You know - PS1 games have a resolution of 320x240 pixels. Using "normal" mode in the PSP's (perfect) Playstation-emulator this 240 lines height get scaled up to the PSP's 272 pixels height (while keeping the 4:3 aspect ratio). It looks great - it doesn't look as if some lines were doubled and some not - that's because of interpolation.
It's a bit blurry - but that's not a problem for me.
So you can also scale 256 lines up to 480 by interpolation without doubling them.
