Producing Artifacting Colors On Gp2x With Tv-out (for Atari 800, Trs-8

[slaanesh]

Is it possible to produce artifacting colors on GP2X with TV-out? (for Atari 800, TRS-80, etc)

I know that the Atari 800 emulator does this already natively, but what I want to know is can you re-produce it in the same way that it used to happen on old TV sets? Or does this specifically require a TV set with RF to reproduce?

I know it's not possible to produce on a PAL TV.

EDIT:
For those who don't know what artifacting is, it's a color effect created by changing neighbouring pixels from on to off (or vice versa) to create other colors. Often used in Atari 800s and TRS-80 computers.
Common artifacting colors are blue and reddy/brown. Without artifacting colors will just be white/black.

ie. TRS-80 artifact colors
Atari 8-bit artifact colors

no clue, but maybe it could work to put a cap on the chroma signal of the s-video cable?

possibly with an S-Video to RCA converter like I use it would be possible, but I'm no programmer!
