Potrait Mode of Playing Games - WITH EASE-CLARITY

[LunaMoo]

Dunno what you want as an additional features, because Display Layout Editor can be used to move display around easily and edit touch control layout can do same about controls. The only thing you can't do is to change the aspect ratio, PSP games are widescreen not some square weirdness from NES, most you could do is to zoom into it enough to hide left and right parts of the screen.
