This is a simple tool to create a scanline effect for PSP games and homebrew.
I'd recommend trying this on an 'actual' PSP first instead of a Vita eCFW since it's in beta stages but It's been tested on PSTV and seems to work fine on that platform as well.
I completed this simple POC in under 2 hours with some modifications after googling for information since I had free time before bed. It has a 'shaky' effect from the scan-lines being drawn too (not really intended, but oh well).
Tested on 6.60 PRO-C (PSPGo).
Disclaimer:
Be warned that I'm not a graphics person and I did the best I could and it definitely needs improvement. Chances are that some games might run really slow. Or the scan-lines may/may not be produced in certain situations (I haven't tested it that much).
