When the PlayStation 2 computer entertainment system was announced, the DualShock 2 Analog Controller (SCPH-10010) included with it was almost exactly the same externally as the previous DualShock analog controller, except that it was black (colors came later), had different screw positioning (one fewer), and the DualShock 2 logo was added. Another way to tell the DualShock and the DualShock 2 controllers apart is that the connector that plugs into the console matches that console’s memory card shape; the DualShock’s connector has rounded shoulders and DualShock 2’s is squared off. The analogue sticks were also noticeably stiffer for more accurate movements. Internally, the DualShock 2 was lighter and all of the buttons (except for the Analog mode, L3 and R3 buttons) were readable as analog values (pressure sensitive). The official DUALSHOCK2 analog controller delivers pressure sensitivity on every action button and the enhanced mobility of the analog thumbsticks.

EyeToy USB Camera

The EyeToy USB camera translates for EyeToy compatible games your body movements into the controller input, to map your face onto in-game characters and more! The EyeToy USB camera also has a built-in microphone to record short video messages right onto your Memory Card (8MB) for PlayStation 2.

Memory Cards (8MB) for PlayStation 2

For game saves and other essential information, you’ll need a Memory card for the PlayStation2. Save game progress, hidden characters, high scores, special weapons, hard levels, and custom controller settings. The official Memory Card for the PlayStation 2 system stores up to 8MB of data and features MagicGate encryption. The PlayStation 2 delivers more data-intensive games, so this extra capacity is invaluable.

DVD Remote Control

Play your favorite movies without any wires. The DVD remote has all the features of a standard controller with added enhanced DVD capabilities, plus standard game control functionality. A 8MB Memory Card 8MB is required for use with model numbers SCPH-300001 and SCPH-300001GT.

AV Connection Cable

This AV Connection Cable allows you to hook up a camcorder or other video equipment to your PSone console and LCD Screen so you can watch home movies and other videos while you travel! The AV Connection Cable can be used to connect the LCD screen to most Sony camcorders and other video equipment that has an AV output mini-jack. (Check to make sure your camcorder or video source has one of these before purchasing. The AV connection cable is not compatible with all products that have an AV output mini-jack. Compatibility depends on the AV signal layout of the mini-jack and not all AV equipment uses the same AV signal layout as the cable.)

Compatibility – Hardware and Software

In addition to PS2 software, the PS2 can read both CDs and DVDs and is backward compatible with PlayStation games. The PS2 also supports PlayStation memory cards (for PlayStation game saves only) and controllers, although the memory cards only work with PS1 games and the controllers may not support all functions (such as analog buttons) for PS2 games.

The PS2′s DualShock 2 controller is essentially an upgraded PlayStation DualShock; analog face, shoulder and D-pad buttons replaced the digital buttons of the original. Like its predecessor, the DualShock 2 controller has force feedback, which is commonly called the “vibration” function. The standard PlayStation 2 memory card has an 8MB capacity and uses Sony’s MagicGate encryption. This requirement prevented the production of memory cards by third parties who did not purchase a license for the MagicGate encryption. Memory cards without encryption can be used to store PlayStation game saves, but PlayStation games would be unable to read from or write to the card – such a card could only be used as a backup.

The console also features USB and IEEE 1394 expansion ports. Compatibility with USB and IEEE 1394 devices is dependent on the software supporting the device. For example, the PS2 BIOS will not boot an ISO image from a USB flash drive or operate a USB printer, as the machine’s operating system does not include this functionality. By contrast, Gran Turismo 4 is programmed to save screenshots to a USB mass storage device and print images on certain USB printers. A PlayStation 2 HDD can be installed in an expansion bay on the back of the console, with some exceptions.
