Is there EASY test for BAD GTIA in late model XE (China)

[Rybags]

There was one mod around (Polish?) that buffered the AN0-AN2 signals that go from Antic to GTIA. Not sure to what extent it fixed the problem though.

Thanks! Right after I posted, I found your reply on this thread: http://atariage.com/forums/topic/233858-testing-gtia/. I meant to come back here and say as much, but I forgot. So is there a common video mod that would help?

Yes - search for UAV (from member Bryan). It completely eliminates this issue, as well as giving the best video quality via luma/chroma that can be had. only way for better video is one of the RGB solutions (sopiha or VBXE2).
