The version 1.70 update means that users can now download PlayStation format software that is compatible with the PS3. Downloaded games can be accessed via the XMB media bar home menu.

The same also goes for compatible games previously purchased for use on the PlayStation Portable, which are now compatible with the PS3.

PlayStation Portable games that have already been purchased can be downloaded to the PS3 without additional cost, although newly compatible PS1 titles are priced at $5.99.

Unfortunately the new update is not yet available to European PlayStation 3 owners.

The upgrade, available for download worldwide Thursday, will improve the visual quality of PlayStation 2 games, as well as original PlayStation games, although it won't be quite as dazzling as the quality of PS3 games, Sony Computer Entertainment Inc. officials said.

The software will also work to adjust the image quality of movies so they will look much better on the PS3, which is equipped to deliver higher image quality through next-generation Blu-ray disc technology.

Up to now, people could use the PlayStation Portable to watch content stored in their PS3 through a wireless local area network.
