PS1 catalogue on PS3 not yet playable

Speaking with 1UP, Sony's Phil Harrison detailed plans to make most of the PlayStation (PS1) catalogue available for download on PlayStation 3 -- in addition to PSP. Harrison confirmed that a few titles will be available at launch, including Twisted Metal and Syphon Filter. The catch is you'll have to play them on your PSP, since PS3 currently lacks PS1 emulation software.

Once the patch is distributed though -- Harrison hopes by year's end -- each PS1 download will be playable on both PS3 and PSP, allowing us to enjoy treasured classics and rarities on-the-go and on the big screen. Just be warned, PS1 games will not be enhanced for your 1080p display.

Note: Actual PS1 discs will be playable at launch.
