 1981, when Microsoft started work on a program called "Interface Manager", it was announced in November 1983 under the name "Windows", but Windows 1.0 was not released until November 1985.
Windows 1.0 was to achieved little popularity. Windows 1.0 is not a complete operating system. The shell of Windows 1.0 is a program known as the MS-DOS Executive. Components included Calculator, Cardfile, Clipboard viewer, Control Panel, Paint, Reversi and Write. Windows 1.0 does not allow overlapping windows. Instead all windows are tiled. Only modal dialog boxes may appear over other windows. Microsoft sold as included Windows Development libraries with the C development environment, which included numerous windows samples. Windows 2.0 was released in December 1987, was more popular than its predecessor. It features several improvements to the user memory management. Windows 2.03 changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit against Microsoft alleging infringement on Apple's copyrights. Windows 2.0
The Dreamcast is a home video game console released by Sega on November 27, 1998 in Japan, September 9, 1999 in North America, October 14, 1999 in Europe. It was the first in the sixth generation of video game consoles, preceding Sony's PlayStation 2, Nintendo's GameCube and Microsoft's Xbox; the Dreamcast was Sega's final home console, marking the end of the company's 18 years in the console market. In contrast to the expensive hardware of the unsuccessful Sega Saturn, the Dreamcast was designed to reduce costs with "off-the-shelf" components, including a Hitachi SH-4 CPU and an NEC PowerVR2 GPU. Released in Japan to a subdued reception, the Dreamcast enjoyed a successful U. S. launch backed by a large marketing campaign, but interest in the system declined as Sony built hype for the upcoming PlayStation 2. Sales did not meet Sega's expectations despite several price cuts, the company continued to incur significant financial losses. After a change in leadership, Sega discontinued the Dreamcast on March 31, 2001, withdrawing from the console business and restructuring itself as a third-party publisher.
9.13 million Dreamcast units were sold worldwide. Although the Dreamcast had a short lifespan and limited third-party support, reviewers have considered the console ahead of its time, its library contains many games considered creative and innovative, including Crazy Taxi, Jet Set Radio and Shenmue, as well as high-quality ports from Sega's NAOMI arcade system board. The Dreamcast was the first console to include a built-in modem for Internet support and online play. Released in 1988, the Sega Genesis was Sega's entry into the fourth generation of video game consoles. Selling 30.75 million units worldwide, the Genesis was the most successful console Sega released. The successor to the Genesis, the Sega Saturn, was released in Japan in 1994; the Saturn was a CD-ROM-based console that displayed both 2D and 3D computer graphics, but its complex dual-CPU architecture made it more difficult to program for than its chief competitor, the Sony PlayStation. Although the Saturn debuted before the PlayStation in both Japan and the United States, its surprise U.
S. launch—which came four months earlier than scheduled—was marred by a lack of distribution, which remained a continuing problem for the system. Moreover, Sega's early release was undermined by Sony's simultaneous announcement that the PlayStation would retail for US$299—compared to the Saturn's initial price of $399. Nintendo's long delay in releasing a competing 3D console and the damage done to Sega's reputation by poorly supported add-ons for the Genesis allowed Sony to establish a foothold in the market; the PlayStation was successful in the U. S. in part due to a massive advertising campaign and strong third-party support engendered by Sony's excellent development tools and liberal $10 licensing fee. Sony's success was further aided by a price war in which Sega lowered the price of the Saturn from $399 to $299 and from $299 to $199 in order to match the price of the PlayStation–even though Saturn hardware was more expensive to manufacture and the PlayStation enjoyed a larger software library.
Losses on the Saturn hardware contributed to Sega's financial problems, which saw the company's revenue decline between 1992 and 1995 as part of an industry-wide slowdown. Furthermore, Sega's focus on the Saturn over the Genesis prevented it from capitalizing on the continued strength of the 16-bit market. Due to long-standing disagreements with Sega of Japan, Sega of America CEO Tom Kalinske became less interested in his position. On July 16, 1996, Sega announced that Shoichiro Irimajiri had been appointed chairman and CEO of Sega of America, while Kalinske would be leaving Sega after September 30 of that year. Sega announced that Sega Enterprises cofounder David Rosen and Sega of Japan CEO Hayao Nakayama had resigned from their positions as chairman and co-chairman of Sega of America, though both men remained with the company. Bernie Stolar, a former executive at Sony Computer Entertainment of America, was named Sega of America's executive vice president in charge of product development and third-party relations.
Stolar did not support the Saturn due to his belief that the hardware was poorly designed and publicly announced at E3 1997 that "The Saturn is not our future." After the launch of the Nintendo 64, sales of the Saturn and Sega's 32-bit software were reduced. As of August 1997, Sony controlled 47 percent of the console market, Nintendo controlled 40 percent, Sega controlled only 12 percent. Neither price cuts nor high-profile games were proving helpful to the Saturn's success. Due to the Saturn's poor performance in North America, Sega of America laid off 60 of its 200 employees in the fall of 1997; as a result of the company's deteriorating financial situation, Nakayama resigned as president of Sega in January 1998 in favor of Irimajiri. Stolar would subsequently accede to become president of Sega of America. Following five years of declining profits, in the fiscal year ending March 31, 1998, Sega suffered its first parent and consolidated financial losses since its 1988 listing on the Tokyo Stock Exchange.
Due to a 54.8% decline in consumer product sales, the company reported a consolidated net loss of ¥35.6 billion. Shortly before announcing its financial losses, Sega revealed that it was discontinuing the Saturn in North America, with the goal of preparing for the launch of its successor; this decision left the Western market without Sega games for over one year. Rumors about the upcoming Dreamcast—spread by Sega itself—leaked to the public before the last Saturn games were release
Linux is a family of free and open-source software operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is packaged in a Linux distribution. Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian and Ubuntu. Commercial distributions include SUSE Linux Enterprise Server. Desktop Linux distributions include a windowing system such as X11 or Wayland, a desktop environment such as GNOME or KDE Plasma. Distributions intended for servers may omit graphics altogether, include a solution stack such as LAMP; because Linux is redistributable, anyone may create a distribution for any purpose. Linux was developed for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other operating system.
Linux is the leading operating system on servers and other big iron systems such as mainframe computers, the only OS used on TOP500 supercomputers. It is used by around 2.3 percent of desktop computers. The Chromebook, which runs the Linux kernel-based Chrome OS, dominates the US K–12 education market and represents nearly 20 percent of sub-$300 notebook sales in the US. Linux runs on embedded systems, i.e. devices whose operating system is built into the firmware and is tailored to the system. This includes routers, automation controls, digital video recorders, video game consoles, smartwatches. Many smartphones and tablet computers run other Linux derivatives; because of the dominance of Android on smartphones, Linux has the largest installed base of all general-purpose operating systems. Linux is one of the most prominent examples of open-source software collaboration; the source code may be used and distributed—commercially or non-commercially—by anyone under the terms of its respective licenses, such as the GNU General Public License.
The Unix operating system was conceived and implemented in 1969, at AT&T's Bell Laboratories in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, Joe Ossanna. First released in 1971, Unix was written in assembly language, as was common practice at the time. In a key pioneering approach in 1973, it was rewritten in the C programming language by Dennis Ritchie; the availability of a high-level language implementation of Unix made its porting to different computer platforms easier. Due to an earlier antitrust case forbidding it from entering the computer business, AT&T was required to license the operating system's source code to anyone who asked; as a result, Unix grew and became adopted by academic institutions and businesses. In 1984, AT&T divested itself of Bell Labs; the GNU Project, started in 1983 by Richard Stallman, had the goal of creating a "complete Unix-compatible software system" composed of free software. Work began in 1984. In 1985, Stallman started the Free Software Foundation and wrote the GNU General Public License in 1989.
By the early 1990s, many of the programs required in an operating system were completed, although low-level elements such as device drivers and the kernel, called GNU/Hurd, were stalled and incomplete. Linus Torvalds has stated that if the GNU kernel had been available at the time, he would not have decided to write his own. Although not released until 1992, due to legal complications, development of 386BSD, from which NetBSD, OpenBSD and FreeBSD descended, predated that of Linux. Torvalds has stated that if 386BSD had been available at the time, he would not have created Linux. MINIX was created by Andrew S. Tanenbaum, a computer science professor, released in 1987 as a minimal Unix-like operating system targeted at students and others who wanted to learn the operating system principles. Although the complete source code of MINIX was available, the licensing terms prevented it from being free software until the licensing changed in April 2000. In 1991, while attending the University of Helsinki, Torvalds became curious about operating systems.
Frustrated by the licensing of MINIX, which at the time limited it to educational use only, he began to work on his own operating system kernel, which became the Linux kernel. Torvalds began the development of the Linux kernel on MINIX and applications written for MINIX were used on Linux. Linux matured and further Linux kernel development took place on Linux systems. GNU applications replaced all MINIX components, because it was advantageous to use the available code from the GNU Project with the fledgling operating system. Torvalds initiated a switch from his original license, which prohibited commercial redistribution, to the GNU GPL. Developers worked to integrate GNU components with the Linux kernel, making a functional and free operating system. Linus Torvalds had wanted to call his invention "Freax", a portmant
The PlayStation 2 is a home video game console, developed by Sony Computer Entertainment. It is the successor to the original PlayStation console and is the second iteration in the PlayStation lineup of consoles, it was released in 2000 and competed with Sega's Dreamcast, Nintendo's GameCube and Microsoft's Xbox in the sixth generation of video game consoles. Announced in 1999, the PlayStation 2 offered backwards compatibility for its predecessor's DualShock controller, as well as for its games; the PlayStation 2 is the best-selling video game console of all time, selling over 155 million units, with 150 million confirmed by Sony in 2011. More than 3,874 game titles have been released for the PS2 since launch, more than 1.5 billion copies have been sold. Sony manufactured several smaller, lighter revisions of the console known as Slimline models in 2004. In 2006, Sony announced and launched its successor, the PlayStation 3. With the release of its successor, the PlayStation 2 remained popular well into the seventh generation and continued to be produced until January 4, 2013, when Sony announced that the PlayStation 2 had been discontinued after 12 years of production – one of the longest runs for a video game console.
Despite the announcement, new games for the console continued to be produced until the end of 2013, including Final Fantasy XI: Seekers of Adoulin for Japan, FIFA 13 for North America, Pro Evolution Soccer 2014 for Europe. Repair services for the system in Japan ended on September 7, 2018. Though Sony has kept details of the PlayStation 2's development secret, work on the console began around the time that the original PlayStation was released. Insiders stated that it was developed in the U. S. West Coast by former members of Argonaut Software. By 1997 word had leaked to the press that the console would have backwards compatibility with the original PlayStation, a built-in DVD player, Internet connectivity. Sony announced the PlayStation 2 on March 1, 1999; the video game console was positioned as a competitor to Sega's Dreamcast, the first sixth-generation console to be released, although the main rivals of the PS2 were Nintendo's GameCube and Microsoft's Xbox. The Dreamcast itself launched successfully in North America that year, selling over 500,000 units within two weeks.
Soon after the Dreamcast's North American launch, Sony unveiled the PlayStation 2 at the Tokyo Game Show on September 20, 1999. Sony showed playable demos of upcoming PlayStation 2 games including Gran Turismo 2000 and Tekken Tag Tournament – which showed the console's graphic abilities and power; the PS2 was launched in March 2000 in Japan, October in North America, November in Europe. Sales of the console and accessories pulled in $250 million on the first day, beating the $97 million made on the first day of the Dreamcast. Directly after its release, it was difficult to find PS2 units on retailer shelves due to manufacturing delays. Another option was purchasing the console online through auction websites such as eBay, where people paid over a thousand dollars for the console; the PS2 sold well on the basis of the strength of the PlayStation brand and the console's backward compatibility, selling over 980,000 units in Japan by March 5, 2000, one day after launch. This allowed the PS2 to tap the large install base established by the PlayStation – another major selling point over the competition.
Sony added new development kits for game developers and more PS2 units for consumers. The PS2's built-in functionality expanded its audience beyond the gamer, as its debut pricing was the same or less than a standalone DVD player; this made the console a low cost entry into the home theater market. The success of the PS2 at the end of 2000 caused Sega problems both financially and competitively, Sega announced the discontinuation of the Dreamcast in March 2001, just 18 months after its successful launch; the PS2 remained as the only active sixth generation console for over 6 months, before it would face competition from newer rivals. Many analysts predicted a close three-way matchup among the three consoles. While the PlayStation 2 theoretically had the weakest specification of the three, it had a head start due to its installed base plus strong developer commitment, as well as a built-in DVD player. While the PlayStation 2's initial games lineup was considered mediocre, this changed during the 2001 holiday season with the release of several blockbuster games that maintained the PS2's sales momentum and held off its newer rivals.
Sony countered the Xbox by temporarily securing PlayStation 2 exclusives for anticipated games such as the Grand Theft Auto series and Metal Gear Solid 2: Sons of Liberty. Sony cut the price of the console in May 2002 from US$299 to $199 in North America, making it the same price as the GameCube and $100 less than the Xbox, it planned to cut the price in Japan around that time. It cut the price twice in Japan in 2003. In 2006, Sony cut the cost of the console in anticipation of the release of the PlayStation 3. Sony, unlike Sega with its Dreamcast placed little emphasis on online gaming during its first few years, although that changed upon the launch of the online-capable Xbox. Coinciding with the release of Xbox Live, Sony released the PlayStation Network Adapter in late 2002, with several online first–party titles released alongside it, such as SOCOM: U. S. Navy SEALs to demon
A video game is an electronic game that involves interaction with a user interface to generate visual feedback on a two- or three-dimensional video display device such as a TV screen, virtual reality headset or computer monitor. Since the 1980s, video games have become an important part of the entertainment industry, whether they are a form of art is a matter of dispute; the electronic systems used to play video games are called platforms. Video games are developed and released for one or several platforms and may not be available on others. Specialized platforms such as arcade games, which present the game in a large coin-operated chassis, were common in the 1980s in video arcades, but declined in popularity as other, more affordable platforms became available; these include dedicated devices such as video game consoles, as well as general-purpose computers like a laptop, desktop or handheld computing devices. The input device used for games, the game controller, varies across platforms. Common controllers include gamepads, mouse devices, the touchscreens of mobile devices, or a person's body, using a Kinect sensor.
Players view the game on a display device such as a television or computer monitor or sometimes on virtual reality head-mounted display goggles. There are game sound effects and voice actor lines which come from loudspeakers or headphones; some games in the 2000s include haptic, vibration-creating effects, force feedback peripherals and virtual reality headsets. In the 2010s, the commercial importance of the video game industry is increasing; the emerging Asian markets and mobile games on smartphones in particular are driving the growth of the industry. As of 2015, video games generated sales of US$74 billion annually worldwide, were the third-largest segment in the U. S. entertainment market, behind broadcast and cable TV. Early games used interactive electronic devices with various display formats; the earliest example is from 1947—a "Cathode ray tube Amusement Device" was filed for a patent on 25 January 1947, by Thomas T. Goldsmith Jr. and Estle Ray Mann, issued on 14 December 1948, as U. S.
Patent 2455992. Inspired by radar display technology, it consisted of an analog device that allowed a user to control a vector-drawn dot on the screen to simulate a missile being fired at targets, which were drawings fixed to the screen. Other early examples include: The Nimrod computer at the 1951 Festival of Britain; each game used different means of display: NIMROD used a panel of lights to play the game of Nim, OXO used a graphical display to play tic-tac-toe Tennis for Two used an oscilloscope to display a side view of a tennis court, Spacewar! used the DEC PDP-1's vector display to have two spaceships battle each other. In 1971, Computer Space, created by Nolan Bushnell and Ted Dabney, was the first commercially sold, coin-operated video game, it used a black-and-white television for its display, the computer system was made of 74 series TTL chips. The game was featured in the 1973 science fiction film Soylent Green. Computer Space was followed in 1972 by the first home console. Modeled after a late 1960s prototype console developed by Ralph H. Baer called the "Brown Box", it used a standard television.
These were followed by two versions of Atari's Pong. The commercial success of Pong led numerous other companies to develop Pong clones and their own systems, spawning the video game industry. A flood of Pong clones led to the video game crash of 1977, which came to an end with the mainstream success of Taito's 1978 shooter game Space Invaders, marking the beginning of the golden age of arcade video games and inspiring dozens of manufacturers to enter the market; the game inspired arcade machines to become prevalent in mainstream locations such as shopping malls, traditional storefronts and convenience stores. The game became the subject of numerous articles and stories on television and in newspapers and magazines, establishing video gaming as a growing mainstream hobby. Space Invaders was soon licensed for the Atari VCS, becoming the first "killer app" and quadrupling the console's sales; this helped Atari recover from their earlier losses, in turn the Atari VCS revived the home video game market during the second generation of consoles, up until the North American video game crash of 1983.
The home video game industry was revitalized shortly afterwards by the widespread success of the Nintendo Entertainment System, which marked a shift in the dominance of the video game industry from the United States to Japan during the third generation of consoles. A number of video game developers emerged in Britain in the early 1980s; the term "platform" refers to the specific combination of electronic components or computer hardware which, in conjunction with software, allows a video game to operate. The term "system" is commonly used; the distinctions below are not always clear and there may be games that bridge one or more platforms. In addition to laptop/desktop computers and mobile devices, there are other devices which have the ability to play games but are not video game machines, such as PDAs and graphing calculators. In common use a "PC game" refers to a form of media that involves a player interacting with a personal computer conne
Neo Geo CD
Neo Geo CD is the second home video game console of SNK Corporation's Neo Geo family, released in September 9, 1994, four years after its cartridge-based equivalent. This is the same platform, converted to the cheaper CD format retailing at $49 to $79 per title, compared to the $300 cartridges; the system was priced at US$399, or £399 in the UK. The unit's 1X CD-ROM drive is slow, with long loading times of up to 56 Mbit of data per load; the system can play Audio CDs. All three versions of the system have no region-lock; the Neo Geo CD was launched bundled with a control pad instead of a joystick like the AES version. However, the original AES joystick can be used with all three Neo Geo CD models; as of March 1997, there had been 570,000 Neo Geo CD units sold worldwide. The Neo Geo CD was first unveiled at the 1994 Tokyo Toy Show; the console uses the same CPU set-up as the arcade and cartridge-based Neo Geo systems, facilitating conversions. SNK planned to release Neo Geo CD versions of every Neo Geo game still in the arcades.
Three versions of the Neo Geo CD were released: A front-loading version, only distributed in Japan, with 25,000 total units built. A top-loading version, marketed worldwide, as the most common model; the Neo Geo CDZ, an upgraded, faster-loading version, released in Japan only. The front-loading version is the original console design, with the top-loading version having been developed shortly before the Neo Geo CD launch as a scaled-down, cheaper alternative model; the CDZ was released on December 29, 1995 as the Japanese market replacement for SNK's previous efforts. The Neo Geo CD had met with limited success due to it being plagued with slow loading times that could vary from 30 to 60 seconds between loads, depending on the game. In response to criticism of the Neo Geo CD's long load times, SNK planned to produce a model with a double speed CD-ROM drive for North America, compared to the single speed drive of the Japanese and European models. However, the system missed its planned North American launch date of October 1995, while SNK declined to give a specific reason for the delay, in their announcement of the new January 1996 launch date they stated that they had decided against using a double speed drive.
Their Japanese division had produced an excess number of single speed units and found that modifying these units to double speed was more expensive than they had thought, so SNK opted to sell them as they were, postponing production of a double speed model until they had sold off the stock of single speed units. The CDZ was only sold in Japan during its production. However, its faster loading times, lack of a "region lock", the fact that it could play older CD software, made it a popular import item for enthusiasts in both Europe and North America; the system's technical specs are identical to the previous models except that it includes a double-speed CD-ROM drive. In response to reader inquiries about Neo Geo CD software, GamePro reported in an issue cover dated May 1997 that SNK had discontinued the console by this time. Criticism of the system's long loading times began before launch; the prototype of the machine that they showed was single speed, the load time was 14-28 seconds between rounds.
You can see that the screen on the right is a load screen."Approximately one month after launch, SNK reported that they had sold the Neo Geo CD's entire initial shipment of 50,000 units. Reviewing the Neo Geo CD in late 1995, Next Generation noted SNK's reputation for fun games but argued that their failure to upgrade the Neo Geo system with 3D capabilities would keep them from producing any "cutting edge" games, limit the console to the same small cult following as the Neo Geo AES system although with less expensive games, they gave it 1 1/2 out of 5 stars. Main Processor: Motorola 68000 running at 12 MHz Although the original 68000 CPU was designed by Motorola, there are many clones of this CPU found in the Neo Geo hardware; the most common CPU is the TMP68HC000 manufactured by Toshiba. Coprocessor: Zilog Z80 running at 4 MHz Colors On Screen: 4,096 Colors Available: 65,536 Resolution: 304 x 224 Max Sprites: 384 Max Sprite Size: 16 x 512 Number of Planes: 3 The system is capable of reading Redbook standard compact disc audio.
In addition to the multi-AV port, all Neo Geo CD models had composite RCA A/V and S-Video out jacks on the rear of the console. The CD system's 56 Mbit / 7 MB of RAM was split accordingly: 68000 Program Memory: 2 MB Fix Layer Memory: 128 KB Graphics Memory: 4 MB Sound Sample Memory: 1 MB Z80 Program Memory: 64 kB VRAM: 512Kb SRAM: 2 KB While the Neo Geo CD library consists of ports of MVS and AES titles, there are a few MVS arcade games which were not released for the Neo Geo AES and ported instead to the Neo Geo CD; these include Puzzle Bobble, Janshin Densetsu: Quest of Jongmaster, Power Spikes II, Neo Drift Out: New Technology, Pleasure Goal: 5-on-5 Mini Soccer. A few games which were unreleased in MVS and AES formats were released for the Neo Geo CD; these include Ironclad: Tesshō Rusha, Crossed Swords II, ZinTrick, ADK World, Neo Geo CD Special, The King of Fighters'96 Neo Collec
