Difficult current question: why does the Atari 2600's display change colours as the display tries to achieve horizontal lock? Phase should be unchanged. Ergo something is amiss.

Not that they're drawn from correctly yet. I might first take a run at a new quick-path output route for emulated RGB displays, that just seeks to use the scans directly. No intermediate buffers. Besides probably being a good feature, it'll be a good way to ramp further up with Metal.
