Agreed, love this kind of look. I emulated a curved screen, phosphor glow and scan lines somewhat in my Unreal Engine based Z80 emulators, although I think the look could still be improved further. This is fairly easy to do with UE4 shaders and geometry for the curved screen, a bit harder to do all from scratch though in a standalone program I would think.
