Currently, most people just use V12 for both models, or V12 for the old model and V13 for the newer one.
The PlayStation 2 holds the record of fastest selling video game console ever, 100 million PlayStation 2 units were shipped in only five years and nine months, shattering the previous record of nine years and six months by the PlayStation.
V0 was a Japanese model and was never sold in Europe or the US.
Sony has also made a PVR/DVD burning consumer device that plays PlayStation 2 games called the PSX.
For some consumers this is in fact a limitation, especially for the fans of titles such as Final Fantasy XI, which requires the use of this peripheral, and prevents the use of the official PS2 Linux kit.
In some markets it also integrates a modem.
Although Sony placed little emphasis on online gaming during its first year, all that changed because of the launch of the online-capable Xbox.
Available in November 2004, it is smaller and thinner than the old version and includes a built-in Ethernet port.
Many analysts 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 that it had the advantage of a head start, and had a wide assortment of games of every genre (Xbox's strength was in its hardware; GameCube was the cheapest of the 3 consoles).
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
The PS2 launch seemed unimpressive and gaffe-prone, compared to the well-planned launch of the Sega Dreamcast, which was making a genuine attempt to woo developers and which had better launch titles.
These included a PCMCIA slot instead of the Expansion Bay (DEV9) port of newer models.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
With a price of $299.99 per console, Sony made gross sales of roughly $153,000,000.
