BC games can't possibly be turned into "native" 1080p. They very will could be upscaled to 1080p though.

However, it is smart of Sony to copy the VC idea and put out its rich PS legacy as well.

In fact they can be rendered in 1080p.
To simplify, upscaling is about rendering at a given resolution which give you a picture, say a 320x200 for PS1, then make every pixel bigger to fit an higher resolution. A simple upscaler just make pixel bigger. A good upscaling will not just make pixel bigger, but filter pixels to render sub pixel in a less visible way. It will produce a very mixed result.

An other way through emulation is to render directly the 3D at the target result. To say it very simply, if you have a line going from A to B, instead of making rendering it in a 320x200 matrix, you render in a 1080p matrix. You can add filter for textures to improve the rendering, and even tweaks some know effects. For example most of the game will render a semi transparent window using the same primitives, so you can render it with a beautifull modern gpu accelerated transparency. There is about no limit on how you could enhance the graphics, like replacing 8 bits low res textures with high res procedural textures, adding shaders depending of the game type.

So, that's really a native 1080p. The only problem is that the game is not made for that, so you can have a lot of code that produce glitches, etc., you have lot of game to test and simply can't achieve a 100% compatibilty.

Anyway, here are the pics from epsxe, the ps1/2 PC emulator that render this way. You can see the limitations, the background is a picture in 2d so you can't do better rendering, just add a blurry upscale.

You can watch shaders experimentation on youtube (switch to 720p or 1080p) : http://www.youtube.com/watch?v=2CWmrMyOl9o

This is exactly what I was thinking the game is cleaner but the textures are still blurry and polygons are more pronounced and blocky. I was always of the view that native 1080p meant cleaner textures (or more detailed textures if you like).
