Y'know, i've heard PS2 was pain to work with, and i can tell by PCSX2 that, indeed, emulation still isn't all that great, and, is missing some effects like fog, light rays, and motion blur, which were popular around this time. (and are in L'sV on real hardware), and doesn't run very well, i wonder, does that have something to do with that? Like, it's all reverse engineered and figured out, but not fully known...?

I'd like to know.
