The NGP will also be able to upscale and adapt older PlayStation Portable titles, as well. The only one we saw in action was the third-person Resistance: Retribution, which you were able to control with both of the NGP's analog sticks. Visually, the game looked great, bumped up to a higher resolution that gave it a clear edge over playing it on a PSP.
The game's developer, Sony Bend, says it didn't have to do anything to make this happen; the NGP does all of the heavy lifting, adapting titles for the platform itself. How this works and how many games will support this functionality is a mystery, as Sony was being tight-lipped on specifics. Still, the idea of being able to play older PSP titles on your new consoles with dual analog controls and at a higher resolution is certainly attractive.
