History

There were a few problems around the launch of the system. Only a few million users had obtained consoles by the end of 2000 due to hardware shortages. Developers also complained about the system being difficult to develop for, with little in the way of reference material from Sony for its exotic architecture. Although the PS2 launch seemed unimpressive and gaffe-prone, compared to well-planned launch of the Sega Dreamcast which was making a genuine attempt to woo developers and which had better launch titles, the PS2 initially sold well solely on the basis of the strength of the PlayStation brand and its backwards compatibility, allowing the PS2 to tap the large installed base established by the PlayStation. Another major selling point over the Dreamcast was the PlayStation 2's ability to play DVDs and this gained the PS2 a presence in electronics stores that formerly didn't sell video game consoles. Later Sony gained steam with new development kits for game developers and more PlayStations for consumers.

Many experts predicted a close 3-way matchup between the PS2 and its soon-to-be-released competitors Microsoft Xbox and Nintendo GameCube, noting that the PS2's graphics were inferior but it had the advantage of a head start (Xbox's strength was in its hardware, GameCube was the cheapest of the 3 consoles). However, the release of several blockbuster games during the 2001 holiday season pushed the PS2 far in front even as the Xbox and GameCube made their impressive debuts. Not since the days of the NES has a console dominated the market to the extent that PS2 has.

Despite the PS2's dominance, the advent of the Xbox and GameCube has hurt Sony's profits due to all 3 rivals lowering their console prices (already below break-even point) in a price war, and because Sony Computer Entertainment is the subsidiary that accounts for over half of Sony's profits.

Hardware sales remained strong until 2004 saw the console apparently approaching saturation point. In September of that year, in time for the launch of Grand Theft Auto: San Andreas (the highest selling game during the 2004 Holiday season), Sony revealed a new, smaller PS2 (see Hardware revisions).

Sony had stopped making the older PS2 model (SCPH-5000x) sometime during the summer of 2004 to let the distribution channel empty out stock of the units. After an apparent manufacturing issue caused some initial slowdown in producing the new unit, Sony reportedly underestimated demand, caused in part by shortages between the time the old units were cleared out and the new units were ready. This led to further shortages, and the issue was compounded in Britain when a Russian oil tanker became stuck in the Suez Canal, blocking a ship from China carrying PS2s bound for the UK. During one week in November, sales in the entire country of Britain totalled 6,000 units - compared to 70,000 a few weeks prior. [1] Shortages in the US were also extremely severe; one retail chain in the U.S., GameStop, had just 186 PS2 and Xbox units on hand across more than 1700 stores on the day before Christmas. [2]

Games

The PlayStation brand's strength has lead to strong third-party support for the system. Although the launch titles for the PS2 were unimpressive in 2000, the holiday season of 2001 saw the release of several best-selling and critically acclaimed games. Those PS2 titles helped the PS2 maintain and extend its lead in the video game console market, despite increased competition from the successful launches of the Microsoft Xbox and Nintendo GameCube. Critically acclaimed games on the machine are the Grand Theft Auto and Final Fantasy series, the latest two Metal Gear Solid titles, all three Devil May Cry titles, latest three Ace Combat titles, the Square Enix/Disney collaboration Kingdom Hearts and its upcoming sequel Kingdom Hearts II, and first-party Sony Computer Entertainment brands such as the Gran Turismo, SOCOM, Ratchet & Clank and Jak and Daxter series, ICO, God of War and the Everquest spin-offs Champions of Norrath and Champions: Return to Arms.

Hardware compatibility

The PS2 can read and play both compact discs and DVDs, it is backwards compatible with older PlayStation (PS1) games and allowing for playback of DVD Video and the more technically advanced PS2 games on either cheaper, smaller CD-ROM format or the larger, more expensive DVD-ROM format. The ability to play DVD movies allowed consumers to more easily justify the PS2's relatively high price tag (in October 2000, the MSRP was $300) as it removed the need to buy an external DVD player (indeed, it could be said that the success of the DVD format was partly down to the PS2's ability to play DVDs, as the format seemed to appeal more to consumers after the console's launch). The PS2 also supports PS1 memory cards (for PS1 game saves only) and controllers (the PS2's Dual Shock 2 controller is essentially a slightly upgraded PS1 Dual Shock).

When it was released, the PS2 had many advanced features that were not present in other contemporary video game consoles, including its DVD capabilities and USB and IEEE 1394 expansion ports. It was not until late 2001 that the Microsoft Xbox became the second console with (non-standard) USB and DVD support (this is assuming the Nuon, an advanced DVD player graphics coprocessor, is not considered a console).

[edit]

Software compatibility

Support for original PlayStation games was also an important selling point for the PS2, letting owners of an older system upgrade to the PlayStation 2 and keep their old software, and giving new users access to older games until a larger library was developed for the new system. As an added bonus, the PS2 had the ability to enhance PlayStation games by speeding up disc read time and/or adding texture smoothing to improve graphics. While the texture smoothing was universally effective (albeit with odd effects where transparent textures are used), faster disk reading could cause some games to fail to load or play correctly.

A handful of PlayStation titles (notably Metal Gear Solid: Special Missions) fail to run on the PS2 at all (Special Missions fails to recognise Metal Gear Solid at the disk swap screen, for example). It is a common misconception that disk swapping in a game (for example, for multi-disk games or expansion packs) is not possible on the PS2. The anomalous failure of the above title at its disk swap screen may have given birth to this rumor. Software for all PlayStation consoles contains one of three region codes: for Japan and Asia: NTSC/J, North America: NTSC-U/C and Europe and Oceania: PAL.

Home development

The PlayStation 2 has undergone many revisions, some only of internal construction and others with substantial external changes. These are colloquially known amongst PlayStation 2 hardware hackers as V0, V1, V2, etc., up to V12 (as of November 25, 2004).

V0 was a Japanese model and was never sold in Europe or the US. These included a PCMCIA slot instead of the Expansion Bay (DEV9) port of newer models. V0 did not have a built-in DVD player and instead relied on an encrypted player that was copied to a memory card from an included CD-ROM (normally, the PS2 will only execute encrypted software from its memory card, but see PS2 Independence Exploit). V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards. As of V4 everything was unified into one board, except the power supply. V5 introduces minor internal changes and the only difference between V6 (sometimes called V5.1) and V5 is the orientation of the Power/Reset switch board connector, which was reversed to prevent the use of no-solder modchips. V7 and V8 are also similar, and V9 (model number SCPH-50000/SCPH-50001) added the Infrared port for the optional DVD Remote Control, removed the widely unused FireWire port, added the capability to read DVD-RW discs, and a quieter fan. V10 and V11 have minor changes.

In September 2004 Sony unveiled the third major hardware revision (V12, model number SCPH-70000). Available in November 2004, it is smaller and thinner than the old version and includes a built-in Ethernet port. In some markets it also integrates a modem. Due to its thinner profile, it does not contain the 3.5" expansion bay, and therefore does not support the internal hard disk drive. This poses a problem for games such as Final Fantasy XI, which requires the use of this peripheral, and prevents the use of the official PS2 Linux kit, although a workaround may be possible. It is widely believed that Sony has abandoned support for the hard drive. There are also some disputes on the numbering for this PS2 version, since there are actually two sub-versions of the SCPH-70000. One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical. Since the V12 version had already been established for this model, there were some disputes regarding these sub-versions. Two propositions were to name the old model (EE and GS, separate chips) V11.5 and the newer model V12, and to name the old model V12 and the newer model V13. Currently, most people just use V12 for both models, or V12 for the old model and V13 for the newer one. The new V12 model was first released in black. A silver edition is available in the United Kingdom exclusively. It is unknown whether or not this will follow the color schemes of the older model.

Sony has also made a PVR/DVD burning consumer device that plays PlayStation 2 games called the PSX. The device was poorly received, with some major features absent from the first revisions of the hardware, and has thus far experienced very poor sales in Japan, in spite of major price drops [3]. The machine's future continues to be uncertain, with North American and European launches considered to be distant if at all.
