The original PlayStation sometimes garnered the abbreviation “PSX,” however Sony actually released a variant of the PlayStation 2 of the same moniker.

Only released in Japan, the system was mainly marketed as a digital video recorder, touting PS2 hardware and a few other notable features such as PSP linking and video/audio editing.

The device is a fully functional digital video recorder with an included Infrared remote control and S-Video, composite video, and RFinputs. It is able to tune analog VHF and CATV. It can also be linked with a PlayStation Portable to transfer videos and music via USBports,^[3] and features software for non-linear video editing, image editing and audio editing.^[4] DVD+R support was to be introduced in a future update.^{[needs update]}

It was the first device to use Sony’s XrossMediaBar (XMB) graphical user interface, which was later used on the PlayStation Portable,PlayStation 3, and 2008-era BRAVIA TVs.

The PSX fully supports both PlayStation and PlayStation 2 software by its slot-loading DVD drive, as the onboard EE+GS chip is a unification of the PS2’s Emotion Engine and Graphics Synthesizer chips. Online game compatibility is available using the broadband connection; Games that use the PS2 HDD (such as Final Fantasy XI) are supported as well.^[5]

While the PSX is not supplied with any game controllers, there are two controller ports on the back of the device. Black or Ceramic WhiteDualShock 2‘s with 4-meter long cables were sold separately,^[6] and standard DualShock and DualShock 2 controllers were also compatible. Two PlayStation memory card ports were on the front of the PSX, behind a panel cover.^[7]

Like the “regular” PlayStation 2 models, the PSX can be laid horizontally or stood vertically.
