Removable test or visual artifact?

When I load up a ROM in Exodus, there's a strip of colors on the bottom left of the that look like 11 shaking pebbles of the rainbow. They appear outside of the actual gameplay itself but it's very distracting. How can I stop these from appearing?

Huh... very interesting. Thank you, Stef, I never noticed that sitting far away with a bubble glassed television set. Appreciate you taking the time to tell me.

Those are bus conflicts resulting from writing to CRAM midframe. They're unavoidable on hardware, and also why commercial games generally wait until VInt to write to CRAM (or if they do write to CRAM mid-frame, they either limit the amount of data they write, or attempt to make the shitpixels less noticable by putting sprites on the same scanlines like the Sonic games do on the water surface).
