Why you give a link to a forum that requires registration? It is not possible to organize a direct link?

It doesn't really look like a TV though. It's way too jaggy, and I can't see any colour bleeding or other analog artifacts on that screenshot. Blargg has a good filter that simulates an NTSC TV signal http://www.fly.net/~ant/libs/ntsc.html. I don't know if anything similar exists for PAL though.

This is just a develop edition.Later,I will port more filters in it.

You need to implement an color carrier frequency artefact (Blaargg call it "pixel artefact"). It is look's like net of dots (for NES and other) or vertical bars (for MD). This happens becouse used different methods for color carrier frequency syncronization to video signal. PlayStation has independ external (for video chip) PAL/NTSC coder, so it produce dot nets artefacts too, but that dots is always moving to left or right, becouse has no syncronization with video signal.

I think that thing looks ridiculous. Blargg's filter is just about dead on, but even it's not quite as noisy as I think is accurate for Never The Same Color

emulation. Everyone seems to think that dark scanlines = TV look.

I've always wanted to do a kpi plug based on the xscreensaver apple2 code.

It simulates bloom, ghosting and if I recall correctly some scanline shift.

By the way, no slam on you Dark--but definitely needs more work visually and maybe cut the darkness of the scanlines a bit
